Astrotrain

Astrotrain was a Decepticon warrior under Strika's command.

History
Astrotrain was present at a HYDRA training camp on Cybertron when a fleet of Dominion ships appeared and started bombing the camp (if Astrotrain wasn't killed by this, he was one of the Decepticons killed by Mazkertis immediately afterwards). When Strika and Perseus came across Astrotrain's body, she realized that if she could power up Astrotrain's transformation cog, he would transform into a spaceship that they could use to pursue their attackers. They did just that, and got in Astrotrain to follow the trail to Saskana.

When they arrived in orbit of the watery world, they located Mazkertis on the planet by using Astrotrain's sensors to scan for CNA. They soon found Mazkertis's gunship and attacked it using Astrotrain's missiles and lasers, forcing Mazkertis to bail out. However, the wizard reappeared nearby floating in mid-air, and crippled Astrotrain with a barrage of energy blasts. Strika and Perseus bailed out before the ship crashed into the ocean, which is where Astrotrain found his final resting place.
