Yie Ar Kung-Fu

Yie Ar Kung-Fu was released in 1985 by Konami and is the second Fighting Game ever (after Karate Champ). It pioneered many aspects now familiar in fighting games including health bars, opponents of various fighting styles, and female fighters.

Tropes used in Yie Ar Kung-Fu include:

Acrofatic: Buchu.
Action Girl: Star and Fan are the first in Fighting Game history.
Bilingual Bonus: A voice (Oolong?) says "xiè xiè" ("thank you" in Chinese) upon getting an extra life. Buchu says "nǐ hǎo" ("hello" in Chinese) when he receives a Groin Attack. "Yie Ar" from the title is Chinese for "one two".
Boss Game: In the first, only Oolong is selectable. On the GBA version, you can be all of the bosses in multiplayer.
The Computer Is a Cheating Bastard: The CPU is notorious for having the opponent just avoid Oolong's attacks and get in two or three hits before the player can react.
The Computer Shall Taunt You: Nuncha will randomly twirl his nunchucks and strike a pose, leaving him open to attack. To a lesser extent, Pole always twirls his staff above his head before going into an attack sequence, but he will move of the player tries to attack.
Dual Tonfas: Tonfan.
Everybody Was Kung-Fu Fighting: With actual kung fu and Chinese weapons, to boot.
Fighting with Chucks: Nuncha.
Groin Attack: Any attack that hits Buchu's crotch causes his eyes to bug out and he says "nǐ hǎo".
Hit and Run Tactics: How nearly every opponent fights.
Me's a Crowd: Feedle is actually a bunch of the same fighter attacking in succession.
Mirror Boss: Blues uses the same fighting style as Oolong.
My Kung Fu Is Stronger Than Yours: Oolong vs. Blues.
Not Quite Flight: Oolong and Buchu.
Paper Fan of Doom: Fan.
- Improbable Use of a Weapon: She constantly uses her fans as projectiles.
Set Swords to Stun: Sword's, er, sword doesn't kill Oolong, it just merely knocks him out.
Simple Staff: Pole.
Theme Naming: Opponents are usually named after the weapon he/she uses. In fact, the only exceptions are the unarmed fighters: Oolong, Buchu, Feedle and Blues.
Variable-Length Chain: Chain.
"Wake-Up Call" Boss: Nuncha is the first opponent to pose a real challenge.
