Underverse Season 2 is the second season of Underverse, created by Jakei95. It takes place immediately after Underverse Season 1. Sans is finally back home, but it couldn't have been at a worse time. With the rest of the multiverse destroyed, XGaster plans an invasion on the main universe with the rest of the XTale cast in search of a perfect world. The first episode will release in 2020.
The unwilling owner of his world, Sans traveled through multiple AUs before he witnessed the destruction of the rest of the multiverse. He has been sent back to his own world, but he's not out of the fight just yet.
Created with the only purpose to compile all the data generated during the Timelines, as well as keep XGaster’s personal notes during and after the X-Event development. XGaster had all his trust on her until he discovered she was part of Chara’s rebellion in the 4th Timeline. Alphys was overwritten into a loyal and emotionless assistant. She is still able to think for herself, but she doesn’t want to get involved in trouble anymore and only focuses on obeying her creator.
He was always destined to grow up alongside his two human brothers and maintain peace between humans and monsters in the world created by XGaster. He never became Flowey. However, he can transform into his Exterminator version (Flowey X) with the Overwrite button. Asriel is XGaster’s favorite “weapon”.
XGaster never liked this creation, who always maintained the qualities of a kind man despite his miserable and lonely life, like in the other Universes. Now he’s only a being full of remorse and rage aware of the reality of the Multiverse.
She is aware of all the events that occurred in her Universe, the true fate for her son Asriel and her relationship with Asgore in the Original Universe. In her mind, she only keeps the memory of her loved ones smiling in a peaceful and happy world before everything went out of control. That’s why she refuses to open her eyes, fearful of forgetting that image and facing reality.
Muffet was the first one to encourage Chara to rebel against XGaster. After the events of the 10th timeline, she was overwritten into a killing machine. She can create illusions with her poison and stopping time.
She was the first creation who attacked her own creator. Now she’s his personal bodyguard along with Papyrus. All her happy memories with Alphys are fake. But deep inside her soul, she still has feelings for her. She doesn’t believe in justice anymore.
When the X-Event initiated its training, it decided to use this resource and make him a robot with many qualities, the most outstanding being an unstoppable Royal Guard, an idea that gets XGaster’s attention and giving origin to the final concept for his perfect story. Mettaton has an insatiable appetite and always eats anything in his way. His favorite food is souls, both humans, and monsters'.
His kindness and optimism captivate everyone else, even getting to confuse XGaster. More than a simple creation, XGaster sees him as a closer relative, as he sees in him the innocent and pure side that he lost long ago. Papyrus feels great remorse and disappointment towards Cross after having been exterminated by him in the past.
The main reason there was such a large gap between Season 1 and Season 2 was because Jakei wanted to take a break from animating long episodes. She decided to work on the XTale miniseries, which ended up becoming a lot longer than she anticipated, leading to the two-year-long break
