not to treat some bullshit I made up like it's canon and has any gravitas at all (but that's exactly what I'm gonna do)
I'm getting Exarchon (and Peratrix...) vibes
for a lil context, this was an unrelated song from an ongoing-story song producer, who remastered it and made it connected to major villain responsible for everything bad in a domino way (and then occasionally making it worse on purpose), the song now implying before all that, he may have had a failed relationship. this is not his motive for villainy, it's just an unexpected facet the character never had before
omg kagamine len I know that guy
honestly I would've loved to get more Exarchon backstory in-canon, I mean we know he was probably kidnapped by Quintessons or something like that but other than that he's just the big bad who comes in and ruins everyone's day three times over. It's one of my biggest annoyances with IDW: not enough god damn lore!!!!
You know what, the continuity's been dead and buried since 2021, I can take this as canon, why the hell not. Man the consequences to losing lovers really is a spectrum, sometimes they make you hallucinate ghosts and sometimes you just destroy an entire planet's way of life (or a few, counting Neutronia). We have got to get these dramatic-ass robots better therapists mannnnn
Wait omg crazy idea based directly off the song, maybe it's the vibe you were going for, but: Exarchon got rejected by Peratrix > in his desolation he left Cybertron and tried to get as far away from the memories/emotions as he could > he went so far he got abducted and turned against his people > came back to Cybertron with the intent to destroy it, ran into Peratrix again there and purposefully usurped her body so that they could 'be together' (especially since morals would no longer be holding him back, he could just pretend while wearing her as a shell and idkkk) > though wearing her skin probably did nothing for him so she died for literally nothing and he, uh, I dunno if he feels regret or not but whatever it is is enough to stick with him for the rest of time. Yippee woohoo lore!
Side tangent: I just checked his tfwiki page and it says he was 'once a trusted and respected figure in Cybertronian society', so the plot thickens! Also doesn't state why he left Cybertron, so the above mentioned could probably be plausible unless I forgot something!
