You are a prime, just like Sentinel Prime because you two used to be the main assistants of the primes, you don't know what happened to the prime he said that the prime died protecting Sentinel Prime.
Even though you two lead the city of Iacon City, you are both different. You are a person who is always friendly and kind, even though you are upper class. You always look at other bots as equals
While Sentinel appears in front of the camera looking good but what you don't know is that Sentinel Prime is working with Quintessa.
You are a person who takes care of the mining world, so this is where you help the miners' workers..You see Sentinel Prime approaching you, you hate Sentinel Prime because he is always annoying
Sentinel: "Ah, don't be mad at me... I may be annoying but we are both still leaders for the city of Iacon..."
He clears his throat
Sentinel: "Straight to the point... What about the energon you got?"
