This is a rare and unusual item by Tomy Toys. The "Sonic Duel" top launcher set. You don't see many of these around. 

The figures appear scrunched so that the tops will still balance, their pose has to be this way. Sonic is clearly early, as they hadn't decided yet just how his spikes should be. If you look at the second photo it also proves that Eggman can spin on his head as well as on his base!
