He's best known as the Purple Dragon, though his full title—the Blaze Meteor Dragon—sounds way more dramatic. After his time as a Dragon King, he reincarnated as an Ultimate-Class Devil, which honestly is still pretty impressive. Fans often note that his most significant role in the series comes through training Issei in the mountains, where he pushed the guy to finally unlock his Balance Breaker. It's the kind of mentor moment that defines his character, even if he doesn't show up constantly throughout the story.
