Caleb Grit is the son of Ace Grit and Mira Fermin. He is a Subterra brawler partnered with Magma Wilda, and is the leader of the Vestal Division.
Caleb is a 15 year old Vestal boy. He has pale blue-green hair that reaches the middle of his neck, and narrow, blue eyes.
Allie and Caleb are twins, and aside from appearances, share a few personality traits. Both are cocky and prideful, and have full faith in their abilities. Both are also immensely stubborn, and refuse to go down without a fight, or at least a semblance of one.
However, where Allie is hot-headed and reckless, Caleb is calm and analytical. Though he is not shy in the slightest, he is still shyer than his sister (who has a big mouth), and is often the one to calm her down when she needs to be calmed. He also thinks about the consequences of his actions, even if he performs something spur-of-the-moment.
While Caleb is a talented brawler and enjoys brawling, he has a disdain for fighting among the brawlers themselves. He is often the mediator when fights break out.
