After the exposure to Terrigen Mist, Raina has got spikes all over her head, but it's merely her physical appearance. It's by no means her superpowers. In the last episode S01E17 of Marvel's Agents of S.H.I.E.L.D., Gordon assured Raina that she would soon come to know about her gift. It means the TV show hasn't revealed her superpowers yet.
Is there any official statement on this?
Is there any Raina equivalent in the comics? If yes, what are her superpowers?
