He is a two-tailed anthropomorphic fox with seven mechanical tails and is an alternate version of Miles "Tails" Prower from another dimension, who resided underground in New Yoke City[1], until finally building his own home in The Grim, which is where he currently resides.[2] Nine is one of the three different variations of Tails who was created when Sonic shattered the Paradox Prism.
