The secret weapon.
powerful // confident // magical
From a minicomic I made in 2011 called Fantasy Baseball, Fireball is the secret weapon every opposing team fears: he is the flamethrowing star closer of the Dragons baseball team (rivals, of course, to the hated Knights)!
Summoned by an arcane sequence of runes (baseball scoring notation), chanting ("Take Me Out to the Ballgame"), and ritual (The Wave), Fireball appears on the pitching mound to bail out his team when they need him most. Is it cheating? No, it's just Fantasy Baseball.
