Ultra Frisk

UNDERTALE AU Series: Frisk's too much determination LORE: For this universe, Frisk spared too many monsters in the Underground and once he finished sparing every monster, he was meant to see Asgore. Until then... Asgore helped Flowey trap him, and used the determination pill so Frisk can eat. After he transformed into some buffy big muscular child, he started to attack others in the entire underground. Sans and Papyrus are the main characters in this universe by the way. Frisk is as well, but still mindless and can speak as well, but can't recognize his friends or anyone. Asgore knew it was risky, but he has one responsibility to take it. Now... It's time for Ultra Frisk to rise and smash. (Also, Sans will be beating Asgore up once he found out, and Papyrus will try to stop him which will be impossible.) Enjoy! Characters: Frisk, Sans, Papyrus, Undyne, Alphys, Toriel, Asgore, Flowey, Muffet, Mettaton, every monsters I don't know, Chara, etc (Also, I have to use Frisk different voice because it doesn't have child voice. Oh, and Frisk wears a skeleton pajamas. Meaning it's no shirt, or pants, just the skeleton outfit that does not rip.)
