Now here's a final-boss-worthy Sonic toy – Destructoid
The Eggman Robot Battle Set from Jakks Pacific It’s rare for me to want to mention honest-to-goodness toys here, particularly the stuff that Jakks Pacific puts out, but I’ll make an eggception for this Eggman Robot Battle Set based on Sonic the Hedgehog 2. It’s so cool. I mean it. You’ve got to see it in action. As much as an advertisement for a children’s product is going to do everything in its power to make the toy seem fun as hell, I really do like the idea of launching a curled-up Sonic with a catapult, nailing the boss three times in the chest, and watching it crumble.
