He has large yellow eyes with black pupils, outlined with black lines. His skin is colored dark magenta and quite wrinkled. He has blue, egg-shaped armor and light blue metallic extremities. His claws are also blue.
Toby has a twin brother, Kyle Monitor, who is a starliner captain. Toby feels that Kyle looks down on him for being a lowly hover-bus driver.
In Return to Forever, he was giving a tour to humans after they learned about Undertown. However, they were attacked by Sweet-Eels Sparklefunk and Tummyhead. He was saved by Rath and Rook almost immediately, but his bus got wrecked by Rath. Later, Jimmy Jones asked if he knew anything about a person he saw in the crowd. Instead of answering Toby only said "Take off or I'm gonna get a rock and a melon baller and I'll have monkey brains for lunch".
