Rogue, Gamora,Cyclops and other similar charaters

[firbison]

These said characters have super powers that allow dice to be rolled for the effect to happen but since dice are being rolled there was never a clear answer to if you get to roll extra dice for a critical. Do super powers that roll dice that are not an attack roll said extra dice.

rogue/ mutant absorption

cassandra nova/ psychic distraction 

gamora/ martial prowess 

cyclops/ quick draw

etc...

[Negoldar]

Critical results generate additional dice for attack, defense, and dodge rolls. They otherwise will not generate additional dice. 

Of the rules you listed, only Martial Prowess (Gamora) and Quick Draw (Cyclops) will generate additional dice as they modify how the defense dice pool is created.
