Tummyhead is a villain in Omniverse.
Tummyhead is a multi-color skinned bipedal alien. He has two heads on one body. He wears blue overalls. He appears to have been stitched together, as some of his skin is a different color than the rest of his skin. He also has screws and stitches placed in random spots on his body.
Tummyhead is pink with yellow eyes and red pupils.
Dummyhead is tan with black eyes and pink pupils.
Tummyhead's upper head (Dummyhead) has a dim-witted and childlike personality while his lower head (Tummyhead) is smarter and more mature.
He made a cameo in Rad.
He was seen in Return to Forever in Undertown where he and Sweet-Eels Sparklefunk attempted to rob humans in a tour bus. However, Ben and Rook appeared and Sweet-Eels and Tummyhead were forced to fight. Tummyhead fought Rath but was eventually defeated by him, while Sweet-Eels was defeated by Rook.
In Mud Is Thicker Than Water, along with Sweet-Eels and Liam (who was later revealed to be Lucy Mann), he was chased by Ben and Patelliday for stealing Plumber weapons. He got his weapons taken away by XLR8. Later, along with the other members of Psyphon's gang, he received highly advanced Plumber Tech from an uncovered Gorvan. However, at the end, he and the others were defeated and arrested for their actions.
He made a cameo in Something Zombozo This Way Comes.
In Universe vs. Tennyson, he watched Ben's trial.
