In Streets of Rage 1, Galsia is the most versatile enemy. He has a full combo, throw infinite knifes at you, stab you, walk over you with a knife on his hands, attack you with pipes, baseball bats... attacks which don't even knock you down, so it can be comboed with other enemy attacks.... And to add to all this, he as some cool infinite combos too. He even refuses to die when falling from elevators... not before dropping a full combo on you!

Galsia is the ultimate enemy of the entire series. He even got his infinite back on Streets of Rage, 4 when he walks over you with a taser.
