Our fanart cartoon cursor with Boris Mettle features a minor character in OK K.O.! Let's Be Heroes, introduced as one of Enid's little brothers. Boris has a round, stout body with short limbs, similar to his brother. He resembles a Frankenstein monster due to his green skin and a massive stitched mark across his forehead, with screws on each side of his head. The boy features spiky, dark green hair on his head. He is seen wearing a purple jacket, a green-striped shirt, grey pants, and black shoes.
