Type of villain
Power-hungry egoist

Sentinel portrays himself as a friendly leader of Cybertron, ready to help whenever needed. He appears as a trustworthy and wise ruler who loves his Cybertronian people and is always ready to support his subjects. His image also combines a playful, fun-loving personality. He often delivers long, mock-epic speeches, assuring the inhabitants of the metal planet that he is diligently searching for the Matrix of Leadership to save Cybertron.

But in reality, he is a cruel, power-hungry egotist who will do anything and kill anyone for his own sake. He is a petty, despotic, and totalitarian dictator whose goal is simply to live in luxury and glory. He takes great pleasure in being praised by Cybertronians, and has essentially created a divine image of a mission that will save Cybertron and find the Matrix of Leadership for the Energon supply. In reality, however, he was simply creating a cult of personality around himself to feed his ego and control the minds of his devoted people.
Sentinel is extremely arrogant and smug. Even his "heroic" speeches are tinged with arrogance, and when the mask of friendliness falls, he immediately reverts to his lofty nature, revealing all his narcissism and god complex. When D-16 accuses Sentinel of betrayal and the murder of Megatronus, instead of resisting, Sentinel simply declares himself to be a good person.

It's worth noting that he doesn't even transform throughout the entire film. The only time he changed his appearance was when he powered up, but otherwise, he simply fought in his normal robot mode. This shows that even stealing Megatronus's T-code was futile, and that his long reign had made him extremely lazy, as he never faced true enemies, only those far weaker than himself. Even D-16, who rarely fought in real life, could creatively defeat Sentinel after acquiring his T-code.

After his near-death experience, he developed thanatophobia, specific phobia, agoraphobia, physical disorders (tremors, stiffness), dysthymia (dysthymic disorder) and dependence syndrome

Appearance before
Sentinel is a robot with blue, yellow, and white skin. He has wings on his back that extend during flight. His legs act like rockets, allowing him to fly. He transforms into a jet. His arms can also transform into a blaster when needed.

In combat mode, his body takes on the appearance of armor, and a mask appears on his face. Purple glowing elements also appear in this mode, a result of Megatronus' use of the T-Cog.
He's 40 feet long (or 12 meters). That's because he's Cybertronian.

Appearance after
Without his T-Cog, Sentinel stood 9.50 meters tall. The only gold details remaining were on his helmet (inside the crest), at the junction of his neck and shoulders, and on his hip plates. Dark gray details and dirty white became predominant (the dirty white remained only in some areas of the body). His wings remained, but they were scratched, chipped, and a piece had been broken off from one. Shockwave successfully removed the jet engines from his legs (without them, the wings are useless) and discreetly embedded a GPS tracker and beacon into his body, which did not interfere with Sentinel's movements.
