Cartoon with Samurais

[Orihalcon]

As with many others on here, I registered here to pick the brains of anyone who might remember this cartoon I can't for the life of me remember the name of, and it's one episode i'm looking for in particular....

I don't remember much of it, other than there is this one guy who has some secret power that allows him to turn into a giant samurai dude "Something of Osiris", i can't remember exactly, anyway when he transforms he says something like "SEVEN SAMURAI", and he becomes this big bulky samurai dude...

In this particular episode one guy wants to be just like him and ends up becoming a bad guy temporarily, he steals the same power and calls himself "Crimson Samurai" or something and they battle, and in the end order is restored...

Anyone remember, or know what the name of the episode or cartoon is called?

Your help would be much appreciated
