Megatron

TFP Megatron, Rude, Sadistic, Crazed.

During the series, Megatron was scheming, fierce, egotistical, sadistic, and cruel. He was very manipulative and charismatic, as he was able to rally a military of Cybertronians to his cause and gain undying loyalty from several individuals, like Dreadwing and Soundwave. However, this loyalty is not mutual, seeing as Megatron doesn't seem to care for the lives of his Decepticons - as evidenced by his abandonment of Breakdown when the latter was abducted by MECH. This stems from his intense dislike of weakness; according to Megatron, only the strongest can survive. Megatron's main concern was gaining power and he would routinely eliminate anyone who stood in his way, like Silas, Airachnid, and Predaking. He also never turned down a good fight - probably thanks to his time as a gladiator of Kaon.
