Each version of the game has a costume called the Launcher with a themed design unique to each console, though all variants of them perform the same ability of shooting bullets while standing still:

• Star Launcher is exclusive to the Nintendo Switch version and is red akin to the Nintendo logo. Its bullets feature star effects, likely in reference to the Mario series.
• Blue Launcher is exclusive to the PlayStation 4 and PlayStation 5 versions and visually resembles a PS5 console. Its bullets feature effects with the PlayStation face button symbols.
• X Launcher is exclusive to the Xbox One and Xbox Series X|S versions and prominently features the Xbox logo. Its bullets feature green X's similar to the Xbox logo.
• Steam Launcher is exclusive to the PC/Windows version and features a large red valve on its back, in reference to Steam's creator Valve. Its bullets are also valve shaped.

Each version's Launcher costume was originally unlocked if save data from the game's demo was detected, but since the demo is no longer downloadable, the costumes can now only be unlocked by inputting a specific code on the title screen: L, R, L, R, L, L, R, R, Up, Down. The official Balan Wonderworld Twitter account initially posted a hint for players to figure out the code themselves, which could be solved by identifying which costume is found in the applicable world number.
