Yob

The Yob is an obese anthropomorphic hippopotamus and bank robber from the Mootant Village district of New Tek City in the Special Zone. Like many villains in the Mootant Village, he frequently committed crimes around 10 o'clock, knowing that the local heroes, the Zed Monkeys, would be too busy performing "Hero Hour" (an hour every day in which they pose and flex their muscles) to stop him. However, he did not count on the intervention of Sonic the Hedgehog who, despite the Yob's claim that nothing could budge him, took the villain out with a single Spin Attack. He was then handed over to the New Tek City police and arrested.
