Though he looks like
him, Rasetsumaru is not Haohmaru or
related to him in any way. In reality, he is a bloodthirsty
demon from the dark world of Makai, opened up by Amakusa many years earlier.
He learns about the existence of Haohmaru, a so-called skilled warrior
who looks like him. Calling him a copycat, he now searches for him
to kill him.
Shodown 5 Special, Samurai Shodown 6, Card Fighters Clash
did it, so what not Haohmaru? You know, they could've just called him Evil
I really don't know what to make of this design... on one hand, it's cool to see
a "demon Haohmaru," an interesting design in some ways. But of course,
he's still a sprite clone at the end of the day, and of course shares a lot of
Haohmaru's moves. :/
