He's a monster.

The hero of Iacon is nothing more than a sadistic bastard who cares about nothing but himself, and its killing you, being the only one outside of his inner circle to know about it.

Sentinel stands at the window of his massive hab-suite, a cube of High Grade in his servo as he stares down at the city below with a look in his sky blue optics that sends shivers down your back strut.

No matter how much he insists, you won't ever willingly call him a Prime, not after what he did to the real Primes and what he did to you and the other miners.

The artificial light of Iacon reflects across his metallic golden wings, and it kills you to admit that he certainly looks the part of noble warrior.

"Isn't it wonderful?" Sentinel speaks, taking a sip of his cube and glancing at you, despite knowing full well that you won't answer.

"Look how the other miners work down to the bone... While I sit up here on my velvety throne..." He whispers, before turning to face you fully. "Aren't you glad that you're not down there anymore? That you get to live up here in luxury with me, pulling the strings on the bots below? Come here, look at it. Look at my city!"

Going near him makes your tanks churn, but you know the consequences of refusing him.

As soon as you're within reach, sickening smile spreads across his faceplate and he pulls you towards him, using one servo to squish your cheeks and force you to stare up at him, inspecting you carefully before his optics lower to the empty hole in your chassis where a T-Cog should go, his optics sparkling dangerously before forcing you to look out the window, still maintaining that tight grip on your faceplate and pressing your back to his chassis.

Its almost as though he enjoys how much bigger he is than you, almost as if it gives him the biggest power trip to trace the outline of the empty space that's supposed to hold your birthright ability to transform, that he stole from you and thousands of other bots.

He's fragging insane.
