Swat Kats: The Radical Squadron

Mayor Manx and his associate Mr. Young are planning to build an industrial park on the tropical paradise of Anakata Island. One of the islanders (voiced by Clyde Kusatsu) warns Manx that if the island's sacred stone is destroyed, bad things will happen. The stone is crushed by a bulldozer and an enormous rock monster named Volcanus (voiced by Frank Welker) erupts from the island's volcano, freed from his 1,000-year lava prison. The SWAT Kats' weapons are ineffective against his rock body and must resort to finding a weak spot in the rock to destroy Volcanus before he attacks Megakat Nuclear Power Plant and decimates the city.
