Axel

"My show now, Keyblade master! Who am I? Oh, my name's Axel. Got it memorized?"

—Axel

Axel, the Flurry of Dancing Flames (おどる火の風, Odoru Hi no Kaze), is the Nobody of Lea, and is Rank VIII within Organization XIII. He wields fire and enchants his weapons, twin chakrams, with his pyrokinesis to unleash powerful rapid attacks. The Assassin Nobodies are under his control.

In Kingdom Hearts: Chain of Memories, Axel was the trump card for the rest of the Organization as a double agent in Castle Oblivion  to keep track of Marluxia's plans. In Kingdom Hearts II, Axel betrayed the Organization for his friendship with Roxas and acted of his own accord to try and help Sora, though he originally wanted to turn Sora into a Heartless to get Roxas back. Axel appears in Kingdom Hearts 358/2 Days as a playable character and makes a cameo in a cutscene in Kingdom Hearts Birth by Sleep.

Lea, his complete being's original name, was revealed in the Day 356 Secret Report and also mentioned by Saix. Lea had a connection to Saïx's original persona, Isa. Both Lea and Isa appear in Kingdom Hearts Birth by Sleep.
