Battle Fighters Garou Densetsu

There's a lot of similarities between these two franchises, from the original games alone, in these adaptations is basically that 2 protagonists want revenge from the villain, who happens to be a charismatic one who sometimes steals the spotlight to the heroes, there's a lot of fights, but it all leads up to the final boss fights which the best one, just to name a few. 

They are both fighting animes. 

Both are adaptations of famous fighting games. 

Both are from fighting games but I think the Fatal Fury series is done better than Street Fighter II V.
