Starscream being Megop sparkling in G1, Prime, Animated, Armada, Cyberverse and Earthspark. Megatron is the Carrier BTW (because it's funny) how the Autobots and Decepticons treat him?
When it comes to animated, Starscream is definitely older than Optimus. Megs and Op don’t really have a history before the show’s first episode like the others. So I’m going to leave this one out.
When it comes to Prime, I definitely headcanon that Starscream is older than Optimus and Megatron. So Prime will be left out of this as well.
Starscream is the second in command of the Decepticons, mostly for Megatron to keep an optic on him.
The seeker sees Soundwave as more of a dad figure than Optimus.
Most of the other Decepticons don’t mess with Starscream, out of fear of what Megatron would do them. Skywarp is not one of these mechs and will mess with the tri-colored seeker like a big brother would.
When it comes to the Autobots, a few members of high command know the truth.
Jazz will go into the Decepticon base and make sure Starscream is okay and leaves cubes for him.
Prowl wants to capture Starscream, and “de-brainwash” the seeker from Megatron’s influence.
Ratchet won’t hesitate to patch up Starscream or yell at him for being an idiot.
Starscream is the beloved son of Megatron, and he’s sheltered for most of the war.
Megatron wouldn’t tell Starscream about his sire, or tell Optimus they had a sparkling together.
Optimus finds out about the seeker by accident, during the raid on a Decepticon base. Op being Op, decided to take the sparkling with him to keep him safe.
Starscream is scared by the Autobot, and would be doing his best to go back to his carrier.
Red Alert would run a test on Starscream to find out who is carrier and sire are, and is shocked when it’s Optimus and Megatron.
After that, Starscream kinda goes between the two during different points of the war.
Rebellious teenage era Starscream. Doesn’t like Megatron’s overbearing nature and OP’s distant attitude.
Starts out in Megs care, then once they leave earth is in OP’s care.
Thundercracker and Skyfire are the nicest to Starscream.
Does not side with the quintessons, but at the end he doesn’t want to stay on Cybertron. Starscream wants to forge his own path in life and explore the stars.
By the time the series starts, Starscream is an adult. He sees both of his parents as flawed.
Megatron betrayed the cause and the mechs who trusted him, Optimus sold them out to Mech.
Starscream wants to continue the cause, to prove they can still have the good life Megatron promised in the beginning.
Megatron is conflicted when Starscream is locked up, but Optimus assures him that it’s for the best. Starscream can’t get hurt if he’s safe in the mech prison.
When Starscream escapes, Megs is worried. He doesn’t want his sparkling out with Mandroid on the loose. Optimus doesn’t want Starscream to hurt any humans.
