Barret is the leader of a cell of the eco-terrorist group Avalanche, trying to prevent Shinra Electric Power Company from using mako, the life source of the planet, as a form of energy. Barret fights passionately for his cause to protect the planet. He cares greatly for his allies, motivating them with powerful speeches, while also himself fighting on the front lines of his cell's operations. His seemingly benevolent cause of fighting for the planet is a cover for his personal vendetta and anger, which he later must come to terms with. Despite his brash and sometimes violent attitude, Barret has a good heart, and is torn between fighting and caring for his daughter, Marlene.
