Arcee = Red Alert? Arcee was a intelegence officer, and though we know little about Red Alert, she appears to serve a similar function. Plus, Arcee had no memory and may have taken on this new personality.
Arcee turning into Red Alert doesn't sound right. If Arcee does undergo some kind of personality change after her memory wipe, I hope she becomes like the badass comics-verse G1 Arcee.
No chance. They already mentioned that Arcee only gets a slightly more detailed character design, because she actually has a vehicle mode, now.
Well, there's also G1 Red Alert, who was like, I don't know, in charge of Security or something like that, or on occasion a malfunctioning nut case, but I don't think he ever served the function of intelligence.
