Mirko Joins the Roster in My Hero Ultra Rumble Season 17
Bandai Namco has kicked off Season 17 of My Hero Ultra Rumble, and the headline addition is exactly the one fans have been hoping for: Rumi Usagiyama, better known as the Rabbit Hero Mirko, is now a fully playable character in the free-to-play hero battle royale.
One of the most popular Pro Heroes from My Hero Academia, Mirko's leg-driven combat style is a natural fit for Ultra Rumble's fast, vertical skirmishes, giving close-range players a powerful new pick to learn.
What's New This Season
Alongside Mirko's debut, the publisher confirms that Season 17 layers in fresh seasonal content for returning players:
- New playable hero: Mirko, the Rabbit Hero
- Exclusive costumes tied to the season
- Special in-game events running through the season window
Platforms and Availability
My Hero Ultra Rumble remains free to play on PlayStation, Xbox, Nintendo Switch and PC via Steam, and Season 17 is rolling out globally to all supported platforms. Bandai Namco has not detailed India-specific event timings or regional pricing for the season's premium cosmetics.
Worth Logging In For
If you've drifted away from Ultra Rumble, a new character launch is traditionally the best time to jump back in — Mirko's release is paired with login-friendly events and limited-time costumes, so squad up early before the meta settles.
