Gunpei Yokoi
Nintendo followed with the release of the Game Boy Pocket, a smaller version of the original Game Boy, designed by Gunpei Yokoi as a parting gift. A week after the release of the Game Boy Pocket, Gunpei resigned from his position at Nintendo. Gunpei helped in the creation of a competitor system named the WonderSwan, using the skills he gained in the creation of the Game Boy.
