Bowser vs. Shadow

Shadow

Don't try to put me in the shadows I'll jump on you then kick your shell into a Goomba,

Before my first game there was more curiosity to me than an 8-bit King Koopa,

Before you hear it I'll make you lose all your rings and remake the extinction of the large reptiles,

I don't need a blue shell-hedgehog to knock you off the road I'm a life-sized projectile,

They call me Shadow because I'm faster than light and I tend to kill the president,

Bowser
 * He was in Super Smash Bros yet  Shadow only managed Super Smash Flash
 * Shadow hovers on shoes
 * Shadow hairs on his chest look like
