Nessie (ネッシー) is the legendary mysterious creature that dwells in Loch Ness. When Kinnikuman first hears of her and that she is believed to be 20 meters tall (shorter than his giant form), he decides challenge her to a fight on live TV. Unfortunately, she turns out to be much larger than his giant form and defeats him with a mere lick on the cheek. In the anime, she first plays around with him before knocking him into space. When Kinnikuman gets a garlic boost from Meat and tries to fight back, she ends up swallowing him and then later pooping him out as she leaves.
