X-Gaster

Personality:   Appearance His appearance bears an X strap around his coat and shirt, and a belt with an X strap around his pants. During his time with the determination he gained from XTale!Frisk and XTale!Chara, his appearance in Underverse is a semi-melted version of his real self. Thanks to X-Event!Frisk, he has no legs, which doesn't matter as he can still float around to move. Near the end of Timeline X, he begins to melt due to the excess determination in his body. Throughout Season 1 of Underverse, he holds this melted appearance. Once he regains his original soul, he stops melting, though not without changes to his original body. In his Corrupted form, he has a sharper grin, narrower eyes, claw-like hands, and glitches where his legs once were. Personality XGaster is more of a mysterious character, showing his isolation to the main characters except in special times, such as when XTale!Sans attempts to murder XTale!Frisk on stage. He's also a very clever man; knowing that everyone would soon revolt against him, he took his own soul and handed it to Ink for safekeeping. Despite this, he shows much more borderline sociopathic and abusive tendencies towards his children, seeing them more as "experiments" than anything else. He barely cares about anyone's else feelings, and only wants them to fall into his own hands, using them as a puppet to his advantage. The closest thing He has to a Redeeming quality in the modern day is his friendship with Ink, but even then he isn't above manipulating him. The Animated prequels display that he was once a genuinely kind being, simply wanting to make a perfect world for his children. However, as time went on he shed every redeeming quality he once had and he became more and more cruel as he grew more and more desperate for his "perfect world". He even displays several signs of outright sadism, finding the anguish his sons had after he killed Asriel and Asgore "exciting," and then after brainwashing Frisk into a killer, he mocked Chara, saying "Frisk wants to play with you". He is also shown to be extremely obsessed with control and shows several traits of narcissism, ranting about his kids for fighting back, accusing them of being "ungrateful". He also calls the other universes that aren't his own "garbage". This all shows that beneath his stoic, calculating demeanor he is mentally a child, seeing his universe as a toy box. In XTale IX, he seems to briefly show a soft side again after interacting with Papyrus, saying how not having power of the world gave him a new view of it. Before mentioning that he "Hated it" and saying how he had gone too far to stop now, going back to his old self. After his Future vision shows him the events of 0.4 as well as what leads him to it, he becomes Obsessed with ensuring this Will happen. He also shows quite a bit of Determination, as its regularly shown to be tiring and Exhausting yet he continues working toward it. Abilities XGaster is the sole creator of XTale, allowing him to use the Overwrite button at will. However, he loses some control over it after he sent half of his soul to the X-Event. This allows him to Reset, but destroys any chance of using the Overwrite button. His Reset button doesn't even restart the whole timeline again; it brings back everyone to their normal position, but fails to erase any memories that the characters had before. XGaster, as the creator of his works, can also control the inhabitants of XTale if necessary. This can be shown if the inhabitant uses his own eyes instead of their own. If fighting alone, XGaster can use his multiple hands to stab his enemies with. Due to the power of his soul, XGaster has the power of foresight, which gives him the ability to see visions of the future. His foresight is not all-seeing, as he can only see glimpses into the future, which sometimes leads to unexpected events such as Asgore getting poisoned in Birthday Party or Fatal_Error trying to steal his code in Underverse 0.7 Part 2.
