The Phoenix is basically an immortal being who shows up throughout human history in Osamu Tezuka's stories, usually to help characters fulfill their destinies. It's got seemingly unlimited power and a soft spot for the people it encounters.
Based on the mythological fire bird, The Phoenix can resurrect itself from flames, heal others, and even grant immortality to those it cares about. Fans often note how its abilities seem almost boundless—it's less about following rules and more about doing what's needed in the moment.
What's wild is the scope of its existence. The Phoenix hasn't just witnessed human history; it's been around for all of it, and apparently for the evolution of every species too. Some interpretations suggest it's even been present for Earth's rise and fall across multiple cycles, possibly even larger cosmic events. It's the kind of character that makes you realize Tezuka was thinking on a genuinely epic scale.
