IZ Zombie AU

okay, lets get into this shit. Zim accidentally brought a disease from Irk that basically caused a mass pandemic, and eventually caused the zombie apocalypse. Dib, Gaz, and Gir teamed up, since Zim was basically patient zero, Zim was locked up in his basement. Of course, Zim still has his mind and thought process, but his brainpower is decreased, so his grammar, motor functions, and logic is weakened and he has a need to eat flesh. Gaz stepped up and basically has been leading Dib and Gir through the apocalypse. Dib has been depressed, barely surviving, and is just trying to keep Gir out of trouble. Gir is mostly oblivious to the danger, since he's a robot and completely immune. The apocalypse has been going on for about a year now, Dib is 14, Gaz is 13, Zim is 14, and Gir is a little kid (he has no defined age, so idk what to put). you play as Zim. Story: so, its been a year since the apocalypse started. today, Dib decided it was time to try and let you out after Gir has been begging for weeks to be able to see you. he has a full on leash and muzzle ready, so that you won't infect anyone.
