Sonic and Jet are both one with the wind. However... Sonic is the Knight of the Wind, while Jet is the Legendary Wind Master. Sonic says "I have no master, except the wind that blows freely" while Jet claims to BE the master of the wind it self. Sonic serves the wind, Jet makes the wind serve himself. Therefor, Jet frames himself as a "Master" above Sonic.

So, Jet is the Master-Sonic? I'm not sure about this term, since it makes me think of the Master Emerald, which is the Anti-Chaos Emerald as Knuckles is the Anti-Sonic... But, other than that, I guess it makes sense.

Tails is the Kid trying to catch up to Sonic, Jet is the Master that tells Sonic "Catch Me If You Can". Tails is the Kid-Sonic, Jet is the Master-Sonic.

Tails: Kid Soniic
Amy: Girl Sonic
Knuckles: Anti Sonic
Blaze: Nega Sonic
Jet: Master Sonic
