One of the techie herose note some strarnge readings from Trapjaw, that seem to indicate he’s not acting of his own free will as a lackey of Skeletor.
They capture Trapjaw and try to fix him despite his protestations. It ends awfully. He breaks out going out a rampage that requires Skeletor and He-Man to work together.
In the end, its revealed that Trapjaw works for Skeletor out of gratitude because he restored his free will. One day while Skeletor was casually warping through dimensions looking for things that might be useful, he (literaly) ran into Trapjaw as he was acting as a one-man army in a gang war at the behest of his criminal masters.
Skeletor manages to win and gets Trapjaw repaired after investigating what the heck that was all about.
He-Mans friends apologize and Trapjaw accepts it mostly out of wanting to forget it happened than any sincere acceptance.
Now I’m of the opinion He-man shouldn’t get any darker than that one Psychonauts level, so most the violence in the flashback is implied with fire and screams.
And it works with giving him lots of wacky accessories. He designs lots of weird non-lethal weapon attatchments as a way to try and escape his past.
