Izuku Grenore - The Paradoxical child

Izuku Grenore. Bullied. Mother, status: Deceased (Loved). Father, status: Deceased (Hated).

All Izuku wanted was to see his mother again, he starts to experiment. First, he creates his support items called Dynamo at age 4. Next, he experiments with time travel. He achieves his goal of time travel by age 10. However, after traveling back multiple times, Izuku quickly realizes that he is incapable of going back to his own past. He completely breaks from this realization and goes insane. After aimlessly wandering through time, Izuku feels himself starting to disintegrate. He returns to his original world and does one final, forbidden, experiment. This disintegrates him to molecular levels then ties his very being to the essence of Time and Space. Now an ageless nihilistic god of time and space stuck in a 15 year old's body, Izuku goes to UA, trying to find happiness from the one last thing his mother wanted him to do.
