Nigauriman's design is pretty straightforward—he's literally based on the bitter melon fruit. His head is shaped like one, and his whole outfit reflects that theme: he rocks a dark hat, an orange and green shirt that mimics the fruit's bumpy pattern, tan pants, and dark red shoes. Oh, and he carries a white guitar, which isn't just for show.
Power-wise, he can spawn bitter melon fruits and shoot bitter melon juice through that guitar of his. It's an oddly specific skill set, but it works for the character.
