The Mario collection from Turtle Beach is growing even more today. Following the controllers and headsets from Mar10 Day, more items are now on the way. These new additions highlight Rosalina and the Koopa Troop, which feels like perfect timing with the movie coming out soon.

Rosalina and Koopa Troop Controllers Join The Lineup

The first part of the news covers the new controllers. Turtle Beach is launching the Rematch Wireless RGB Gaming Controller in Rosalina and Koopa Troop designs. These work with the Nintendo Switch system. I like how the RGB lighting matches each character theme. You'll get 40 hours of battery life and TMR thumbsticks to help stop drift. There are also two back buttons you can map for your own play style. These are official products that work with both Nintendo Switch 2 and Nintendo Switch.

You can pre-order both controllers right now on the Turtle Beach website and at other retailers. They'll arrive in stores globally on May 4, 2026. The Koopa Troop controller features a collage with characters like Magikoopa and Hammer Bro. The Rosalina controller's much more peaceful. It uses teal and yellow stars to create a look that fits her space theme. These designs offer a look that reflects different parts of the Mario world for fans.

A New Glow In The Dark Case For Bowser Fans

Next, there's a new case for the Nintendo Switch system. It's the PlayTrek case with a Koopa Troop theme. I find the glow-in-the-dark design very cool because it shows Bowser and his minions in a bright way. The case uses a tough shell to keep your console safe. It's got space for game cards and a mesh pocket for your cords. This case hits stores on June 14, 2026.

I'm most excited for the Rosalina controller. We've been talking about The Super Mario Galaxy Movie lately. Having Rosalina join the lineup makes sense since Brie Larson's playing her in the movie. This controller's the perfect way to keep the movie celebrations going when it arrives on May 4. It's a great addition to the collection. It's also good to see Turtle Beach move past just Mario and Luigi. The Koopa Troop items also look sharp and remind me of the classic NES days.

As a reminder, the Mario and Luigi controllers and the Mario Star headset arrive in stores on March 30, 2026. Between the Mar10 Day news and these new items, there's a lot to pick from right now. It's a big year for Nintendo fans.
