The Energon Z Beam is a weapon used by the resurrected Trypticon during his tenure surving serving as one Violen Jygar's Nine Great Demon Generals. When engaged, the weapon unleashes a burst of red energy from the mechanical sauropod's mouth. It is presumably composed of pure Energon Z.
The weapon proved extremely powerful, and nearly killed Sonic Bomber when Trypticon used it on him. However, when he was preparing to fire again, Dai Atlas unleashed the Zodiac energy, which allowed him to kill Trypticon before before he could attack again.
