ok if i have, Impervious and i have the Infinity Gauntlet and it has the time gem on "Super Senses" do i get to roll 2 die one for the Impervious
and one for Super Senses.

Yes you would. This would be similar to Unus the Untouchables power.
You'd have to roll the Supresenses first of course.

Correct, you roll the first D6 for Super Senses to see if the attack is evaded. If the attack is not evaded by Super Senses you then Roll to see if damage is reduced to 0 by impervious.
