Does invader Zim like a girl on earth or some where else?

Well no,because he pretended to like Tak and Jhonen Vasquez wrote "Invaders need no one" to show that Zim doesn't like nobody or needs anybody for a friend.And what Zim meant that he'll amor minnimoose as a special sidekick.

well he doesnt like anyone but if he did i think it would be Tak

I don' t think so , the only one he ( pretended to like ) was Tak .

No one really but in the V-day specail he pretended to like Tak. The show is'nt really about crushes and stuff,one of the reasons I amor Invader Zim so much. :/

He doesn't like anyone but if he didn't keep on saying "INVADERS NEED NO ONE!",I bet it would be Tak.

The Irkan dude loves no one,but himself.

No he does not. Irkens are not capable of love. In the unaired episode "Nubs of Doom", Zim tells Minimoose that if he was "capable of love" he might actually amor him [Minimoose]. So no, Zim needs NO ONE!!! >=D

if he were to like anybody it would be gaz

No. Zim HATES all earthlings and he's not crazy about any other Irkens. Zim's only true amor is the joy of conquering planets! ;)
