So like Force projection or Physiological perfection. I dont mind the psionic powers for M if she is considered a psionic who powers are focused through her physical body. I think her being a psionic energy transducer could explain her abilities. I mean it seems all St. Croix are some what psionic with other powers but they also have a very strong physical mutation i.e. the merging. I would might have that be a secondary mutation that each has.
