Hi! I'm back after a long break. I won't be on as much due to Skool, but I will try to post when I can.
Anyway, this is my headcannon post. Here is where I will post any theories and other non-cannon ideas about the show. I will post when I think of some, so check back often!
1. Irkens DO have a sense of love, just like the other emotions they have. However, because it is unneeded, it is often looked down upon. Invaders and other types of soldiers are raised and trained not to have emotions like love because it may distract them from their mission. Some don't even know there is an emotion like, "love", while others can't forget and are often reprimanded. (This is supported by the fact that, even though he didn't actually like Tak, Zim at least tried to act like it, and seemed to have a sense of what a "boyfriend" should act like.)
2. Dib and Bigfoot are friends.
3. The Pig-Lord and Gaz still keep in touch and are close friends.
evilgyrl! Changelings and Irkens LOVE INVADING!!! Only I believe, ponies/humans can become Irkens/Changelings! The ones who have became CAN'T change back (to their original form). Read Inkrose98's Shapeless Sun, Celesita becomes a Changeling. The both can invade. Queen Chrysalis was a pony that wanted power and changing power. What if an Irken's pak/ a changeling's cocoon turns the user with the power. Only the cocoon change can stay as long as the queen wants, but an Irken's pak makes the human (The user) become acting like an irken. Irken without pak loses power. We must be mind readers!
