Aliza is the protagonist of Horrortale, and the ninth human child who fell in the underground.
Aliza only wears a violet dress, she doesn't even wear shoes nor weapons. But she used to wear a green ribbon. Her hair is light brown and reaching to her shoulders. She is also lot more expressive than the original protagonist, but most of the time she has closen eyes.
Majority of her story can be found on Flowey page. Please look in there or write it here for yourself.
After Aliza escaped the ruins, she met Sans, who pranked her by pushing a spike in her hand. He told her that Papyrus wants to catch her. Sans then told her to hide behind a corpse. Afterwards, he told Papyrus where she is hiding. Papyrus found her, but let her go because he thought that she is too easy to catch, and that she is only pretending to be weak.
On the first puzzle (Orb and beartrap) Aliza got her head chopped of by a beartrap. On the second try, she used the orb to analyze where is the beartrap.
Then Aliza saved snowman and he gave her his nose.
On the second puzzle, Aliza got stuck in the snow and die. On the second try, she realized that she can't solve it, so she used her first Freebie.
Toriel-Like in the original story, Toriel is really caring. She really cares for Aliza too. Aliza likes her, but sometimes Toriel really scares her. Toriel tried her best to keep Aliza from escaping, but then she understood than Aliza really wants to go. Aliza had to promise her, that she will help monsters escape from the underground.
Flowey-He is something like Aliza's tutor. He seems to really care for her, for some reason.
Sans-Aliza seems really scared of him. Sans will scare her,ignore her and make her suffer but he will never eat her.
Papyrus-He tried his best to test Aliza with his puzzles. When she survived, he let her go. He seems to like her.
