Nega-Pneumatica is a giant robot created by the government.


When the Superior Squad and heroes from other universes thought they were in the negative universe, they were attacked by Nega-Pneumatica. The heroes teamed up to defeat her before trying to go back to their own universe. However, Nega-Pneumatica wasn't defeated yet and went back for the heroes again. They then knocked off Nega-Pneumatica's head, which crushed Glowy, killing him. They then went back to their own universe, only to find it was all a trick with holograms and technology.

The heroes then worked out that it was a government plan to keep them distracted, but didn't know why.
