Cygnus Returns (full animated intro)

its not entirely impossible [MENTION=5228]Razmos[/MENTION];
Maybe she innately has water powers and unlocked it due to overwhelming sadness of her tears.. and that water barrier proves my point.
Water is also known as an element closely related to healing. It only makes sense that her water powers were responsible for shinsoo's resurrection.

I'm not saying that Cygnus's powers weren't water based in the trailer, she used a water barrier to heal Shinsoo, yes.
It makes sense for Cygnus to have the power of ALL the elements, because the Cygnus Knights draw their power from her. While it makes sense that she uses a water based ability to heal Shinsoo, using this as a basis to speculate that ALL the Cyngus Knights will be water based is just silly.
