[M/N] or Smeetary worker [M/N] is sent down to earth with Zim, he was the one that raised Zim after all so it's technically his fault for how Zim is. That was his punishment, not that he minded. His favorite Smeet has always been Zim, despite his loud personality.

Just another reader insert thing i'm embarrassing myself with. I do not own Invader Zim. All characters and canon scripted lines go to Jhonen Vasquez and the writers. I'm merely a huge fan writing this fanfiction and spreading my love for this show.
