Brilliant Dynamites Neon

The leader of the Bad Lads Gang. While he is a thug, he is also an excellent tactician, charismatic leader and a man of honor. He holds skill and dedication in high regard, respecting Kite for the effectiveness in disarming the sand steamer Flourish, one of the helmsmen of the Flourish for his willingness to sacrifice himself for the ship, and Vash for his skill... Period. He hires Kite to coordinate an attack on the Flourish. BDN quickly figures out that Vash is using Kite and the old communication tubes to maneuver through the steamer, and uses this to set up an ambush, which Meryl and Millie step in to defend Vash. The attack culminates in an old fashioned duel between Vash and himself to decide whether or not the Flourish will be saved. In the battle, one of his dynamos are destroyed, and Vash opens a previous wound with his usual acrobatics. BDN considers the fight over, likely realizing the condition he’d be in if Vash hadn’t already been wounded, and withdraws. He even goes so far as to sacrifice his own transport to stop the Flourish from going off Enora cliff.

Trivia
He uses phrases like "shines" and "flashy" a lot.

It's hinted that he had family in July when it was destroyed.

BDN is last seen in the final chapter of volume 14, where he sees Vash on the TV.
