The Primal Hero.

As the title may suggest. Izuku is from a different timeline, a timeline ranging back to the dinosaurs. Izuku will be wearing a dinosaur head kind like how Hanzo wears his wolf thingy. Izuku will be transported into the future after killing a t-rex with his hands. (To survive he has to be strong,). Upon arriving at the new timeline, Izuku is met with an unexpected sight. In front of him were smaller animals than he thought could exist. He was indeed in a forest. Luckily for him, though the forest isn't that far away from UA so when there were rumours about someone roaming in the forest, killing wolfs, bears and more animals, UA decide to form a team to capture the person. I hope you enjoy.
