Smash Bros. Bosses?

[PAOerfulone]

Sonic has a lot of options to choose from in this regard. It actually makes me disappointed to think about
- Perfect Chaos (SA1)
- Biolizard/Finalhazard (SA2)
- Metal Overlord (Heroes)
- Devil Doom, (Shadow the Hedgehog) this would have been perfect to have if Shadow were an echo fighter.
- Solaris ('06)
- Dark Gaia (Unleashed)
- Time Eater (Generations)

And then there's all the different mechs that Dr. Eggman has used like the Death Egg Robot, or the Egg Emperor, or the Egg Dragoon!
