The Brotherly Heroes: Deku&Luffy

Izuku Midoriya and Alex Midoriya Twin Brothers, both quirkless, both with dreams of becoming heroes. One day when Alex was 5 him and Izuku got lost in the woods Alex found a fruit he took a bite out of it to see if it was safe to eat and give to his brother. It was so he went back to Izuku and as he was walking to him, he fell flat on his face when he looked to see why he was all stretchy like rubber. After a hour or so he was able to stay stable and walk again. When he got to Izuku he was a little beaten up. After that he became stronger and trained his newly found quirk. While Izuku stayed quirkless.
