In Undertale, Alphys is the scientist who helps Frisk find her way through the Underground. She’s a dinosaur-like monster who loves anime (and Undyne) and she’s very shy and doesn’t have much confidence in herself. She usually wears glasses and a lab coat, but if you wish to cosplay her dating outfit, she wears a black dress with white polka-dots.March 19, 2016 by Ladona Rosa
In Undertale, Chara, also known as the First Human or the Fallen Human, is the first human to ever fall past the Barrier on Mount Ebott into the Underground. This person is who the player names at the start of the game, and not the controllable character who is played throughout the entirety of Undertale. Chara is seen to be wearing a lime and cream colored striped shirt, brown pants and shoes. Compared to Frisk, Chara is of a lighter skin, hair color and has red eyes.
