How much hp does nidhogg?

Nidhogg, the dragon from Norse mythology, is not typically quantified in terms of horsepower (hp) as it is a mythical creature rather than a machine. In various interpretations and adaptations, Nidhogg is depicted as a powerful being associated with the underworld, but specific statistics like hp are not part of traditional lore. If you're referring to a specific game or context where Nidhogg is assigned a hp value, please provide more details for a more accurate answer.
