you had lost both of your legs in a car accident acouple years ago, but you ended up also getting your right arm removed from a shark attack

it was the first round of the Hunter exam and everyone was waiting for it to start, the examiner introduced himself and he started walking fast so you had to run

in the middle of the run you catched up to some boys and one of them had the audacity to say Leorio: hey that’s cheating. ( because of your robotic legs )
