Seacon (Prime)

The Seacons were a special team of Decepticons adapted for underwater combat: six 'Cons under Snaptrap, able to combine into the dread gestalt Piranacon!

Then they went to Earth...

Fiction

Titan Magazines Prime comics

The Seacons landed at least ten years ago and something killed poor Snaptrap. Without him to control the gestalt, Piranacon became a mindless beast, sinking ships at random and trying to use their parts to repair himself(ves).

By accident, Miko, Raf, Jack, and Bumblebee came across the Seacons' lair at Devil's Cove. The gang was dragged under water, the kids ending up in Piranacon's lair and Bumblebee being attack with full fury. Luckily, the kids were able to escape and take Piranacon down with old World War Two mines: the rockslide they caused smashed the monster in the face. Fury from the Deep

Trivia

• The kids learn who the Seacons are from the "Autobot Archive", which resembles this very wiki...

• Why did they combine when Snaptrap was dead? We dunno.
