What will happen if two Irken Invaders land on Earth on a Mission to recover a crashed Irken Scout Ship? Who will join them on their Mission to total Planetary Domination? And who will stand against them? Irken flying saucers annihilating entire Citys. Humanity getting infiltrated by an Alien Empire. Load your Disintegrator Ray. Activate your Arsenal. And... ...prepare the Mothership. Your time has come... Invader (Y/N). (Invader Zim belongs to Jhonen Vasquez, Destroy all Humans belongs to THQNordic, You belong to yourself)

When Dib's plans of spending Summer break spying on Zim is crushed by his dad sending him away to a small town called Gravity Falls he soon discovers his dad unknowingly sent him to a place Dib could only dream of. Dib meet's Mabel and Dipper during his stay and immediately becomes fast friends with the Mystery Twins. But it dosen't take long for a certain Irken to get bored without Dib back home that the Irken soon decides to take his own trip to Gravity Falls. I'm going through a huge Invader Zim and Gravity Falls phase rn so I thought why not make a crossover of the two shows. (DISCLAIMER) I don't own either of these amazing shows
