Rival

Rival is Rob's... eh... rival. Rival hopelessly competes against Rob when he does weird things, often doing something similar, but to a more extreme degree. He has Lackey help him with this and together they become two times more weird than Rob is. Rob could really care less, which only serves to annoy Rival further. Rival likes to speak in an overly villainous way, monologuing like there's no tomorrow. No one knows Rival's real name or identity.

Lackey

Lackey is Rival's... lackey. Original names, I know. Lackey has a snake tongue and hardly ever speaks. Like Rival, no one knows Lackey's true identity.
