Ash Crystillia Evil Granger was named by Neil C. Granger, Ash's brother. Ash was invented when Gaster asked Neil to test his first cloning machine. The result was Ash Evil, a being with Neil's incredible power, and all the hate in the world. Although at times he helps his brother when something is threatening both of them, Ash will fight Neil for the most part. Their relationship is like one of Error!Sans and Ink!Sans.
In this AU, Ash magically appeared one day when Neil came back with him from Hotland. This most likely means that Gaster also cloned Neil in this AU, although the results were much better, with Ash being a better person. In this AU, Ash Evil's name is now Ash Hip-hop.
Ash Evil's personality is a lot like the one in regular Undertale, but instead of him being nice sometimes, he is PURE EVIL.
Ash is similar to his brother, but instead wears a black hoodie, dark blue pants, black shoes, and has black hair and eyes.
Ash wears his hoodie over his head in this AU.
Ash wears a black robe, a black wizard hat, and has a staff with an orange glowing sphere on it.
When you fight Disbelief Ash, he has his normal clothes on, except that he wears his brother's red hoodie.
Ash has a number of different attacks he uses against the player, which are powerful, but not as powerful as his brother. In a sense, Ash is like the Papyrus version of the two brothers, while Neil is the Sans, who avenges his brother in the genocide ending with powerful moves.
The fight takes place in Snowdin, right after you spare/kill Papyrus. Ash will block the way, and fight you. IF you spare him, he will go tell his brother how nice you were. If you kill him, Neil will not show up again until after the Sans fight.
Ash wields a sword that is seemingly made out of smoke, since he uses Fire and Shadow magic. He will use his brother's moves, along with his own moves, making his attacks almost as difficult as Ultra Neil, but not quite as tough.
When he is defeated, he will talk to himself, saying that he failed to avenge his brother. Shortly after, he will turn to dust.
Ultra Ash is the final boss of the pacifist route in Universetale, and the final boss of a neutral route (ONLY IF THE PLAYER KILLED ASH). In Universetale, Ash will initiate the fight, but Asriel disintegrates him before he can do anything. It is rumored that he is the most powerful enemy in Universetale, but it is not known to be true. In regular Undertale, Ash will fight Frisk after they defeat Omega Flowey, but only if the player killed Ash in Sowdin. Frisk cannot die in this fight, for every time they get hit by Ash, he dies a little more as well. Once he reaches low HP, he will plead mercy to you. If you spare him, he will thank you and disappear. If you kill him, it will teleport you to the Judgement hall, where you fight Neil as if it was a genocide run.
