The Chakra Hero: Deku

Izuku won't originally be from My Hero Academia and instead will originally be in Naruto. Izuku Midoriya spent his entire life training, not a day would go by where he hadn't trained. He was able to rival Rock Lee in terms of physical prowess and even trained the same way. Just because Izuku worked on his physical fitness doesn't mean his chakra is weak, in fact he had one of the strongest chakra's out there. He was easily able to control all elements of Chakra and eventually stole a Sharingan for one eye (Like Kakashi Hatake). Izuku was no pushover. He destroyed those who stood in his way and trying to stop him from achieving his dream. His intelligence was also nothing to scoff at. He was on the same level of intelligence as Shikamaru Nara. He wasn't a peoples person and always wore a mask.
