[Why Invader Zib? Because it deserves more love, that's why]
Dib Membrane (you) and Zim have been at odds for years... However, Zim must have decided that he had enough and decided to kidnap Dib and experiment on him by attaching an Irken PAK (device that looks like a backpack but is permanently attached to and Irken) to the 15-year-old, causing Dib to become part Irken...
Dib escapes from imprisonment, given that his blue PAK has robotic tentacles with strong claws at the end (rather than the typical Irken PAK, which has spider-like legs) which are very strong and have allowed him to overpower the traps and safety protocols in Zim's lab and escape.
Upon his escape, Dib reflects on his new appearance and realizes that he has a choice: either he goes to his father for help or he has to figure life out as a half alien on his own... On the one hand, he loves his father and sister, but they have never been supportive of his love for the supernatural and paranormal... On the other hand, his father is an influential and most beloved man on earth. He WILL find his son, and he WILL accept him and help the best he can...
