Leviacon

Leviacon is large Cybertronian inhabitant of Aquatron who resembles an Earth whale in his Alternate Mode.

History
Like the rest of Aquatron's inhabitants, Leviacon was enslaved by the Quintessons when they conquered Aquatron, and forced to serve their monstrous whims. He was later freed due to events incident to the arrival of the Ark and Nemesis at the planet, and joined Optimus Prime in his campaign to defeat Curator Inquirata and liberate the planet. They eventually succeeded, and Leviacon returned Optimus to his comrades, assuring them that the Aquatronians would be safe on their reclaimed homeworld.
