Vanya (Ellen Page) is initially told she doesn't have powers by Reginald (Colm Feore). She's led to believe she isn't special and is kept isolated from her siblings. It isn't until she stops taking her medicine in season one that her true power is unleashed; she's able to manipulate sound into nuclear-levels of energy. Suffering from amnesia without the baggage from her past, Vanya is able to unlock more of her power in season two. Vanya can apparently bring people back from the dead by passing her energy onto them, resulting in them being connected until she takes the energy back. She can also use her sound manipulation to float. Who knows what else Vanya will be able to do now that she knows who she is.
