OK first of all (don't take this the wrong way) Tails is actually pretty immuature and even sometimes facetacius. I'd have to Omega because he is even more mature that the other characters you have listed, followed by Tails' Farther, Sally, Black Doom and Mephilis or however you spell it.

Tails is humerous, passive, shy at times and is easily manipulated by characters like Fiona and Rouge
