Velcro is the first child of Hawkfang and Zipper and is the older sister of Katrena, however due to baby Katrena falling through a wormhole and taking 29 years to get back to the present Velcro is now younger then her younger sister.

Bit of background information on how I came up with the idea for Velcro as a character, my wife was looking through my art binder and saw how the Zipper had a sister named Button and she made a joke asking where the other sibling or relative was, named Velcro. Long story short here we are LOL
