Ball² first appeared in Fallout New Vegas Mods: Wasteland Thrash -Part 1 and was the product of a glitch where Ballarms was accidentally "cloned" when Al entered the Reactory Hideout for a review of Wasteland Thrash.
Al was confused that there were two Ballarms in the house and accused Ballarms of building another Ballarms while Al was away. Ball² kept following Al and he was annoyed at his presence. Al lost him in Boulder City and was glad that happened.
- Al assumed Ball² was German because of the locations added by Wasteland Thrash was partially in German.
- Al can differentiate Ball² from Ballarms because the former doesn't speak.
- At one point, he has lived under AlChestBreach Headquarters before Al actually moved in. He had a pod under the building that was surrounded by small flames on the floor. In FNV Mods: Liberty Reloaded & The Canyons Have Eyes - 1, Al reviewed the house mod and came across the pod. He immediately panicked and went on with the video in fear that Ball² might show up.
- He is similar to Scratch as they are both clones of another companion, in this case being Ballarms instead of Skitters.
