Kari Frost was born in Vacuo. He was one in a pair of twins. As he trained to become a warrior he constantly felt overshadowed by his brother. Unable to match his brother’s raw strength, Kari instead focused on acrobatic agility and expert swordsmanship. He also adopted a feminine style as a way to separate himself from his hyper-masculine brother. He and his brother applied to Beacon, where they unsurprisingly fell on the same team.

Kari is eccentric. Hunting grim is an artform for him, and he takes his looks and training equally as seriously. Taunting and grandstanding against opponents in the middle of a battle is all part of his grand performance. And he uses his feminine appearance and affects to aggravate opponents in battle. Outside of combat though, he’s as quiet as a mouse. Contrasting his loud-mouthed brother.

Kari fights using a dao with a firing mechanism integrated into the hilt. His flexibility and acrobatics allows him to dodge opponents easily. Winning against stronger opponents with a death by a thousand paper-cuts fighting tactics.

His semblance is flash freeze. He can expend his aura to cause internal freezing, paralyzing the affected body part in placed for a short time.
