History: Starscream attacked the Autobots on Cybertron and beat up Landmine. Vector Prime, in an attempt to save him, sent him through a dimensional portal to Earth. He was discovered by Coby, Bud and Lori. He recounted the history of Unicron and the black hole to the kids. Badly damaged, he had to wait and recover before rejoining any missions. He was very eager to help, and rejoined his comrades in time to battle Starscream and protect the kids from a stray blast. After the coordinates for Jungle Planet were discovered, Landmine and Overhaul were ordered to go through the dimensional portal. After Overhaul entered, Landmine was shot by Thundercracker. When the Autobots went to Velocitron, they rescued Hot Shot. Hot Shot then sank into a depression. Landmine, wanting to snap him out of it, said some very harsh things.

Official character text from packaging... 
With a wisdom born of experience, and a tactical knowledge unmatched among the Autobot ranks, Landmine is a soldier other 'bots follow without reservation. He suffered heavy injuries in the final fight with Unicron. After crash-landing on Earth, he was repaired by the new human allies of the Autobots. An excellent battlefield commander, he's determined to prevent the Decepticons from gaining an edge by recovering the Earth Cyber Planet Key.

Cyber Key Code: dr94
Landmine is one of the oldest members of the Autobot team. But that doesn't mean this guy can't hold his own when it's time to rumble... In fact - he was the Autobot who first taught Optimus Prime how to fight!!

Abilities: Possesses great tactical knowledge and gritty determination.

Weaknesses: Landmine doesn't know when he's overmatched.  Without hesitation he'll charge straight into a fight with 'bots obviously more powerful than he, without support.
