Hey, nifty. Someone else remembers Aero the Acrobat. Batty'll be so proud. :-)

I like the Katana one. Looks sorta like a slacker samurai. Gotta love the baggy pants.

Though I do agree with Radium about the animations... of course, I haven't done any animation work, meself, but yeah, you might want to reuse less and redraw each frame by hand. It'd give a more fluid motion to things, I think.

Loves the art, though. Spiffing. :-)
