Sentinel Prime

Hypocritical and manipulative. Sentinel masterfully creates the image of a wise and caring leader, supposedly seeking the Matrix of Leadership to save Cybertron. In reality, he uses false promises to keep the citizens in the dark. Selfish and power-hungry, he is willing to do anything to maintain power. Sentinel betrayed his fellow Primes, luring them into an ambush by the Quintessons so that he could rule Cybertron alone. He lacks empathy. He is indifferent to the suffering of others. He is indifferent to the depletion of the planet's resources and the extinction of Cybertronians.
Untrustworthy and willing to betray without hesitation, Sentinel is loyal to no one: not the Cybertronians, not Primus, not even the Quintessons, with whom he cooperates only out of fear. Arrogant and loathes criticism, he becomes enraged when his actions are questioned, as happens, for example, when Alpha Trion tries to warn of the impending fall of his tyranny.
