Cosmo scientist

Appearance: Cosmo has dark brown skin with vetiligo (white spots all over his body), and three moles on each cheek. Cosmo has black eyes and short, curly brown hair with bangs dyed white. Cosmo wears a white linen shirt, gray pants, and tall, dark gray boots. He also wears round, tinted glasses with straps.

Cosmo is Sprout's creator. He uses Sprout as an assistant, sending him on various small errands, and doesn't particularly care for him. He rarely praises Sprout and treats him like an object, although he isn't particularly rude to him.

Appearance: Light red skin. Half of his face, arms, and legs are green, and they are also sewn on, which reveals scars and stitches. He has sharp teeth, his right eye is black, and his left eye is blind and whiter and more faded. His hair is tousled and medium-length, green and red. Sprout has a large, heavy metal collar with a chain around his neck, and a matching bracelet on his left arm. His torso is covered in white, slightly dirty bandages that need to be changed frequently. Sprout also has a tail that resembles a long vine with leaves along its entire length. Sprout is also quite tall compared to Cosmo.

Sprout is a creation of Cosmo, assembled from various body parts of other deceased people. He is almost helpless and obeys Cosmo's instructions, believing that he is being watched over and protected.
