Garth is a moody one, just like his mom, Gaz. 🤭

Either Zim is his father, or a relative, like a uncle or something. He will never say though.

part of the D.P.D, (Dib police department of course) , he and his assistant are the ones who brought our Dib to the D.P.D for protection. Even though he is not a Dib, he is his nephew which counts, right?

Despite being maximum moody, he still has a good heart. And that good heart is saving our Zim from execution. Something that would make any Dib squirm.

his human disguise has a sick Mohawk because of course!
