Curate, connect, and discover
Kind of plays with the 4th wall breaker Starscream but in a completely different direction.
As in due to his immortal spark being like a constant in every universe you have this one flux where they all are in eachothers bodies for a split second.
They've seen the other dimensions, they understood what it was and then bam it was gone just like that. They can't recall what they witnessed or what secrets they came across.
Except for one of the Starscreams who now is aware of the other dimensions and also the writers and us the audience.
He can't see us or talk to us though. But he's become less energetic to everything until he cracks under the pressure of knowing his pain is simply for amusement and starts to find a way to reach us/writers to extract his revenge.
And he has a sword (very important, this is).
Also he has this glitchy power I don't know exactly what it would do but I feel like he'd be able to glitch his body to other dimensions whilst still being active in his so he can't be hit most of the time (there will be a massive drawback obviously, can't make it that easy).
