Capcom saw Fighter's History as, well, uncomfortably similar to their own Street Fighter II. Uncomfortably, infringingly similar. That's why, in 1994, Capcom filed a motion in a California district court to prevent Data East from distributing Fighter's History arcade machines. They were able to prove that SF2 was a significant influence on History by referring to Data East's design documents, which were rife with references to Capcom's work. They were unable to prove, however, that the characters had been copied directly, and thus lost the lawsuit. Capcom's loss (and, really, they only lost legal fees here, because nobody in their right mind bought or played Fighter's History instead of SF2) was our gain, as Data East released the SNES version of the game that same year. Data East was then free to continue the series, with Fighter's History: Mizoguchi Kiki Ippatsu! and Karnov's Revenge/Fighter's History Dynamite.

While not legally proven to be infringing, it is quite obvious in a subjective view that Street Fighter II was on the designers' minds during the development of this game. While SF2's characters were basically stereotypes, Fighter's History's characters were slightly remixed versions of those same stereotypes. Jean was Vega dressed as Guile, for example. Marstorius was Zangief with a shirt on. Mizoguchi was Ryu without a shirt on. The special moves were distinctly familiar, and even the music and (especially) the announcing suggested a close relationship with Capcom's flagship product.

Luckily, by sticking so close to the source material, Data East accomplished what most second-tier fighting games could not: decent controls. It was actually possible to play the game, pull off some special moves, and have a basically okay time, unlike something like Ranma 1/2 Hard Battle. Most people focus on the ripoff aspect, and miss that Fighter's History is a not-awful fighting game.

Fighter's History bests Street Fighter in a way that Street Fighter can never outdo, unless they buy the rights to Data East's characters like, uh, SNK has: Karnov. The bald, portly, fire-breathing Russian strongman who was something of a Data East mascot appeared as the final boss in this game, doing what he did best: breathing fire. He was outfitted in some desert headwear, presumably so the player would have something to knock off other than his pants. FH featured a system in which specific accessories could be knocked off of fighters after sufficient damage, triggering a dizzy.

Fighter's History, while a more enjoyable game, contrasts with Data East's first fighting game, 1984's Karate Champ. They innovated by publishing one of the earliest one-on-one side-view fighting games, which was also one of the first games developed by Technos. Flash forward nine years, and they're aping Capcom.
