OC Wang Hanmei aka "Frost Hammer"

One of the freshmen of the Superhero U Academy: Personality She doesn't just hold her ground; once she picks a direction, she barrels through—a literal headbutt of a personality. Blunt to a fault, she has zero patience for beat-around-the-bush pleasantries. Beneath the rough exterior lies a playful, mischievous edge, mostly coming out when she's goading someone into a fight she already knows she'll win. Powers She channels frost straight into her horns and knuckles, hardens it right at the point of impact, and turns standard charges into bone-crushing hits. She also slickens the ground with icy patches to control footwork. Her kit relies on high-speed gap-closing, backed by high superhuman strength and durability even for a mutant, that let her shrug off heavy blows. She isn't charging blindly either—her tactical sharp-mindedness ensures she only commits when she sees a genuine opening. Her trade-offs are average reaction time, standard agility, and no healing.
