Hydron

Hydron splashed onto the scene in Deadpool #0 in 1998, a creation of the legendary Joe Kelly and artist Yancey Labat right at the dawn of Deadpool's breakout era. With a catalog presence that stretches all the way to 2023, this Marvel curiosity has quietly persisted across a quarter century, surfacing in the chaotic, irreverent world where characters like Blind Al, Bucky, and even Ben Parker somehow share the same wild pages. Rare appearances make Hydron a genuine deep-cut discovery for the dedicated Deadpool completist — exactly the kind of obscure gem that makes digging through back issues so endlessly rewarding.
