People die. Sometimes though they're not quite ready to do so yet and strike a deal with a higher power to escape their fate - be it by being rescued against all odds or actually dying, but coming back. In addition, their deal includes some kind of Power-Up: They come back as more than they were before.
It doesn't matter if the dying person asked for the rescue and/or their new powers. They may get just what they need to finish off whoever caused their death in the first place, or they may be Blessed with Suck or Cursed with Awesome. Maybe their new powers really aren't worth the price, but in some way, they got an upgrade.
This can happen anywhere in a story, or maybe it's just the backstory of a character. The resurrected may be a hero or a villain (but rarely neither). They may turn against the higher entity that saved them, but just as often they follow them loyally.
Can involve Reforged into a Minion and/or a job to be done by the now resurrected guy, but doesn't necessarily have to. An Emergency Transformation and/or Working for a Body Upgrade may or may not be involved.

- A heroic example occurs in The Book of Life, where Manolo sought death at the hands of Xibalba to spend eternity with Maria.
