Okay this is going to be crazy but since I looked up pairing pics of these two and read fanfics I'm kinda curious now.
This may sound weird but...I really wanna do an Invader Zim, Zim/Gir rp. And before you say anything Gir is gonna be human this time and Zim is still an alien but taller and with a little muscle. Since Gir has become human, he's still his same self mentally and talks the same he just looks human with silver hair and blue eyes. Zim is having a hard time fighting his feelings for Gir, they have been on planet Earth for 5 years now and Zim has given up on world domination.
Zim and Dib have become friends and Dib is now in college (Zim dropped the whole school act 3 years ago) and visits Zim and Gir often and he is beginning to notice Zim has been acting different around Gir and tries to convince him to tell him. (I'll be playing both Gir and Dib.)
