Sydney, along with Kirby Kowalski and Butch, were unwillingly bonded to evil Ultralinks. Since they were being mind-controlled, they attacked Maxwell and Steel, who were trying to help them. Afterwards, the trio escapes to the sewers. With Ven-Ghan's help, Max tracks them down and once again attempts to save them.
After a scuffle, Max and Ven-Ghan wound up at an empty water reservoir, where a Makino Deployer teleported to rescue the Ultralink trio. Sydney and the Ultralink's bond is temporarily debilitated after Max remembers about who she was. Once she regains her conscience, Sydney stops Butch Link from attacking Max and is ultimately unlinked by Ven-Ghan.
Abilities
Superhuman Durability: Sydney's body is protected by a durable armor.
Energy Rays: Sydney Link can shoot pink lasers from her hands or the large tentacles sprouting from her back. They were powerful enough to temporarily take down Max in his Turbo Strength Mode.
Levitation: Sydney can levitate objects with her energy rays, as exemplified when she levitated several cars.
Appearance
Sydney Link has a hunched over posture and has the Ultralink fixed on her face. She has a pink armor plate attached to the top of her head, pink and silver armor wrapped around her upper torso and two large tentacles sprouting from her back. Her arms are protected by a silver armor, with her left forearm having a pink gauntlet. She has armored sections on the thighs and pink and silver armor on the shins.
Personality
Like other Ultralinks, she blindly followed Makino's orders and wished to reunite with the rest of the Ultralink soldiers. When Max attempted to bring Sydney back to her senses, she ignored and even laughed before attacking him.
Trivia
Sydney Link is the second villainess introduced in the series, with the first being Toxziana.
Not counting Knockout, Power Wing and Quickfire, who only appeared in the graphic novels, Sydney Link, Kirby Link and Butch Link were the only teenager villains in the entire series.
