Hyperion

Short idea.

Handsome jack is reborn into marvel with all the tech knowledge from the borderlands franchise and make his company again.

Doesn't have to be marvel, could be dc if you want. Or another route you can go is Star Wars, he is reborn on a small human planet and takes over or what ever you can think of.

He could also be reborn in mass effect, that could be pretty cool. If you want it to be a si then you can have your character be reborn as jack in borderlands first but they still die for whatever reason you think of and then are reborn again in a world of your choice.

As always have fun with it.
