Nikki is the son of Nico Savoy and Sallie Gold. He has a golden retriever appearance with gold and white fur and turquoise eyes, with yellow sclera.
Nikki was born on Halloween night alongside his sister and cousins, a year after his parents were married. He was a wild and rather destructive child.
As a child, Nikki was shy but liked to be a little jokester. He enjoyed fixing things and helping his friends, something his father and aunt encouraged, claiming it would toughen him up.
As a teen, Nikki managed to mature himself into being more responsible and not so reckless. However, he still keeps his humorous and jokester side in store.
As a young adult, Nikki became the muscle for Marigold.
Nikki is a brave, daring, and intelligent boy. He is a skilled rapper and wrestler. He enjoys fishing and tangling with his brother and father or anyone who would dare challenge him. Despite his rowdiness, Nikki is a friendly and good-natured boy.
