This was done on purpose after said actor was cast for the role. Corrupted Character Copy: Several of his design elements (he's energetic, mostly blue, with a very prominent chin) are based on The Tick, with whom he shares a voice actor.Composite Character: Although his name is different, Sentinel's color scheme and his having been friends with Optimus and Elita are drawn from Dion, a friend of Optimus pre-war in The Transformers episode 'War Dawn' who was killed by Megatron.He ends up being proven wrong, much to his chagrin. Most of it comes from being a pompous ass, along with him seeing Optimus as little more than a maintenance bot.

Cassandra Truth: 99% of the time, he's the one who ends up invoking this trope whenever Optimus Prime tries to tell the truth (such as the Allspark being shattered, Decepticons being active on Earth, and Longarm being a Decepticon spy).Canon Immigrant: This iteration of the character was retroactively declared to be a previously unnamed bot in Transformers: Armada (whom, fittingly enough, was also a blue and orange Jerkass) named Sentinel Minor, while a similar approach was taken to include Sentinel in the Wings Universe comics.Usually, it's related to Earth's weather/inhabitants/road structure, but he's also had his body stolen by a human, been humiliated in front of his comrades, screamed like a little girl when encountering organics, failed at driving in the rain, and been wrong in pretty much every arrogant assertion he's made. Butt-Monkey: If you get annoyed at him, just wait five minutes and something nasty will happen to him.Ultimately, this does nothing to reduce his arrogance, it does however, slightly repair his relationship with Optimus, as he finally stops blaming Optimus for Elita-1's fate, and even helps him on Cybertron (even if he does give him some digs about Toxitron looking like him). Break the Haughty: He goes through several Humiliation Congas, including having his head cut off and body taken, losing prisoners on his watch and having his ship taken over (then beaten flung and frozen), getting a beating from his friends, accidentally, when a Starscream clone uses him as a shield.What happened to Elita-1 broke him, which was of course his own fault for dragging Elita-1 into the planet filled with giant spiders but he blamed Optimus for the rushed evacuation.

Break the Cutie: The flashbacks to 'Along Came a Spider' show he was a nice (if somewhat smug) guy who considered Optimus his friend.It seems like he's not a bad fighter, but he's also a lot worse than anyone he fights. Boisterous Weakling: He's very confident in his combat skills, but his combat record is abysmal.Nominal Hero: If his general characterization doesn't establish him as this, then his actions in 'Five Servos Of Doom' and 'Predacons Rising' certainly do.Anti-Hero: While he's an Autobot, he isn't very nice.If something bad happens to him, he's probably done something to make it hard to feel sympathy. Asshole Victim: Of a similar type to Archer.

Aesop Amnesia: Thanks to his ego, none of the lessons he learns about humility or compassion stick.

Optimus and Sentinel in this incarnation, however, are roughly the same age, went through the academy together, and used to be friends.

Adaptation Relationship Overhaul: Prior incarnations of Sentinel Prime (who was largely a character only from G1's continuity family at the time) were usually Optimus' respected mentor.

Their relationship has been strained since. Years back, the two and Elita-1 were best friends until an incident on a foreign organic planet, during which Elita was separated from them and assumed dead. He is an egotistical, boisterous bot who uses his high position to issue orders and command high respect, especially towards Optimus (despite sharing the same rank). Sentinel Prime is, plain and simple, a jerkass. 'If I need a trash-can emptied or a floor mopped, I'll call on my buddy Optimus Prime.
