Midoriya Izuku has lost all hope to become a Hero. After having his dreams of Heroism crushed by All Might, Izuku returns home that afternoon to decide what he should go after this time, in terms of dreams. Everyone and everything had done all they could in order to destroy his chances at becoming a Hero. But there was also another thing he loved aside from Heroes. Dinosaurs. His father gives him a call, stating that Izuku will be able to see some of the animals on Isla Sorna. All he needs to do is fly over to the island itself and he'd meet his son there in order to show him around. Izuku, being extremely excited at the chance of seeing Dinosaurs in their natural habitat takes the chance. He isn't aware that this is a trap set by his father, nor the fact that he will not be able to return back to the mainland until around a decade afterwards. Upon arriving above Isla Sorna, the plane he took to fly there suffers an engine failure. It crashes lands on the island before Izuku is left upon it with no way of returning back to the mainland. After 10 years of living on the island, he has long since forgotten his name, his identity and how to show himself to others in a formal way.
