@Luma.dash- While I would say it is a "super state" for the sake of Team Super Sonic, it isn't Super Tails and Super Knuckles.

I understand why not Super Tails because he is a transformation from the Super Emeralds. I figured this is because Tails just cannot handle raw chaos energy that Sonic can to become Super, that or he requires more chaos energy just to ascend to Super-state. another reason I figured Tails and Knuckles cannot go Super anymore was simply Sonic Team wanted Super-state to be of rarity as an ability than like DragonBall where all Saiyans can just go Super Saiyan.

But just having male Hedgehogs be granted Super-states makes me think that is both unfair as well as more like DragonBall giving Super Saiyan is a racial thing. (Playable humans in Dragon Ball Online all have watered down saiyan genes and can use the dragonballs to wish for the ability to become Super Saiyans.)
