The new home of the beachside city, the Emerald City, Knuckles lives on Angel Summit (commonly Holy Summit from Sonic Battle). Used get away from city life.

Personality
Knuckles is a coldly honest, independent, tough, somewhat gullible and short-tempered echidna with a one-track mind. Like how Sonic embodies the wind, Knuckles embodies the mountain; stern, unmovable and anchored to his duty. Due to having grown up on the isolated Angel Island and having been devoted to his sworn duty of protecting the Master Emerald for as long as he can remember, Knuckles has lived much of his life in seclusion and has become a rather antisocial, reclusive individual and a loner by nature. As such, he cares very little about what others thinks, which makes him bluntly honest and somewhat egotistical in the face of others.

Knuckles is fiercely loyal to his homeland, and does whatever is in his power to protect it and the Master Emerald. He prefers to stay close to the island's current emerald shrine to keep a watchful eye over everything on his home in order to maintain peace. Despite this, however, Knuckles is often willing to go with Sonic and company on their adventures whenever his help is needed, or when he feels the Master Emerald and Angel Island will be safe. Though Knuckles has been known to find other lifestyles appealing, he would never trade away his duties as he is far too devoted to his role as guardian of Angel Island and the Master Emerald. Whenever he is not focusing on his duty, Knuckles spends his time practicing his fighting skills, going treasure hunting or sometimes go hanging out with his friends.
