Colt Grice was an Eldian living in Marley and the older brother of Falco Grice. He was a Warrior candidate who was selected to be the next wielder of the Beast Titan power. While caring and brave, Colt was also a tactical soldier who worked with his Commander to plan their attacks, despite his superior officers looking down on him for being an Eldian. However, he lacked discretion in times of leisure, having Pieck Finger share her alcoholic drink, despite being very bad at handling liquor.
