The Attribute Slider is a device that change a person's attributes and increase their strength, charisma, dexterity, and intelligence at the cost at another attribute. The users appearance changes with it such as gaining a muscular body with strength and a giant brain with intelligence. As shown in the episode "Wet Kuat Amortican Summer", the device can have dangerous adverse effects towards its user if not used correctly, as Summer and Morty fuse together with the latter becoming a Kuato attached to her after the two fall into a pool and get electrocuted due to the device.
