Darcy

Darcy is the middle sister of the Trix, a trio of witches who are the main antagonists in both the television series and comics.

Darcy is often referred to as the "Queen of Darkness" or "Lady of Darkness". Her powers revolve around physical and metaphorical darkness, illusion, hypnotism and confusion.

Personality
Darcy is a devious, manipulative and highly intelligent witch. Instead of attacking offensively, Darcy prefers to mentally control and/or confuse her enemies, capitalising on and exploiting their weaknesses. She can thus be viewed as the least agressive but most powerful member of the Trix.

While Darcy shares her sisters' lust for power, she is more cautious in her quest for it.

Season 1
In the first seson, Darcy and her sisters seek to control the power of the Dragon Flame, which they initialy believe in contained within the Sword Ring. Using her powers of deception and disguise, Darcy is able to sucessfully steal the ring in Episode 5.

Darcy later uses Riven, whom she places "under her spell", to spy on the Winx and relay information about their activities. In Episode 10, Darcy is able to sabotage the Simulator after Riven relays that Bloom will taking a test in it.
