Dub Name Change/Japanese to English

A

 * Akumajou Dracula to Castlevania
 * The Belmondo clan to the Belmont clan
 * Ralph C. Belmondo to Trevor Belmont
 * Johnny Morris to John Morris
 * Soma Kurusu to Soma Cruz

B

 * Beyblade
 * Takao Kinomiya to Tyson Granger
 * Max Mizuhara to Max Tate
 * Hiromi to Hilary
 * The first Breath of Fire had the names of a great deal of the characters (as well as spells, towns, enemies, items...everything) changed due to both name length issues in Super NES games and Square producing the North American localisation.
 * Gilliam to Bo
 * Danc to Karn
 * Builder to Ox
 * Manillo to Gobi
 * Deis to Bleu (This has caused some minor continuity issues with later games)
 * Zorgon to Zog
 * Judas to Jade
 * Kyura to Cort
 * Sigmund to Mote
 * Carla to Cerl
 * Breath of Fire II also had a number of name changes, largely to preserve puns and due to technical issues with the name length again.
 * Bosch (Boche in the credits) to Bow.
 * Rinpoo to Katt
 * Tapeta to Jean
 * Aspara to Spar
 * Deis to Bleu
 * Argus to Augus
 * Nimpho to Nimufu
 * Barbaroi to Barubary
 * Habalq to Habaruku (Babaruku in his boss fight)
 * Alzheimer to Aruhamel Aruhameru in his boss fight)
 * Breath of Fire III has a few, mostly to preserve puns or due to space issues, yet again:
 * Pecoros to Peco
 * Garland to Garr
 * Babaderu to Bunyan (setting up for a Mythology Gag in IV; the original Japanese name in III is itself a Mythology Gag in reference to a Mini Boss in II)
 * Zurusuru to Loki
 * Xanth to Sunder
 * Great Wise Tree to Yggdrasil
 * Bono to Jono
 * Breath of Fire IV has literally every NPC dragon, monster, and/or place-name rendered originally in Japanese kanji rendered in Korean hanja readings (in an EXTRAORDINARILY RARE Japanese-to-Korean example done in most international versions of Breath of Fire IV not using CJK script--including at least one case of what appears to be a rename of a monster to gratuitous Korean).
 * Babaderu to Bunyan
 * Master to Ershin (a rare English-to-Chinese example to preserve a Bilingual Bonus for a Meaningful Name that is a major plot spoiler)
 * Breath of Fire: Dragon Quarter limits it to groups rather than people, except for one mistake:
 * Dva to Dover (a misromanization of the russian word for 4, part of the game's Theme Naming)
 * Members to Regents
 * DBs to Genics

C

 * Cannon Dancer to Osman

 * Jennety to Mack the Knife
 * Hoover to Baby Head
 * Genocide to Scumocide
 * Blood to Boots (SNES port only)
 * Cardcaptor Sakura to Cardcaptors
 * Sakura Kinomoto to Sakura Avalon. They were originally going to rename Sakura "Nikki", but kept it as Sakura in response to protests. The dub still mispronounces her name by emphasizing the second syllable (sa-KU-ra) rather than the way the Japanese would say it (SA-kura).

 * Fujitaka to Aiden
 * Takashi to Zachary
 * Chiharu to Chelsea
 * Tomoyo to Madison

 * Jillbert to Greco
 * Gyadarun to Grobyc
 * Alf to Guile
 * Tsukoyomi (Harlequin) to Harle
 * Lutianna to Luccia
 * Mamacha to Macha
 * Marcella to Marcy
 * Mell to Mel

 * Ishito to Norris
 * Ocha to Orcha
 * Tumalu to Pip
 * Lazzuly to Razzly
 * Skarl to Skelly
 * Snakebone Master Jyakotu to Lord Viper (just "Viper" in the profile screens)
 * Spriggan to Sprigg
 * StarChild to Starky
 * Van Cliff to Van
 * Yamaneko to Lynx
 * One of the bosses, the Lunar Dragon, got mistranslated to Time Devourer (despite the Time Devourer actually being the next boss)
 * Chrono Trigger:
 * Chrono to Crono (due to space issues)
 * Maoh to Magus
 * Gash, Hash and Bosh to Melchior, Gaspar and Belthasar
 * Vinegar, Soysau and Mayonee to Ozzie, Slash and Flea
 * Marl to Marle
 * Marldia to Nadia
 * Granleon to Masamune
 * Contra
 * Private First Class Bill Rizer to Sergeant Bill "Mad Dog" Ko to Jimbo and back to Bill Rizer

 * Enemies from Super C (partial list, since not all the enemies had their names localized)
 * "Machine Gun Soldier" to "Alien in Sergeant Skin's Clothing" (human Mook)
 * "Violent Hextuble Mobile Cannon Spider" to "Babalu Destructoid Mechanism" (mecha spider sub-boss from Stage 3)
 * "Bone Fortified Anti-Gravity Ship Girararu" to "Krypto-Crustacean" (UFO boss from Stage 5)

 * "Mineralized Covered Beast Jameera" to "Jagger Froid's Spit Soldier" (spitting face statues from Stage 8)
 * "Ogre-Headed Beast Orlean" to "Red Falcon" (running alien mooks from Stage 8)
 * "Emperor/Uranian Devil Gava" is also sometimes called "Jagger Froid" (The Dragon according to the manual).
 * Enemies from Contra III (again, a partial list)
 * "Small-Fry Soldier" to "Corporals of Punishment" (blue and red enemy mooks)
 * "Man-faced dog" to "Man-faced mutt" (Exactly What It Says on the Tin)
 * "Sniper" to "Sniper" (the only enemy to keep the same exact name)
 * "Slave Beast Taka" to "Beast Kimkoh" (giant tortoise boss from Stage 1)

 * "Metal Alien" to "Vicious Slave Hawk" (flying alien boss from Super Contra)
 * Corpse Party
 * Tenjin Elementary School to "Heavenly Host Elementary"

D

 * Averted in Death Note. Contrary to what appears to be popular belief, in the English version Raito was not changed to Light. "Raito" is the Japanese pronunciation of the English word "Light", and "Light" is also the official romanization in Japan.
 * Played straight for a minor American character, Rally Connors, whose name was changed to Larry Connors.
 * Powerpuff Girls Z
 * Instead of having civilian names and hero names, the girls were referred to as "Blossom", "Bubbles" and "Buttercup" morphed and unmorphed, supposedly to better align it with the original series.
 * Although this makes little sense because the whole point of them having hero codenames was so that they could keep their superheroine identities secret (and not run the risk of being attacked at home or having their families attacked to get to them...)
 * Peach to Poochie
 * Snake to Ivy (which doesn't align with the original series at all)
 * PPGZ was set in Tokyo (a few actual landmarks, plus the general scenery and the use of Japanese signs everywhere). In the dub, it was switched to "New Townsville".
 * Villainess Princess Morbucks was stripped of her civilian identity too (in the Japanese, her civilian name was Himeko Shirogane).
 * Just about all other Japanese names were switched for English ones too. The boy who bullied Ken in the episode where her returns to school to make friends is given the name "Joey", and Blossom's sister is renamed from Kuriko to Kasey, among others.
 * Detective Conan to Case Closed (changed to avoid a lawsuit from DC Comics, who hold an ironclad trademark on the name "Conan" in all media forever—with a single exception—and aren't afraid to sue into oblivion anything else that shares the name)
 * Shinichi Kudo to Jimmy Kudo
 * Yukiko Kudo to Vivian Kudo
 * Yuusaku Kudo to Booker Kudo

 * Miyako to Kyo
 * Digimon Tamers (Non-North American English)
 * Takato to Tio (switched back after episode 1)
 * Hirokazu to Kyle
 * Juri to Jen
 * Digimon (note: in the case of the first season and the manga adaptation of the second season, the characters' original names were retained as their proper names, whilst their dub names were their nicknames.)
 * Taichi Yagami to "Tai" Kamiya
 * Yamato to "Matt"
 * Hikari to "Kari"

 * Krillin to Bongo
 * Launch to Marilynn
 * Tien to Shinto
 * Mercenary Tao to General Tao Pei
 * Korin to Whiskers the Wonder Cat
 * Master Shen to Lord Wu Zu
 * Shenron to Dragon God
 * More a case of Meaningful Name, as the Chinese "Shen-Long" actually means "Dragon God".
 * Penguin Village to Happy Valley
 * Dragon Ball (later dubs)
 * Tao Pai Pai to General Tao (DBZ)/Mercenary Tao (DB)
 * Mr. Satan to Hercule (though this was done as an edit, as American broadcast standards for kids' shows generally frown on religious references)
 * Genki Dama to Spirit Bomb
 * Dragon Slayer IV to Legacy of the Wizard
 * Dilgyos to Keela

E

 * Earthbound
 * Porky to Pokey (and back again in Super Smash Bros. Brawl)
 * Gyiyg to Giygas

 * PK Fighting Spirit to PSI Rockin (Ness's signature attack)

F

 * Final Fantasy II
 * Frioniel to Firion
 * Guy to Gus in the Origins release (future releases reverted to Guy)
 * Leonhart to Leon
 * Firion and Leon both came about due to character limitations in the game
 * Final Fantasy IV
 * Gilbert to Edward
 * Final Fantasy IX
 * Marilith to Maliris
 * Burimushi became Oglop
 * Final Fantasy VI
 * Tina to Terra (to keep it exotic)
 * Mash to Sabin
 * Cayenne to Cyan (space limitations)
 * Stragus to Strago (space limitations)
 * Realm to Relm (Significant in that her name is supposed to be pronounced like "real" with an "m" at the end.)

 * Pretty Cure
 * Nagisa Misumi to Nathalie Blackstone
 * Honoka Yukishiro to Hannah Whitehouse
 * Fu--un Mokushiroku to Savage Reign
 * Shishioh to King Lion and Real Shishioh to King Leo. King Lion is supposed to be a disguised stand-in for King Leo, but this nuance is lost due to the fact they have different names in the English version. This is also why the fake Shishioh is called "Shadow Shishioh" in later appearances.

G

 * Garou Densetsu to Fatal Fury
 * Marco Rodriguez to Khushnood Butt
 * Griffon Mask to Tizoc
 * Gash Bell
 * Gash to Zatch (which subsequently changes the title of the series)

 * Nobel Gundam/Noble Gundam
 * Gundam Heaven's Sword/Raven Gundam
 * Every name except Godot's was changed during the transition from Gyakuten Saiban (Turnabout Trials) to Ace Attorney. It even has its own page. The (Japanese) Takarazuka musical used the American names and setting rather than the original.
 * Special attention goes to Rou Shiryuu/Shi-Long Lang. Since he's from the Chinese-esque Zheng Fa the translators simply took used the Chinese reading of the kanji for his Japanese name and used that for his English name.

I

 * IGPX: Immortal Grand Prix
 * Takeshi Jinno to Takeshi Jin
 * Masa Ishikawa to Mark Ramsey

 * Sekkyou Oshou to Mad Monk
 * Kabuto Bushi to Samurai Guard

 * Y to Huey
 * Usohito to Slip
 * Nai Nai 043 to Nai-Nai

 * Pekoponian to Wussian
 * In the official dub, the only other characters whose names have been changed thus far are George Nakata, who became "the guy who was George Clooney's butt double in Michael Clayton and Batman and Robin" and Dasonu* Maso, who became the Dance* Master because the pun doesn't work at all in English.
 * KiKi KaiKai (Sequel First) to Pocky & Rocky
 * Sayo to Pocky
 * Manuke to Rocky
 * Miki to Becky
 * Takuan to Bomber Bob
 * Shinobi to Little Ninja
 * The Kirby anime: First the title: Hoshi no Kirby (often translated as Kirby of the Stars) to Kirby Right Back At Ya. Then:
 * The main areas. Pupu Village became Cappytown and Pupupuland became Dreamland. The latter is done in the games as well, and so the change of Pupu Village to Cappytown isn't too far-fetched either, considering the whole town is populated mostly by cappies!
 * Fumu to Tiff
 * Bun to Tuff
 * Escargon to Escargoon
 * Holy Nightmare Corporation to Nightmare Enterprises
 * Nightmare to eNeMeE (though occasionally the show still called him Nightmare)

 * Howard Lockwood to Foward Fughes

M

 * Macross to Robotech
 * Hikaru Ichijyo to Rick Hunter
 * Misa Hayase to Lisa Hayes
 * Hayao Kakizaki to Ben Dixon
 * Averted regarding Lin Minmei, most likely because she's shown returning to her home in Tokyo's Chinatown at one point in the series.
 * The spelling, however, is changed. Lin Minmei becomes Lynn Minmay (the anime uses both, in the same episode no less, but the latter is the official spelling). "Lin" to "Lynn" also applies to everyone in her family.
 * Magical Doropie to The Krion Conquest

 * Doropie to Francesca
 * Makaimura to Ghosts N Goblins

 * Kunio to Mr. K
 * Riki to Jack
 * Shinji to Joel
 * Misuzu to Kim
 * Sabu remained the same in the NES version, but in the Sega Master System version he was replaced by a new final boss named Lucas.

 * Oikake (Akabei) to Shadow (Blinky)
 * Machibuse (Pinky) to Speedy (Pinky)
 * Kimagure (Aosuke) to Bashful (Inky)
 * Otobuke (Guzuta) to Pokey (Clyde)

 * Parasyte had the Tokyo Pop translation do this:
 * Tamura Reiko to Tamara Rockford

 * The protagonist's Evil Hand is nicknamed Migi ("Righty"), but because the image was flipped, he became "Lefty" in the translation
 * Megami Ibunroku Persona: Be Your True Mind to Revelations: Persona

 * Yamaoka to Alfred
 * Takahisa Kandora to GUIDO "THE ROCK" SARDENIA
 * Shin Megami Tensei: Persona 4
 * Kuma to Teddie
 * Almost all the names in the Phantasy Star series had to be changed because of space allowance; in Japanese, it allowed four characters, but in English, that meant it only allowed four letters. Several jokes get around the fandom about how the people of Algo can't comprehend names longer than four letters long. However, some changes were not only unnecessary, they were confusing.
 * Alisa/Alyssa to Alis
 * Tylon/Tyrone to Odin
 * Lutz to Noah, which became an inconsistency in the fandom and has spawned decades-old arguments and theories over who the first Esper was.

 * Amia to Anna
 * Kane to Rhys
 * Lann to Thea
 * Lynn to Sari
 * Lane to Nial
 * Noin to Cris
 * Fuin to Adan
 * Ruin to Aron
 * Luna to Kara (a stunningly inappropriate name change, since the character is the princess of the moon)
 * Laia to Gwen (a more appropriate change, as there were three Laia's in the game; the first was a historic figure (Laya), the second was her sister (also Laya), and the third was the sister's daughter (Gwen).)

 * Bel/Belle/Bell/Beru to Bianca
 * Kenyan to Stephan
 * As for the franchise in general itself, most Pokémon names, too many to list here. Perhaps the best-known example of this trope.
 * The games now have their own page.

S

 * Sailor Moon was quite extensive across the original English dub (all handled by Optimum under several different licensors). Many carried over into the original Tokyopop/Mixx Entertainment manga release as well. For the sake of not converting this to an exhaustive list, this simply covers the main characters and a tiny number of supporting cast members. The more recent updated re-release by Kodansha Comics uses a different translation than the original Mixx release and uses Japanese names only.
 * Usagi to Serena
 * Mamoru Chiba to Darien Shields (the surname only appeared in the Mixx manga)
 * Prince Endymion to Prince Darien (and later King Endymion to "King of the Earth"). This one caused a Dub Induced Plot Hole in the anime.
 * Ami Mizuno to Amy Anderson (though "Mizuno" also appeared during the Cloverway run)
 * Rei to Raye
 * Makoto to Lita
 * Minako to Mina
 * Chibiusa/Sailor Chibi Moon to Rini/Sailor Mini Moon
 * Plus her Brainwashed and Crazy alter ego Black Lady became Wicked Lady, likely due to Unfortunate Implications
 * Setsuna to Trista
 * Michiru to Michelle
 * Haruka to Amara
 * Some dolls put out by Irwin Toys in Canada called Haruka "Corrinn" and Michiru "Nerissa", but these were released despite no dub of S at the time to accompany them. It's not known whether Di C would have actually used these names had they continued their license of the franchise into S, and when Cloverway took over, the characters had different names.
 * A single issue of the original SMILE run of Sailor Moon called Haruka "Alex Haruka" and Hotaru "Jenny", though they admitted this was a mistake and all future reprints, including in the now out-of-print Pocket Mixx collections, reverted to their Japanese names.
 * Naru Osaka to Molly Baker
 * Gurio Umino to Melvin
 * Yu-ichiro- to Chad
 * Shingo to Sammy
 * And that's just the main cast. Pretty much everything changed.
 * Saint Seiya to  Knights of the Zodiac
 * Deathmask to Mephisto
 * Saori to Princess Sienna
 * Science Ninja Team Gatchaman to Battle of the Planets (to G-Force to Eagle Riders to the Gatchaman '94 OVA dub):
 * Ken "The Eagle" Washio to Mark to Ace Goodheart to Hunter Harris to... Ken.
 * Joe "The Condor" Asakura to Jason to Dirk Daring (No relation) to Joe Thax to... Joe.
 * Jun "The Swan" to Princess to Agatha June to Kelly Jennar to June.
 * Jinpei "The Swallow" to Keyop to Pee-Wee to Mickey Dugan to Jimmy "The Falcon".
 * Ryu "The Owl" Nakanishi to Tiny Harper to Hoot Owl to Ollie Keeawani to Rocky.
 * Berg Katse to Zoltar to Galactor to Lukan to Solaris.
 * Dr. Kozaburo Nambu to Chief William Anderson to Dr. Brighthead to Thaddeus Keane to...Dr. Nambu.
 * Leader X to "The Great Spirit" to Computor to Cybercon to Lord Zortek.
 * Red Impulse to Colonel Cronus to Red Impulse again to Harley Harris to Red Spectre.
 * Director Anderson was referred to as President Kane in Battle of the Planets, while the G-Force dub writers couldn't decide if he was "Director Anderson" or "Commander Todd". "Anderson" was definitely retained in Saban's Eagle Riders and the OVA dub though.
 * The Galactor syndicate to Planet Spectra back to Galactor to Vorak and then Galactor again.
 * Eagle Riders provided its own slew of name changes to characters exclusive to Gatchaman II and Fighter, the most notable examples being:
 * Gel Sadra to Mallanox (along with a confusing gender change). Her true name was also changed.
 * Dr.Sylvie Pandora to Dr.Francine Aikens
 * Dr.Rafael to Professor Andro
 * Count Erun Egobossler was given the name Happy Boy. Because he "likes to laugh so much". Apparently the only alternative dub name would have been "Merry Man".
 * Shaman King
 * Manta to Morty
 * Ryu to Rio
 * Chocolove to Joco
 * Hao to Zeke
 * Horokeu Usui nicknamed Horohoro to Horohoro nicknamed Trey Racer
 * Shining in the Darkness
 * Mephisto to Dark Sol
 * The various dubs of the Slayers anime change the characters' names, but only phonetically. The oddest case is Amelia, whose name in the Japanese version frequently waivers between "Amelia" and "Ameria", and the kingdom of Saillune (in one of the openings, it can be seen rendered as "Sailoon") is renamed Seyruun. Also, Zelgadis and Xellos's names in Japanese were officially romanized with two s's (Zelgadiss and Xelloss). The former two names, and the "Saillune" spelling are used in the translations of the novels, but Amelia is always Amelia in all non-Japan media.
 * Sonic the Hedgehog
 * Dr. Eggman to Dr. Robotnik, and then back to Dr. Eggman (this still annoys a lot of old English-speaking Sonic fans who prefer the English name).
 * Yuji Naka explained in interviews that Dr. Ivo Robotnik is his real name and Dr. Eggman is a nickname, similarly to how Tails' real name is Miles Prower. This is pretty much confirmed by Sonic Adventure 2, which introduced Dr. Eggman's grandfather, Professor Gerald Robotnik, and cousin, Maria Robotnik.
 * Amy Rose to Princess Sally (only in the manual for Sonic the Hedgehog CD)
 * Space-Time Detective Genshi-Kun to Flint the Time Detective
 * Genshi to Flint Hammerhead
 * Dad-Tan to Rocky Hammerhead
 * Sora Yamato to Sara Goodman
 * Tokio Yamato to Tony Goodman
 * Kyoichiro Narugami to Merlock Holmes
 * Time Pilfer (T.P.) Lady to Petra Fina
 * Many Time shifters
 * Spartan X to Kung Fu Master (unless stated otherwise, all changes are found in the manuals for the home computer ports)
 * Sylvia to Princess Victoria
 * Strongman to The Giant Kicker or just The Giant (NES)
 * Black Magician to Lightning Magician
 * Star FOX:
 * Katarina to Katina
 * NUS 64 to ROB 64
 * Panther Caluroso to Panther Caroso
 * Andorf to Andross
 * Aparoid Mother to Aparoid Queen
 * Aparoid Factory to Aparoid Hatcher
 * Ash Bowman to Dash Bowman
 * Street Fighter
 * In Street Fighter II, one of the three new bosses was an obvious Mike Tyson pastiche named M. Bison, which could have led to a likeness infringement suit had the name been kept in the American version. Since the name tags were made of solid graphics instead of text, it was easier to just rotate the names of the three bosses than make up a new one for just one character. Fan communities (particularly in tournaments between Japanese and overseas players) have adopted a set of nicknames for those characters to avoid confusion.
 * M. Bison to Balrog (Boxer)
 * Balrog to Vega (Claw)
 * Vega to M. Bison (Dictator)
 * Nash to Charlie
 * Gouki to Akuma
 * Julia to Jane (Guile's wife)
 * Chris to Amy (Guile's daughter)
 * Super Mario Bros.
 * Koopa Daimao- (sometimes "Kuppa") to Bowser, King of the Koopas.
 * And by extension, Koopa Jr. to Bowser Jr. and Dark Koopa to Dark Bowser.
 * Princess Peach to Princess Toadstool (in early games only, of course. She started going by her original name starting with Super Mario 64.)
 * Oddly enough, one episode of Super Mario Bros Super Show has her refer to herself as "Princess P".
 * Kinopio, Kinopiko and Kinojii to Toad, Toadette and Toadsworth, respectively.
 * Rosetta to Rosalina
 * Kuribo to Goomba
 * Noko Noko to Koopa Troopa
 * Pata Pata to Paratroopa
 * Teresa to Boo
 * Kuristine to Goombella

 * Heiho- to Shy Guy
 * Pakkun Flower to Piranha Plant. Also, Boss Pakkun to Petey Piranha.
 * Catherine to Birdo
 * Jugem to Lakitu
 * Mamu to Wart, though he goes by his Japanese name in his Link's Awakening cameo.
 * Gerakowitz to Fawful
 * Count Noir to Count Bleck
 * Killer to Bullet Bill
 * Gesso- to Blooper
 * Puku Puku to Cheep-Cheep
 * Wanwan to Chain Chomp
 * Yossy to Yoshi (later Japanese versions used the American spelling)

T

 * Stan to Stahn (to ease correct pronounciation)
 * Lion to Leon (same reason as above)
 * Mighty Kongman to Bruiser Khang
 * Johnny Shiden to Karyl Sheeden
 * Woodrow to Garr
 * Tales of Eternia to Tales of Destiny II
 * Fog to Max
 * Tales of Hearts to its translation patch
 * Kohak to Amber. This also seeps in during the localized Tales of Graces f, where Kohak/Amber becomes a Bonus Boss, and her dubbed name is also Amber.
 * Hisui to Jadeite (the literal translation of Hisui would be 'Jade', but since there's another Jade...)
 * Tales of Symphonia
 * Refill to Raine
 * Genius to Genis
 * Regal Bryan to Regal Bryant (likely the original intention anyway)
 * A couple of other names were not so much changed as re-Romanized, to ease pronunciation:
 * Collet to Colette
 * Shihna to Sheena
 * Transformers: Car Robot was originally about a group of new Transformers. However, the English version, Transformers: Robots in Disguise, changed it so they were named after characters from the original series.

 * Masaya to Mark
 * Kish to Dren
 * Pai to Sardon
 * Tart to Tarb

V

 * Valis series
 * Cham to Char (Turbo CD version of Valis III only)
 * Glames to Ramses (Turbo CD version of Valis III only)
 * Yuko to Syd (Syd of Valis, in game only)

 * Aulbath to Rikuo
 * Lei-Lei to Hsien-Ko

 * Shutendoji to Anubis
 * Anubis to Cale
 * Rajura to Dais
 * Naaza to Sekhmet
 * Kaos to The Ancient
 * Nasuti Yagyu to Mia Koji
 * Jun to Yulie
 * Yotsuba&! doesn't do this much, but:
 * One time, when Miura was wearing a robot costume made of cardboard, Yotsuba asked what the robot's name was. Miura improvised a name based on the material. The ADV Manga translation gave it as "Cardbo", while the Yen Press translation gave it back its original Japanese name of "Danbo" (from danboro, the Japanese for corrugated cardboard).
 * Many names were changed in the localizations of Ys Book I and II and Ys III for the TurboGrafx-16 CD:
 * Dogi to Colin {I and II only}
 * Rea to Lair
 * Raba to Rasta
 * Banoa to Berniece
 * Roo to Quay (the gremlin-type creatures)
 * Gort to Dekka
 * Zava to Yetai
 * Felghana to Kenai
 * Galbalan to Demonicus
 * Ilvern to Alcaino
 * And many more
 * Yu-Gi-Oh!, and its various sequels: the manga release of the original series kept the Japanese names of everything except the cards (in order to make the connection to the real world cards clearer) and Pegasus due to a lack of coordination in the licensing. The GX manga release always used dub names for characters that appeared in the anime.
 * Yugi Mutou kept his name, but its pronunciation changed so his last name sounded like "Moto".
 * Katsuya Jonouchi to Joey Wheeler
 * Hiroto Honda to Tristan Taylor
 * Anzu Mazaki to Téa Gardner
 * Sugoroku Mutou to Solomon Moto
