Thundercracker is one of Starscreams loyal seekers. He's second in command of Starscream's air forces on Cybertron. He, unlike his two brothers, is more scientific and yet brutish in mature. Always calculating the possibilities of success during the battle than before. But always ready for a challenge.

He doesn't appear until Season 2 but has another cameo in a prequel coming after Season 1.

I would like to have something similar to War for Cybertron with his voice.
