Guardshell

Back in the day, the elderly Landmine trained many young Autobots, including his old friend Mudflap and Optimus Prime himself. During the opening stages of the crisis that sprung up around the black hole, Landmine was transported to Earth by Vector Prime to save him from the black hole’s power, where he met and befriended the three human children who became the Autobots’ allies. He transforms into a payloader, and can generate whirlwinds with the bladed wheels unleashed by his Cyber Key Power (Tornado Cutter, Cyber Tempest in the English dub). He also seems to be an homage to the Armada Character Scavenger, in transformation and role (as Optimus’ mentor).
