One-Punch Man Joins Crystal of Atlan in Limited-Time Crossover

---

The worlds of anime and magicpunk collide starting today as Crystal of Atlan launches its first ever crossover with One-Punch Man. This limited time event, titled “Boom! One-Punch KO!”, is now live across iOS, Android, PC and PlayStation 5. It brings iconic characters like Saitama, Terrible Tornado and Boros straight into the action-packed world of Atlan.

Face Boros, Unlock Skins and Dive Into Heroic Events

The main event, Path to Hero, lets you take on the powerful alien Boros in an exclusive boss battle. Defeating him earns you the Mark of the Dominator, which can be traded for rare crossover rewards. You can also unlock Saitama’s transformation item, a Master’s License, avatar frames and more by participating in the crossover challenges.

Terrible Tornado joins the game as an S-grade support pet, using psychic powers to control the battlefield. Two themed mount paints are also available, Sky Knight – Genos α and Windride Skateboard – Hellish Blizzard β.

The event is also paving the way for the arrival of Mystrix, a new subclass of the Musketeer, debuting on July 10. She fights with a transforming Weapon Case that turns into shotguns, sniper rifles, floating cannons and even a motorcycle. As she deals damage and switches weapons, she builds up to a devastating Charged Pistol attack.

Crystal of Atlan is a free-to-play magicpunk MMO Action RPG that first launched in May 2025 and quickly became a top download in several regions. The crossover is available now for a limited time, so don’t miss your chance to fight alongside Saitama and face Boros head-on.
