Let’s imagine that the TARDIS appears in Zim’s universe, in a different Earth than the one he usually visits. It’s safe to say that the Doctor would notice Zim’s attempts at conquering Earth and would try to stop him.

  It’s even very likely that Dib would become a temporary companion to the Doctor and tell him all the information he’s gathered about Zim so far! So who would win?

  Honestly, this one is fun to think of, but doesn’t require that much thought to draw a conclusion on. While Zim’s technology is impressive and would in theory be advanced enough to go up against the Doctor, the truth is that the little green guy has failed at conquering Earth countless times already. Now imagine if the Doctor stepped in. Odds are that after stopping Zim, the Time Lord would go after the Irken Empire next to stop them from conquering more planets! And honestly, I wouldn’t want to be part of the Irken Empire when that would happen…

WINNER: THE DOCTOR!
