Death Egg Robot (Sonic The Hedgehog 2) The original Sonic The Hedgehog’s final boss was kind of a dud, with Dr Robotnik eschewing any sort of mech for a bunch of pistons to crush Sonic with.

Of course, this means you'll be forced to learn some new mechanics ... Youll also use it in the final boss, a bit like how Sonic becomes Super Sonic in the final boss of his own story.
