Ekko is an inventor and a leader of the Firelights. He is aggressive and battle-hardened from all the harships he has had. His good friend and boss when he worked at a pawn shop was killed in front of him when he was a kid. He also lost most of his friends when he was young. His face is serious and stonehearted. He is tall and lean, but his arms and biceps are very muscular. He stops at nothing to gain his freedom.
