Toepick's appearance is a green-skinned, ogre-like alien with a dark green metal cage helmet on his head. The metal helmet has two horns protruding from the sides of it. The cage's door has five bars, three of which are in the center of the door. It opens in two halves, the lock in the very center of the door staying on the right half. Connected to this cage is his armor, which wraps around his shoulders and goes halfway down his chest. The armor is connected to his pants by chains. His pants are a simple pair of black underpants, with a metal waistline matching the color of his armor. His arms are long and misshapen, with bulb shaped spikes coming out of them and his fingertips are pointy. He also has a visible belly button. The glow from his green eyes can be seen through his helmet's bars. Toepick's Omnitrix symbol is on the helmet's extension covering his chest with two green circuit-looking designs accompanying the Omnitrix symbol on both sides.
Toepick's face is so horrifying and hideous that, according to Derrick, no being in the known universe can look at it without adverse effects, including fear, sickness, or even madness that include another alien of the same species. This was first shown when Toepick showed his face to a Dwarf Star-charged Psyphon, who was so terrified that his whole body (even his armor) turned white, and he begged Toepick to leave him alone (in-between screams of terror).
Toepick is an alien mentioned by Ken Tennyson during the episode Ken 10. The only things known about this alien at this time was his name and the fact that it is a very "disgusting" alien, as said by Kenny. Also, Kenny said that Toepick "Even grosses me out". He was one of the 10 aliens on Kenny's Omnitrix, but Ben agreed to replace him with Grey Matter.
