Nidhogg

"Those who are bound to a human - Trainer - will never have my approval."

Nidhogg is a Sceptile-Lycanroc fusion, specifically the Midnight form. His father was the famous Hoenn Champion's starter Pokemon, a Sceptile, who came over to Alola for a vacation, who met his mother which is a shiny Lycanroc. He was an illegitimate child, his parents left him alone before he hatches. He then was raised by all sorts of wild Pokemon in Akala Island, though he moves around a lot and doesn't stay in one place.

He doesn't trust human, or any Pokemon who has a Trainer.

Nidhogg is close to Ginny, a blind Gible who tags along with him. He has vowed to make Ginny's dream come true.
