Zach is the son of two parents whom are both obsessed with aliens. According to Lincoln, Zach lives between a circus and a freeway.
Not much known is about him so far, aside from the fact that he is one of Lincoln's best friends. He's shown to be a nerdy kid who isn't very social and is interested in sci-fi, especially aliens as shown in "Zach Attack."
Zach is a short kid with wild unkempt red hair, glasses, buck teeth, and freckles on his cheeks. He wears a white and blue striped polo shirt, blue jeans, and white sneakers.
