Legion!Sans

Legion!Sans, also called Lee, is the main character from the story 13 Nights, and joins Nightmare's Brood as a replacement for Murder!Sans. In JumpVerse, the original Murder!Sans is already dead, and has been replaced 12 times before Lee takes the position, making him the 13th person to fulfill that role. However, he isn't the first of the Murder!Sanses to refer to himself as "Legion."

With only a few minor variations, Lee's original AU was very close to the Classical Timeline. However, Nightmare discovered it and took control to manufacturer events akin to Dusttale, attempting to turn Lee (who still went by the name Sans) into a Murder!Sans. However, Lee never subjected himself to killing anyone to gain LV. Instead, since only his mind would chance with each reset, Lee focused on perfecting various skills, including physical combat with improvised weapons. Lee refuses to use knifes or firearms.

After nearly two years of Resets, Nightmare is finally came in need to have Lee in his Brood. Invading the AU while possessing the Human, he began slowly forcing the memories of the previous Murder/Legions into Lee's mind. This magically induced trauma caused Lee to become a system, with the alter of Murder!Sans eventually committing genocide on his people.

Lee is forced to serve Nightmare for approximately 3-4 years before the events of The Bridge Jumpers starts.

Canon notes:

Legion's original AU takes place under a mountain in modern South Korea.

He is bilingual in Korean and English.

He's an excellent cook and piano player.

Legion is a system. His alters are:

Lee - host (Empathetic and generally very mellow. He cares deeply for the well being of others.)

Sport - Swap!Sans (playful and optimistic, though very shy around new people. Always confused as to why he craves a cigarette, since hes the only one who doesn't smoke.)

Thomas - Swap!Papyrus (serious and a little rough housing, but doesn't have murderous intent.)

??? - Murder!Sans (he refuses to choose a name, instead referring to himself as the system name, Legion. Though he will answer to Murder and Dust, it typically annoys him. He holds the bulk of the system's worse memories and is the one who carries out the most vile of Nightmare's demands.)

Instead of a physicist, Legion is a psychologist.

Legion is mentally 30 before he is pulled from his AU, though physically 28. Nightmare forcing the memories onto him adds an additional 20 years (not accounting for the normal years of previous character memories), but his alters do not share equal scopes in time- Murder having experienced the most amount of time than the others.

Legion!Sans is canonically shipped with Diva!Sans.

There is also a 14th and 15th Legion that comes after Lee before the Murder!Sans role is no longer filled.
