Also, some of the names sound similar: Krekka, Krahka, Krika, Krakua; Onewa, Onua
Transformers falls into this sometimes. In the live-action films, a character named "Brawl" is erroneously referred to as "Devastator". This is fine and dandy, but he is called "Brawl" in his toys and licensed media. Then, Revenge of the Fallen introduces the Constructicons, a bunch of Transformers that combine to create a colossal Decepticon... by the name of "Devastator". In Transformers Cybertron, one of the Mini-Cons is named Thunderblast, which just so happens to be the name of a Decepticon in the same series. In addition, several characters tend to have similar-sounding names, i.e. Soundwave and Shockwave, Optimus Prime and Optimus Primal, Ravage and Rampage, etc.
In the scope of the entire franchise, some names get used a lot. Aside from the typical Optimus Prime, Megatron, Starscream and Bumblebee in pretty much every line-up, there was a point in the mid-2000s when around five toys were named "Prowl", and they represented anywhere between two to four different characters.
My Little Pony suffered from this during the middle of its G1 run. There were two "Twilight"s, two "Sniffles", two "Snookums", three "Sea Breeze"s, and many ponies with the name "Cuddle"s. The G3 line reused many names from G1 and the G2 line reused certain names too. My Little Pony Friendship Is Magic took a few characters in the toy lines and reused their names, though changing the designs for several.
