You know, TFO from Starscream's POV is VERY funny to think about.
Like, D-16 is 100% a shit ton younger than Starscream- given that context clues seem to imply that D-16 and Orion were NOT online when the Primes died 50 cycles ago, but Starscream, as the leader of the High Guard not only was, but had been for some time at that point to get to that position.
Which means that from HIS POV this young upstart bot just rolled in, beat his ass, ruined his voice, usurped his role as leader and stole his guys.
Like. Yeah no wonder he's gonna end up constantly trying to overthrow Megatron lol Man stole his fuckin job and he's probably salty about it.
