The blue petals on its back can rarely be used for flight. It only ever usually flies when it needs to switch location after devouring all available prey in its current place.In-game description
The Creeper is the Stage 3 power-magic form of the Ruin group.
Creepers were removed from the game before it was released, so although their data still exists, they do not appear anywhere.
A Creeper should evolve from Demiphage, but it is disabled in the alpha version. It cannot evolve anymore.
