Dark Giant

The Dark Giants are magical creatures introduced in Season 8.

Overview
The dark giants are large monsters created by Valtor's dark magic.

Appearance
They are large, dark violet giants with bright indigo details.

Season 8
In "Surprise Party on Earth"' Valtor summons the Dark Giants to attack Gardenia Beach from the sea. They make their way through the waters towards the beach.

In "Valtor's Shadow", they continue their journey, destroying the off-shore oil rig. Nex and Brandon attempt to use Photon detonators on them, though they only flinch a little before proceeding to Gardenia Beach. Twinkly gives Sky one of the star core prototypes Orion developed, and uses it successfully against the closer Dark Giant, though the other one continues on its way. It reaches the beach and tries to grab Mike and Vanessa, though the Winx successfully rekindles the core, burning the giant.

Magical Abilities
They are resistant to many forms of physical attacks, being only destroyed by the power of star cores. They can shoot out destructive laser beams out of their eye.

Trivia

 * They are summoned from the sea. This may indicate that they are of aquatic origin.
