Well, it was mentioned that the Tallest assigned Zim to work for the Darkstar Council. And as you all know, Zim is 100% loyal to the Tallest, despite the fact that he doesn't know that his invasion mission is a fraud.
Yeah, but like I said, Zim disobeys the Tallest a LOT when he doesn't feel like doing what he's been told to. He just deludes himself into thinking they were "just kidding," or something. He escaped from Foodcourtia twice after being banished there, he participated in Impending Doom I despite being told not to directly by the Tallest (heck, he didn't even delude himself there, he just flat-out disobeyed). That might be why he's a "defective" (almost all Irkens are stupid, so that's not why). If he were ordered to help non-Irkens conquer the world, he would probably laugh at the "joke" and then go off to build an army of evil robot mimes.
And Zim in the show can be pretty mean in a wacky Jhonen Vasquez way; he rips out children's organs and tortures people, and stuff. I remember someone here saying once that Zim just wouldn't be part of a team, and I'm starting to agree, that's all. Actually, Tak would be a better choice because she's more focused, etc. But I think the Tallest wouldn't send real help to any other species. They try to destroy/enslave everyone else, not help them. They were probably just trying to get rid of Zim.
The Tallest don't really respect Tak's genius yet, either. They're not good at recognizing competent Irkens. They shot the first Irken to conquer a planet in OID II into said planet because he was "too fat" (and short...and ugly). They're big jerks who just want to eat donuts all day.
Anyway, I realize I have way too much geeky knowledge of the IZ series, so I'm way
too picky about characterization. I should definitely just relax. =P It's not a big deal. But other people got to whine about Blossom, so this was just some friendly nitpicking...mmm, yeah.
Oooh, something shiny. *runs off after it*
