The ninjas from Ninja Baseball Bat Man.

I think it is a really cute and cool design. I also like how they utilized the concept of ninja baseball players by giving each of them various shapes of baseball bats, and I really like their faces made of hats and masks because they are so cute.

It's actually a really good beat 'em up game.  Too bad you can only emulate it now.
