Colt Grice

Koruto (コルト) is an Eldian warrior working for the Marley government and is the older brother of Falco. He is also a candidate to inherit the Beast Titan power.

Appearance
Colt is a physically fit young man with light eyes and short light hair. Like his fellow warrior cadets, he wears 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 is different from that of the Marleyans in that the shirt collar has a small badge with the Eldian star instead of a small clip and the hat has a white stripe with the Eldian star on it  instead of a pure black stripe. As is law in Marley, Colt also wears the Eldian armband as all his family and ancestors residing there do as well.

Personality
Colt is a dedicated and brave soldier, risking his life to go retrieve his wounded brother Falco after he is attacked. He shows great care for his brother as he gives him his hard hat as they flee and makes sure his wounds are treated when they return to the hiding trench. While caring and brave, Colt is also a tactical soldier who works with his Commander to plan their attacks, despite his superior officers looking down on him for being an Eldian. Colt always appears to have a guess of what moves might be made in advance by the enemy and tries to strategize to use their forces and Titan powers to best take out the threat without losing lives.

Story
During the Marleyan war with the Mid-East Allied Forces, Colt is present among 800+ other Eldians fighting on behalf of Marley. However, he is valued as a warrior cadet with the potential to inherit the Beast Titan power. During the fight, Falco and some of his comrades are hit by enemy fire, killing some but sparing Falco and leaving him wounded. Colt appears to save him and puts his hard hat on Falco's head before carrying him on his back while avoiding enemy fire. When Colt returns to the hiding trench with his wounded brother, their fellow cadets tend to his wounds. Commander Magath shows concern for Colt's well being but then demeans him when he reports that they are unable to dig any further due to enemy fire. Colt continues to speak with Magath and voices concerns over the enemies artillery, saying the should let Galliard and Pieck handle the enemy gunmen, but is denied. The appearance of the anti-Titan artillery leads Commander Magath to order his 800 Eldian warriors into battle to take it out, but before this can happen the plan is cancelled in favor of Gabi's idea to solo attack it with a bomb. Colt watches as Gabi executes her attack and succeeds. When she is under fire from one remaining survivor, Falco rushes out of the trench to save her, much to Colts concern. Luckily, the two are both saved by the transformation of Galliard and the last enemy gunmen is taken out.

Relationships

 * Falco - Colt is Falco's older brother and cares deeply for him, as he threw himself into the battlefield to rescue his injured brother, even giving him his hardhat as they fled.


 * Magath - While Commander Magath may look down on Colt for being an Eldian, he values him as a soldier and showed concern for his well-being when he risked his life to save his brother. Colt appears to show some margin of respect for this man, as he attempts to work through strategies with him and is not above giving his opinion of the best move.
