When it comes to combiners, most suffer from the same problem: an inability to agree on anything while in their super-robot form, resulting in limited intelligence and limited effectiveness. Such is not the case with Piranacon. The Seacons who compose Piranacon can all agree on one thing, they love to hunt. In fact, they love it so much, that once they combine, they absolutely will not stop until they've either run out of energy or are destroyed. This has gotten to be such a problem that their commander, Snaptrap, has been forced to activate an automatic timer upon combination, forcing Piranacon to disassemble after a period of time. Despite this one set-back, Megatron considers Piranacon an ideal warrior and wishes he had more Decepticons like him.
Piranacon is the combined form of:
- Snaptrap (leader) - torso
- Nautilator - right arm
- Overbite - Jawbreaker cannon
- Seawing - left arm
- Skalor - right leg
- Tentakil - left leg
Shockwave sent the Seacons to attack Galvatron when the future Decepticon neared the Decepticons' island base and threatened his position as Decepticon leader. When the six warriors failed to put a dent in Galvatron, they combined into Piranacon and renewed their attack. Even in this massive form, after a long and brutal underwater battle, Galvatron defeated them. Blasted into their component parts, the Seacons were abandoned where they fell. |Enemy Action|
The Seacons later took part in a major offensive against the Autobots on Earth's moon. The Seacons formed Piranacon, joining his fellow combiners against the Autobots' combiners. The Decepticons were forced to retreat, however, when Grimlock and Blaster joined the battle. |Totaled|
Soon after their island base was relocated to the Arctic, Piranacon's might was called upon again. A mysterious starship had entered their airspace, and this potentially hostile action had to be answered with a show of strength. Piranacon assembled and grappled the edge of the starship as it landed, but he was called off when Starscream announced that these were no intruders, but a second group of Decepticons led by Scorponok come to visit. Piranacon set the starship gently on the ground. |Cold War|
