Dark Frights are small, feeble Dark Gaia monsters from Sonic Unleashed. They resemble balloon-shaped birds with small wings, a small knot on the bottom of their body and a little horn on their forehead. They have dark blue and black skin, and have markings on their body that resembles a face, while their actual black faces with yellow eyes are hidden inside their "mouths".
The Dark Frights are able to move around by either teleporting into an area in a puff of purple smoke, or emerging from black puddles on the ground. As a Dark Gaia minion, the Dark Frights can possess people by latching onto the deepest, darkest part of the heart, and generate despair, negative emotions or even erratic behaviour that are completely opposite to the person's personality.
The Dark Frights are capable of flight, allowing them to float through mid-air in any direction. They are also able to dash through mid-air at high speed.
