Yellow

Yellow is one of the "7 Colored Flowers" introduced as a prominent character and antagonist in Chapter 5. Originating in the Light World as a yellow flower from Asgore and Toriel's old wedding bouquet, he is granted a tall, gangly humanoid form when a Dark Fountain manifests inside Asgore's flower shop, the Flower King. Strongly mirroring the "Justice" human SOUL from Undertale, Yellow sports a cowboy hat, a suit with boots, and a short mullet, and he primarily attacks the player with bullet patterns fired from a gun. Despite his well-meaning devotion to lawfulness and a stereotypical fixation on capturing "criminells," he is remarkably gullible and easily tricked by the party, leading to comedic moments where his warped sense of accountability even causes him to accept blame for things he didn't do.
