Bandai Namco has released the Season 17 trailer for My Hero Ultra Rumble, confirming Mirko as the new playable character arriving with the season’s launch. My Hero Ultra Rumble Season 17 goes live on May 27, 2026.
Mirko is the headline addition, but the official Season 17 promotion lists two further confirmed updates: a new Battle Style for Present Mic and a new outfit for Mt. Lady. Those additions sit alongside the season’s expected events, license rewards, and rolling cosmetic updates, though Bandai Namco has not detailed every My Hero Ultra Rumble Season 17 reward in the trailer.
For players who haven’t been following the game closely, My Hero Ultra Rumble is a free-to-play 24-player battle royale based on the My Hero Academia anime. Teams form up and fight to be the last squad standing, with Bandai Namco regularly introducing new characters and cosmetics each season. The game is available on PlayStation, Xbox, Nintendo Switch, and PC via Steam.
Season 17’s timing follows the game’s established pattern. Season 16 launched on March 25, 2026, with Star and Stripe as its new playable character. Bandai Namco’s original roadmap described each season as lasting approximately two months and introducing a new playable character, alongside events, Battle Pass content, and limited costumes. Several Season 16 rolls and events were scheduled to end on May 27, making the move into Season 17 line up with the game’s usual seasonal cadence.
Community discussion following the trailer has touched on other possible additions, including speculation around Aizawa, but those details have not been confirmed through official Bandai Namco channels. The confirmed Season 17 additions remain Mirko, Present Mic’s new Battle Style, and Mt. Lady’s new outfit until official patch notes say otherwise.
