The planetary annihilator is a weapon of mass destruction in spite of its relatively manageable size. Members of the League of Robots have been known to wield such weapons in duels, [TBwaBB] which are extremely destructive. It fires an intense energy beam that instantly incinerates anything it touches and increases in diameter as it travels further.
