Idea №19 Borderlands x Worm

The vault hunters defeated both Handsome Jack and The Warrior, but when the forcefield that was protecting both Jack and Lilith shut down, Jack, instead of monologuing and letting the filthy barbarians kill him, gathered whatever resolve and strength he had left and rushed to the damaged vault gate, jumping into it at the same time as the stray bullets and other projectiles fired by tired vault hunters completely destroyed it. Something goes wrong during his transfer to the vault because of the destroyed gate, and instead of being trapped in an empty vault for the rest of his life he finds himself half-dead, losing both his blood and his mind, on the streets of Brockton Bay instead. This is by far the worst day of Jack's life. He triggers and gains a Tinker power that allows him to recreate and improve most of the Borderlands technology. He is a changed man now that he lost absolutely everything. What will he do? Will he use this second chance to become an actual hero? Or will he try to take control of another Warrior and destroy this world too? Nobody knows that yet, not even himself. What we know for certain is that Jack's existence will cause some big changes.
