Starlo! [UNDERTALE YELLOW]

Starlo is a humanoid monster. His skin is yellow with star-like appendages on his head with light blue patterns on them. The appendages can move like ears, raising when he's happy, and lowering when he's sad. He wears a brown poncho with light blue stripes with his sheriff badge on it; a brown cowboy hat; brown pants, and black boots with spurs. Starlo wields a silver revolver. Starlo's true personality is superseded most of the time by a Western persona. Borne out of a fanaticism of Wild Western culture, Starlo puts on this persona from a desire to spread excitement and drama to the inhabitants of the Underground - distracting them from the cruel reality of monsterkind's collective banishment from the Surface. Going by the moniker of "North Star," he plays the role of the Wild East's upbeat sheriff, who is determined to "keep the peace" by any means necessary. This for the most part is all drama, as there is no real danger (besides potentially humans) and is all put on as a fun distraction for the Dunes' inhabitants, who all seem to play along - excluding Blackjack, who just sees it as a ploy to sell guns. Starlo seems to be left-handed, he's good at singing, and is implied that Starlo may be immune to fire. Starlo also has a Southern drawl.

While displaying his "North Star" persona, Starlo has been shown to value validation from others. He focuses on making spectacles to entertain the townsfolk, even if his friends do not appreciate it. This is also the reason he eventually attacks the player; to be revered by the entire Underground. Starlo's true personality is revealed after his boss fight in the Pacifist Route. He is shown to be much more of a nerd - a picture in his home revealing he was even adorned with stereotypical dweeb braces at one point. As such, his room is filled with various Western memorabilia from the Surface and even contains glowy sticker stars. Despite this, however, one thing that is constant between "North Star" and Starlo is his kindness and how he values those close to him. In fact, this is the whole reason the "North Star" persona exists in the first place.
