Lumi

Lumi is a mythical fighter with moderate health, long range, and potentially high damage. She attacks by throwing maces at her opponents and commanding them to fly back to her. For her super, she creates three circular explosive areas with increasing size and damage. Enemies hit by the largest explosive area are temporarily stunned, but can still attack. Her first gadget, Hit the Lights, leaves a burning area on the ground around her maces, burning enemies if they touch it. Her second gadget, Sinister and Frosty, creates an ice area that slows enemies and makes maneuvering difficult. Her first star power, 42% Burned, causes her super to leave a burning area on the ground, temporarily burning enemies if they touch or remain in the fire-affected area. Her second star power, Halftime, causes her attack to temporarily slow enemies when the maces return.
Lumi is the drummer in her band.
From her name, her accent, and especially her lines in Finnish, we know that Lumi is Finnish.
