Marvel vs Capcom 2/Silver Samurai
Silver Samurai, AKA Kenuichio Harada, is a sometimes foe sometimes friend of the X-Men, and Wolverine in particular. He is the Oyabun of Clan Yashida and is a skilled samurai. His mutant power is a tachyon field which in particular he uses to enhance his sword.
For the purposes of MvC2, his best assets are decent health, great chip damage, and one of the best supers in the game.
First row: LP, HP, A1. Second row: LK, HK, A2.
There's no clear choice of which of Sword Slashes or Shuriken to use. Shuriken is better for a few teams. Sword Slashes is very very useful for rushdown, as he's out there poking at them for a bit: it's a ghetto Spiral-Y. The only reason to pick Y-type is for the team super, but that's just a waste.

Generally you're going to want to poke and build meter. If you can, throw out shurikens to chip them down. Your best weapon is Raimei Ken: learn to combo into it. Works well off of any antiair assists or off of his launchers. You can combo it off of sFP too, but cFP is a better link.
Sword powerups are generally a way to get yourself killed. It is usually a good idea to switch out if you accidentally activate his Honoo/Fire powerup. If you get a lot of levels and want to show off, use Koori/Ice.
The same sword powerup can be stacked up to three times. As you stack, the applied nerfs decrease, giving you just the benefits at 3x. 3x Ice also gives you Hyper Armor. Using a different sword powerup cancels all previous effects and uses the new effects.
Be wary of accidentally activating sword powerups: smart players will be floating over your head trying to cross you up.
Odd stuff: He can't be thrown while crouching. He also is hard to unblockable.
There's a nice throw loop in the corner that kills people dead.
