Seems interesting. I had 2 main idea's for a character:

1) Young God. The idea was that when the 4th Host Celestial came to Earth to judge its worth, Gaea gave it a bunch of mortals to train to show their worth. One of them who's sent back to Earth decides to go into SWORD specifically because "It's a gods duty to protect their people." I kinda like the idea of a Celestial-tech infused human who is powerful, yes, but also arrogant, completely inexperienced and unaware of how he world actually works. Intelligence 20, Wisdom 5 type build.

2) Fallen from Grace. I kinda like the idea of playing a mutant or inhumanoid that lost their powers and is now looking to either return them or replace them with something more powerful. Potentially technology based or mutating themself. But pretty much a Neogenic Nightmare in the making. Still works for the team and is doing their best to help, but is still held back and will take the opportunity to gather samples or components to help themself.
