1. In a sea of Infinite possibilities of futures, there were always be a future were he never dies.
2. He can only change his fate, the futures that he is involved with.
3. If he is killed before he uses his "Almighty" he can't revive himself.
4. His future sight only works on who he is gazing at, his ability to change the future does not.
5. He can reality warp a future event, and teleport it to the present. This however is limited by what i mention in the number 2, above.
6. Seriously guys, why is this not in his profile? It would make our lives a lot easier.
Edit:
7. Objects broken by his Almighty in all futures cannot be rejected (with something similar to Casuality Manipulation,
[1]) to their original state. Unless, someone inserts or changes the past of certain object.
