In Japan, the Seacons of Beast Wars Second resemble the original Seacons in Super God-Masterforce, but are in different color schemes. The Japanese equivalent of Nautilator is not a member of this group, and the character corresponding to Tentakil is female. Their members (along with their North American counterparts in italics) are: Halfshell (Snaptrap, leader, robot/snapping turtle), Scylla (Tentikill, robot/squid) Coelagon (Skalor, robot/fish), Terramander (Seawing, robot/manta-ray), Sea Phantom (Overbite, robot/shark). They can all merge into God Neptune (Piranacon, robot), who was armed with a sword.
Lioconvoy sent Scuba and Diver to go see who owned the ship that splashed down. Going under they were met by Scylla who was very interested in them, but the two escaped. Halfshell then went up using Tasmania Kid's fishing line. A fight soon started between Halfshell and the Cybertrons. Scuba and Diver were ordered to return to sea. During the fight, the Cybertrons knocked Halfshell on his back and hit him with all their firepower. When Halfshell seemed dead, all of a sudden he came back to life and started spinning around very rapidly.
The Cybertrons soon continued fighting but then Halfshell called his fellow Seacons, and they merged into God Neptune. The Cybertrons proved no match for God Neptune, until Scuba and Diver took control of the Seacons' ship. God Neptune, infuriated, pursued them into the sea. When God Neptune caught up, the two rigged the ship to explode and jumped overboard. The ship exploded, sending God Neptune airborne and making him disassemble.
The Seacons were later seen on the ocean floor in pain, with Halfshell vowing to get revenge on the Cybertrons.
