Mr. Flice Guy was the main antagonist of Sonic: Flice of the Living Dead. He is voiced by Frank Welker.

We first catch sight of Mr. Flice Guy when Freddy Harrison and his son Jerry Harrison play piano until they hear a roar. Jerry rushes into the forest. When he looks, a shadow appears at the bottom of him. Jerry looks up at a giant figure with four insect arms, revealing it to be the shadow of Mr. Flice Guy, who frightens him off. Jerry runs away as Mr. Flice Guy runs after him. Jerry goes in Harry's campervan and tells his dad that he saw Mr. Flice Guy. Harry hugs his son and tells him that Mr. Flice Guy was a monster.
