Jose runs Phantom Lord and takes the job seriously—you can spot him by the witch hat emblazoned with his guild's symbol. He's got this whole mystical aesthetic going with what looks like a pair of wings attached to him, though nobody's ever actually seen him use them in a fight.
His magic, called Shade, lets him summon ghost troopers that follow his commands like an army. He can also throw up waves of ghosts to hit opponents, which is pretty effective. What really defines Jose, though, is his beef with Fairy Tail. Before they showed up, Phantom Lord was the guild—untouchable. Now they're treated as equals, and Jose hates it. He genuinely sees Fairy Tail as upstarts who knocked his guild off its pedestal, and that kind of resentment has shaped how he runs things.
Power-wise, he's considered to be on par with Makarov, which speaks to how serious of a fighter he actually is.
