Arthur Boyle

Arthur Boyle is a Third Generation pyrokinetic and a member of Special Fire Force Company 8 in Fire Force. He's a young man with shaggy blonde hair, blue eyes (with distinctive white pupils), and a lean, muscular build.

He has a delusional, over-the-top personality where he genuinely believes he's a legendary knight (self-proclaimed "Knight King"). This leads to him acting arrogant, refusing to use honorifics with anyone, treating women like princesses, and living by a chivalric code. Despite often coming across as dim-witted or an "idiot," his straightforward mindset and unshakable confidence make him surprisingly effective in battle.

His main ability involves generating a powerful plasma blade called Excalibur from a sword hilt he carries, which he wields masterfully to cut through nearly anything. He has a long-standing rivalry with Shinra Kusakabe from their academy days. Overall, Arthur combines comic relief with genuine strength and heroic (if delusional) spirit.
