What is Error's like... Role in this? I get he's a bad guy but is he like into the destroyer role fully or not really? Or did he kill the two because he has a bad relationship with TBS or were they accidents?
Error as a character is SUPER fun in TSDS. He's been doing this for so long that he's grown tired at this point and he's currently on a team by himself so he started to feel like he was losing his battles so you know what he did
he went to the original Undertale timeline and said "yk what if I can't have what I want NOBODY can have what they want and I'm taking you ALL down with me" and managed to delete it
which is the whole reason the multiverse is so unstable and all the AU timelines are slowly collapsing to begin with
because Error's a sore loser
and that's also why he's blind
Ink blinded him (on accident) trying to stop him from deleting UT Classic
we call that karma
yeah Error's a little insane now and he deleted Undertale so now he's kinda just reclining back and watching everything die so now both The Stars AND Nightmare are trying to find ways to salvage shit (while still fighting each other bc they wanna salvage the multiverse for very different reasons) while Error is being smug in his beanbag with his seeing-eye strings all over the antivoid
he's a loser and the entire reason for the plot of TSDS i love him
