He is a very good pilot.
DarthStorm is part of the Storms crew. Despite the fact that he was able to obtain his Storm name, he preferred to stay on the attack aircraft (he wears this symbol on his shoulder). His role is to fly fighter planes, sometimes even bombers. He has a certain character, he is not like all the Storms, he is much more positive and seems to like what he does. We could even consider him as a neutral character rather than a villain, but he works likewise on the side of the villains…
When he first trained as a pilot, he met Shik, at that time he was also undergoing his pilot training. And so these two became close friends, so even when Shik left the Storms, Dart still helped him (moment from Rinna episode 19).
