What Underswap!Sans didn't understand was that he was also harming Underswap!Chara in the process. X-Event!Chara pauses it for a moment, thinking he's talking to Cross, but isn't, and they head back with their battle. His belief to believe in someone is broken, and he completely goes all at war with X-Event!Chara. He's transformed into an amalgamate, and is used to battle it out with Ink before he's reverted back to himself.

He tries to tell everyone to actually help Cross!Chara up, but only after they absorb almost all of Underswap!Chara did he started to question him. After Ink apologizes to Cross regarding his world's status, Underswap!Sans suggested that he needs a home, and welcome him, which Cross does by almost killing him, which was stopped by Underfell!Sans and Sans. Underswap!Chara heads over to where Underswap!Papyrus and Cross are, and by looking through Underswap!Sans does Cross gets familiar with his coding. He suggested that he went into the city, and as they all traverse there, he finds the queen, having been cut by Cross himself. However, they slip over Underswap!Sans's cape, spilling the paint, and that's where Ink!Sans goes through with Underfell!Sans and Classic!Sans.Ĭonfused at first, he recognizes Ink, and he explains that Cross might've went into his universe. First seen in the cliff-side looking over the city, Underswap!Sans and Underswap!Chara both unpack their belongings from the Underground, and he explains to Chara regarding those paint canisters.
