I wished that I were dead, I don't wish I were dead. But somebody's got to go.
(this take is still an early wip! i will also rework this page to be nicer eventually ^_^)
Sans
The skeleton. Out of options.
Nothing else worked, evidently. Now, he's forced to his last resort - getting stronger. Wears a visor to hide his face so he doesn't have to see who he kills.
The primary goal isn't just to kill the human. It's to get strong enough to put them into a battle so grueling and unfun that they give up.
Hanging on to his own sanity by a thread. Becomes completely despondent by the end.
Flowey
The flower. The only one to fully remember.
Initially was furious about how boring things had become, eventually allied himself with the human after realizing how different things could be this time.
Tosses healing at the human during combat, can help whittle away enemy health if the human gains enough TP to use his magic... and maybe steal some kills for himself.
