Undercom C.Sans

Backstory
C.Sans stands for "Classic Sans" meaning that he is not the only Sans exist in this AU.

It all started with Error Sans freezing the timelines as Classic Frisk was finishing his first Pacifist route. Error Sans froze the timelines to prevent the destruction of AUs from being undone by resets and true resets. But as Classic Frisk was finishing his Pacifist run, a true reset was unable to take place because the timeline was frozen, therefore the story was able to progress and everyone was able to start their own lives on the surface.

The only problem was when they all reached the surface, the found it to be locked in the Advent-Xcom war. The monsters, having no want to be dragged into it, went off to find a quiet place to build up "Brand New Home". However, the Monsters built their settlement between the Advent Training Blacksite and the Xcom Mexico HQ.

Soon after finding his brother and the settlement, Sans meet Jax Sunstrider, an Advent Shieldbearer. Jax offered that Sans and his brother join Advent, in exchange for allowing the settlement to live in peace. But, low and behold, Xcom found the settlement and attacked it, thinking it was an Advent outpost, thereby dragging the monsters into the war.

Sans now serves as the Advent ambassador for the Monsters, fighting to keep his friends safe as well as defeating the Xcom terrorists.

Appearance

His right eye flashes blue and orange when he uses his magic.

Personality
Undercom Classic Sans is just like his original Undertale venison. Lazy, caring, pun making, and ready to dunk anyone who messes with his friends.
