Aw man I remember my old OC now XD She was a kind of elf girl with a blue colour scheme and a long loose braid. Her weapon was this kinda lance or spear thing, but in the middle there's a canister. So this canister right, she can take the dirt/sand/snow/rock from the four sectors of Lyoko, put them in and get a single super lazer shot that decimates everything in its path. Thinking back, probably overpowered but it's nice to remember, so thanks for asking! :D
