Maximals, No More is the thirty-first episode of the Beast Wars TV series.
Within the Maximal base, Dinobot compares Predacon installation locations with the symbols on the Golden Disk, and observes that Megatron's "plan proceeds, even without the disk". He ponders his fate should Megatron succeed, and wonders if he is willing to betray his Predacon heritage. Optimus Primal contacts him for a survey mission, and Dinobot puts his research aside for the moment.
Later, he rides vehicle mode Rattrap into Predacon territory, musing as he does that "there is always battle here". Rattrap ain't buyin' it, until Inferno bursts out of the ground and attacks. Inferno and Dinobot square off, while Rattrap gets the drop on Quickstrike. Silverbolt moves to assist Dinobot, but Waspinator shoots him down, causing him to crash into Dinobot, deactivating them both.
Inferno carries Dinobot off to the Predacon base, but Rattrap takes out Waspinator before he can carry Silverbolt away.
At the Predacon base, Megatron is eager to chat with his former comrade-in-arms. Dinobot breaks free and reaches Megatron, sword in hand, but the guns of the other Predacons prevent him from doing any damage. Before the fight can continue, however, Dinobot offers to change sides. Unconvinced, the Predacons finally settle on a "Predacon challenge" to test Dinobot's loyalty. Quickstrike is selected as an opponent, an invitation he readily accepts.
Rattrap goes hunting for Dinobot, sending Silverbolt back to call in Optimus.
After a brutal fight, Dinobot triumphs over Quickstrike. Megatron orders Dinobot to finish him, but Dinobot refuses, saying Quickstrike is an able fighter. Megatron accepts this, then demands that Dinobot return the golden disks. The alien disk is in Rhinox's hands, but the other is hidden from both sides. Megatron orders it returned immediately.
Rattrap observes Megatron and Dinobot flying past, and follows. At the mountaintop grotto, Dinobot uncovers the Golden Disk, and, with some trepidation, returns it to Megatron, wondering as he does if he's dooming his race. Megatron is about to run him through when Rattrap arrives, blasting Megatron aside—but Dinobot in turn blasts Rattrap.
Megatron orders Dinobot to finish off Rattrap as a final test of loyalty. After a long moment of hesitation... Dinobot turns his sword on Megatron instead, telling him that his ambitions are insane and will destroy Maximal and Predacon alike. With Optimus and Silverbolt incoming, Megatron retreats.
Dinobot confesses his betrayal to Optimus Primal. Having foolishly believed he wanted to share in Megatron's imminent victory, he now wishes to fight with the Maximals till they win or are destroyed. Optimus accepts this, but leaves the final call up to Rattrap, who finally relents after some obligatory insults.
Dinobot tells Primal he has a matter of great importance to discuss... back at base. Dinobot's final punishment is having to hitch a ride on Rattrap back to base.
