(I updated it because I figured out stuff)

Val is an Irken Invader. She was pretty short when she was first assigned to planet Vegeta. Once she got there, it wasn't there! So, she decided to other stuff. After 5 years, she finally left, conquering a lot of other planets in Irks name. She'd invented something that could make her taller. Once she reported into the Tallest on her conquers, it was rather late at night. The tallest were already asleep and weren't paying attention to her. She wanted to stop Zim's mission because she just didn't like Zim. Zim was always mean to her in the acadamy. Val only told the tallest that she wanted to get rid of him, but she wanted to keep him alive and make him suffer on Earth.
A couple of days after that, she arrived on Earth. She stole a family, brainwashed them, and kept them locked away, only to show them when she needed to. She went to the school after creating a fabulous disguise, a peach skin color suit and mask, contacts, and a wig. She also included a different style of clothes. With this, Dib didn't notice her. Ms. Bitters placed her next to Dib and Zim (she moved Zim to Brian's old spot). She already gave hints that she hates Zim. Zim also hates her. However, Dib likes her. And so, you have to read the comic to find out what happens... then agian, i also have to finnish it all :p
