"Let the experiment do as it pleases, follow its game... Be the hero or the villain of its own calamity until I decide when to start Phase Three."

**Underverse Season 1** is the first season of *Underverse*, created by Jakei95. Trouble begins to brew when half of Sans's soul is stolen by a thief from an alternate universe. Once Sans begins suffering side-effects with only half a soul, he, Ink!Sans, and a whole group of Sanses have to stop him and the spirit inside of him, to discover out the true meaning of the X-Event.

## Synopsis

Sans wakes up in a strange universe to meet Cross!Chara, who demands that he should keep him in his universe. He refuses, and Cross!Chara takes half of Sans's soul and runs off once Ink!Sans arrive to stop him. They absorb the soul, and make a deal with Nightmare!Sans to cause suffering whenever they go to other universes. Ink recounts to Sans that he met Cross in a new AU, and discovered he was the sole survivor of a Genocide Route without reset possibilities. The two became friends, but tensions rose when Ink told Cross that he couldn't bring back his world. Soon after, Error!Sans took Cross's soul, and though Ink protected Cross from Error's attack, Cross ran away in order to take Sans's soul.

Sans decides to stay rather than fight. However, after he has difficulties in a volleyball game, he chooses to join Ink, and tells his Frisk to keep watch for him. The two arrive in Underfell as Cross marks areas to take back to Xtale. Underfell!Sans attempts to mock and resist his efforts, but is soon defeated. Ink and Sans both arrive, and the two battle against Cross and Underfell!Sans, who has fallen under Cross's control. After Sans distracts Cross, Underfell!Sans is freed from his control. Cross!Chara forces Cross to escape being killed by Underfell!Sans, and the two flee with Snowdin's code.

Sans is given a tip to defeat Cross by Core!Frisk, and Underfell!Sans joins up with him to avoid severe punishment from his brother. After Ink talks with Error regarding recent events, Dream!Sans spies on XTale to figure out the next AU Cross plans to target. Cross!Chara isn't happy that they haven't gotten a human soul and attempts to take over Cross's body, but he is narrowly stopped. Cross heads to Underswap next, and discovers that this universe's coding reminds him of his own. Conflicted, he continues to work for Nightmare, but thanks to Core!Frisk's advice, he is swiftly beaten and Sans gets his soul back. However, Cross!Chara absorbs the soul of Underswap!Chara and teleports Sans and Underfell!Sans out of Underswap to torment Underswap!Sans, Underswap!Papyrus, Underswap!Chara, and Ink.

As the three of them suffer from X-Event!Chara's constant overwriting, he demands the strange vial Ink has been protecting. When X-Event!Chara is refused, he uses the Underswap cast as pawns to attack Ink. However, they inexplicably break free of Overwrite. Underswap!Sans and X-Event!Chara battle each other, but when Underswap!Sans threatens X-Event!Chara with a Gaster Blaster, he is overwritten and forced to attack. Underswap!Papyrus gives up because of his inability to stop them. He recounts his good memories, which allows Dream!Sans to return Sans and Underfell!Sans to the fight. X-Event!Chara confides with Sans that his timeline is "not exactly as it should be", and attempts to convince him to rebel against Ink. However, he is stopped by Nightmare, who mortally wounds Underswap!Chara and retreats with X-Event!Chara. Underswap!Papyrus decides to stay in his destabilizing timeline while the others escape to Outertale.

Meanwhile, during Error's dream, he comes to suspicion of Ink's actions and learns more of the X-Event. Once he enters XTale to see the code that Cross and X-Event!Chara have gathered, he blames Ink and calls their truce over.
