Curate, connect, and discover
Concepts I would like to explore from Killer's original story:
The Metanarrative of the Player's choices and desires (i.e., our choices and desires, independent of “Chara”) shaping the universe that Killer inhabits, most directly on Killer himself, especially as the choices and desire of the Player are so core to the narrative of Undertale itself
Killer turning against Nightmare and working to try and “fix everything” while carrying the weight of the lives he’s taken, symbolized in him keeping the name “Killer”
Killer/Sans resisting the Player’s reprogramming, defeating Chara, and never joining Nightmare in the first place (which I imagine he’d do largely through the support of his brother & friends)
The clash of Sans's core character flaw/struggle being his resignation & nihilism, vs. the artificial Determination he gains, and how that could inform and shape the way I write Killer’s personality
