Saw ur guest1x art and omg pls lemme hear u out I haven't;t even thought Abt them til now-
I'M ACTUALLY SO GLAD YOU ASKED... BTW SORRY FOR THE LATE REPLY I'VE HAD THIS DRAFTED
This reply will be dedicated to how their dynamic looks in my head, so it might be a wee bit long
Forsaken—Guest 666 x 1x1x1x1
First, I want to explore their separate characters. This will all be my interpretation because Forsaken lacks backgrounds for each character (or has very little information on them at the time I'm writing this).
1x physically manifested from Shedletsky (as in straight up crawling out of Shed's body in a gruesome way) , specifically during days of Telamon. The way I see it, 1x holds all the memories Telamon had, days where Shedletsky held lots of resentment and lacked genuine happiness. When they separated, Shedletsky gradually began forgetting he ever was Telamon (as 1x took all the memories when he formed), but kept important memories such as having a wife, working for builderman, etc. Meanwhile, 1x was left in the dust, Shedletsky having forgotten and being unaware of 1x's existence for a time—yet when they formally met it felt familiar, but couldn't wrap his finger around it. 1x hates how much "Telamon" changed (in my head, 1x refers to Shedletsky as Telamon), missing an identity that's no longer there and only lives within him. Despite having all the memories of Telamon, 1x does not consider himself to be Telamon, as Shedletsky is the vessel that once made Telamon—making him believe that together they both could pick up what Telamon left behind. However, Shedletsky is happy in the identity of Shedletsky, all that resentment that held him back long ago no longer haunts him. He's happy because he doesn't remember.
For 666, things are much shorter as I don't have much to work with, but essentially she's extremely envious, angry, yet empty. She feels abandoned, and due to certain bad influences (the specter), she craves revenge—take what's lost. Ever since the ban, she's grown bad codependency issues, desperately trying to find something to lean on and something to adore (something to fill in the space Noob left behind when they "abandoned" her).
Second, the actual dynamic with their backgrounds now put into perspective.
666 finds lots of similarities, relating to 1x in a personal level. Both of them are doomed in their loneliness, nurturing either of their yearns while also enabling the other (such as 1x enabling her anger and envy towards noob, and 666 enabling his hatred towards Shedletsky and anyone associated with him). Their relationship is very unusual, and it's impossible for it to be exactly "healthy" with two flawed characters (as with most forsaken ships tbf). But don't get me wrong, they still very much love each other, being affectionate with one another and whatnot.
Let's not forget that they are still partners in crime ! Both would LITERALLY kill for the other
Uhghhh I love them so much, I love them for their flaws
