Prototype is a blocky, doll-like robot with a white casing. He is seemingly unfinished, with exposed mechanical elements on their right arm, legs and back of the head. He has blueish-purple eyes with a hot pink highlight.
Prototype has four horns: two sets on his head (yellow on the left, red on the right) and two flatter ones (purple on the left, blue on the right) on his lower jaw. Prototype has four-clawlike fingers on each hand, with the "thumb" being red and the rest yellow, blue and purple

Car is a silly sentient feline creature who is capable of speech and thought. He possesses the basic silly features of a cat but does not walk, more so just slides across the ground on all fours.

Car, while usually appearing without them, does possess some form of silly eye pupils in the form of white silly streaks. He also seems to glitch out/have his silly vessel malformed on occasion as seen in stuff like "Car's Little Song".
Car is depicted as a joyous, whimsical and silly.
