Gashat Gear is a fictional device from the Japanese tokusatsu series Kamen Rider Ex-Aid. It is used by the main character, Emu Hojo, to transform into the superhero Kamen Rider Ex-Aid. The Gashat Gear resembles a video game cartridge and is essential for activating various game-themed powers and abilities during battles against enemies known as Bugsters. Each Gashat Gear represents a different game, allowing the user to access unique skills and forms. The device is inserted into a Gashat holder, which is part of the transformation belt called the Ex-Aid Driver. This innovative concept combines gaming elements with traditional superhero themes, appealing to fans of both genres.
