Underwater, no one can hear you scream.
A monolithic menace. The diabolical combination of the 5 Seacons who comprise him. Master at undersea warfare. Few Autobots can outdistance him or escape his evil clutches. Destroys everything in his path with ghoulish glee. A troublemaker and malcontent. Rarely follows orders. Fellow Decepticons are unable to control him. Capable of creating colossal tidal waves over 300 feet high. Because of his incredible size, Piranacon's reflexes are impaired out of water. Armed with the Seacons' entire arsenal of firepower.
(Presumably the line that Piranacon is comprised of "5" Seacons is a typo.)
