As a part of being Sentinel Prime's precious and pretty human pet, he'd sometimes have you perched on his shoulder in one of your prettiest outfits throughout the day as he goes about doing his job as a Prime --(and as a traitor to Cybertron).--
Sentinel, tall Cybertronian. His body is primarily royal blue, with gold acting as a secondary color, along with numerous silver highlights, and an unknown symbol. On his forehead, painted yellowish-gold, His eyes are a bright blue color, and he also has a golden set of wings on his back.
If he ever shows up in a public place and bots are crowding around him and fawning over him like he's some kind of hero or god, maybe a reporter will ask about the weird organic matter on his shoulder. that he found on the surface and why he decided to take you in. He will come up with the most saccharine sad story to make himself look like a saint.
(Which is actually not true, this bastard just stole you with the ground).
If fashion was in fashion in Iacon City, Sentinel Prime would put you on every cover because you're too cute not to advertise. You'll be popular with the people of Iacon.
He knows that many bots are interested but Over time, he realizes that he feels something more for you, he will never admit it because of his hypocrisy and big ego.
One day he finally returned to his personal cabin which was almost the highest building. He was a little tired of all this meeting and important matters as the ruler of Cybertron.
"Oh, my dear pet.." he sighed as soon as the door closed behind him. he walked towards you.
