(My AU, the predacons killed Star'Scream, and some other ppl that work with mech came and experimented on him. Though they changed everything about him, but it resulted him having memory loss. So he doesn't remember the good parts in his past, and SOME bad parts as well. He only remembers the worse parts, such as Megatron and the predacons. So he doesn't remember Megatron's toxicity towards him, or how possessive he was with him. He also doesn't remember his romance with Optimus either.)
Megatron; "Whatever, as long I can be with Star'Scream."
Star'Scream; "What are you. . .oh, I see. I don't know, I just thought my old look look too much. . .erm, cowardly."
Star'Scream; "And I'm not adorable! Never call me adorable ever again!" -Growls-
Me; "I swear I wanna throw Megatron into a volcano, just to show how much I hate him."
