RipTide is an Autobot warrior. Stoic, heroic, unflinching unfailing… and very, very boring. Still, you could never hope to meet a better Autobot, he's extremely devoted to his comrades, especially the Mini-Con QuickFire.
He transforms into a Mack Truck, an airship, and a robot. His Mini-Con partner QuickFire combines with him in all 3 modes.
Transformers Legends anthology
RipTide was badly injured by a Decepticon attack. Transported to Earth by QuickFire, RipTide reconfigured himself into a Mack truck before falling into stasis lock, near death. QuickFire was able to control RipTide's body while he attempted to effect the slow repairs needed to resuscitate him.
RipTide finally awakened months later, just as a QuickFire was journeying to Yellowstone National Park to prevent a natural disaster from a fight between the Autobots and the Decepticons. He prevents Megatron from destroying Optimus Prime, but is overwhelmed when the Decepticon responds by cutting QuickFire from his chest.
RipTide leaves the Autobots with QuickFire to haul cargo with their human friend Jake.
...or not. During the Unicron Singularity crisis, RipTide served aboard the Autobot flagship Iron Hope. He was called into action during a Decepticon attack on the ship, and battled a number of Divebomb- and Insecticon-type Terrorcons alongside Smokescreen, Ironhide and the Land Military Mini-Con Team.
