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 before his death.
Colt was a physically fit, tall young man with long face, light hazel eyes and short light brown hair. Like his fellow Warrior candidates, he wore the standard Marleyan soldier uniform consisting of a light jacket and pants, supply packs on the hip, suspender straps, a hard hat with a stripe around it, and tall combat boots. As an Eldian, his uniform was different from that of the Marleyans, as his shirt collar has a small badge of the Eldian star instead of a small clip and his helmet has the same star with a brightly colored stripe instead of a pure black stripe. As is law in Marley, Colt also wore an Eldian armband as all his family and ancestors residing there did.
Colt was a dedicated and brave soldier, risking his life to go retrieve his wounded brother Falco Grice after he came under enemy fire. He showed great care for his brother as he gave him his hard hat as they fled and made sure his wounds were treated when they returned to the hiding trench. 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. Colt always appeared to have a guess of what moves might be made in advance by the enemy and tried to strategize to use their forces and the power of the Titans to take out the threat without losing lives.
