Ickis dont have a brother, Gromble in disguise make a drink that make Ickis throw up eggs and these eggs hatched 5 clones of him with different personalities .
I finally found content of my hyperfixation I'm so happy 😭😭 I love this omfg this and the edited "five faces of Ickis" are driving my life force rn thank you so much 😭
Another tip is to search up "invader zim drawing angles" scroll around for a while till you find him looking different ways It will prob also show his movie version and his show version i use this a every now and then
