Broly's strength and speed increase dramatically when he's mad. When he loses control, Broly transforms into his Legendary Super Saiyan form. In this state, his muscles bulge, his hair turns greenish-yellow, and his eyes become white and blank, indicating his berserk nature. Broly's rage is often triggered by traumatic memories or intense emotions. This rage drives him to attack relentlessly, often without regard for strategy or his own well-being. His ki blasts and attacks become more powerful.
