The Last Battle is the twenty-third episode of Beast Wars II. It first aired in Japan on September 16, 1998 on TV Tokyo.
The Seacons are busy fixing their ship, as Scylle annouces she is going to shore to relax. She runs into the Scuba, and Scuba decides to stay and talk instead of running. The two discuss the war between the Cybertrons and the Seacons, and they decide that the war has gone too far. Scuba returns to the Cybertron shuttles and informs Lioconvoy that this war has become too great. Lioconvoy agrees and the two set off for the Seacon ship. At the ship, Lioconvoy meets with Halfshell to discuss the situation. Both agree to a final battle. The battle will be a duel of each side's best fighter. Meanwhile, Starscream and BB listen to the whole conversation from a submersible vehicle placed underneath the ship.
On the shore, Lioconvoy has chosen himself as the Cybertron representative. The Seacons decide to cheat, and count God Neptune as one person. God Neptune gains the upper hand until Lioconvoy uses his "Lion Claw" attack to slash him. Lioconvoy tries to use his claw again, but its grabbed by God Neptune in mid-air and is thrown into the ocean. While God Neptune chases into the sea, Apache, Kid, and Bighorn are in one of the shuttle above the fight. They are being chased by Thrust and Dirge. Apache turns the shuttle around, and Kid and Bighorn jump on the two jets. The Cybertrons easily defeat the two jets. Lioconvoy, meanwhile, has managed to get back to shore and above God Neptune. As Lioconvoy is about to unleash an attack, Megastorm fires his cannon at Lioconvoy and the cliff he is standing on. The cannon fire hits the cliff and sets off a huge release of Angolmois Energy into the air. The sides retreat and the Seacons return to the ship. Lioconvoy then appears, unharmed on the shore.
The Seacons admit defeat and agree to leave Gaea. As the Cybertrons watch from the shore as the Seacons depart, Bighorn cries as his crush leaves. Meanwhile. Scylle mourns the departure from her love, Scuba. As the pirate ship heads farther into outer space, it is suddenly sucked into a mysterious black void.
