|Assignment||To conquer/destroy Earth (Completed)|
|Notable facts||Unlike his present self, Emperor Zim actually conquers the Earth.|
|First appearance||Issue 12|
Emperor Zim was a future counterpart of the present Zim that succeeded in taking over the Earth. In this future, Emperor Zim made the Earth into his image, with monuments and paintings of him everywhere on Earth. His first, and so far only, appearance was in Issue 12.
Emperor Zim wore a purple gown and large, crown-like hat, along with a dark goatee. He was fairly taller than the present Zim, though it was revealed that this was the result of high heels. After conquering Earth, he resided inside a giant mansion shaped like his head, and upgraded GIR (now GIRT), the Roboparents, and his gnome robots.
After taking over the Earth, Emperor Zim planned to use the Planetary Scary Fast Drive located in Australia to send the Earth straight to his future's Almighty Tallests Red and Purple. However, the present Zim from the past interfered with his plans after realizing his future self was actually a big jerk rather than a kind benefactor. Present Dib teamed up with present Zim in order to stop Emperor Zim's plans, mostly because present Zim attached a machine to Dib's head that shocks any wearer who disobeys Zim.
While at the Planetdrive Control Center in Australia, the base of the Scary Fast Drive, present Zim and Emperor Zim struggle, ending in Zim kicking his future self into the hole made by the Scary Fast Drive in Austalia to rocket boost the Earth, presumably killing him.
- While Emperor Zim hasn't actually shown up since Issue 12, Zim's "Burrito King" outfit in Issue 18 has been noted to be quite similar in overall appearance.
