Valdez

Valdez haled from the Dragon Kingdom as a member of the Shinobi Clan, serving as mentor to Espio the Chameleon. He was assigned the duty of spying on Locke and his dealings with the Kingdom of Acorn by his clan before Locke joined the Brotherhood of Guardians, and afterwards helped Espio settle into Rainbow Valley to take over his duties when Knuckles became Guardian.

Following the retirement of Fleming, Geoffrey assumed command of the Secret Service. From there, King Maximillian Acorn ordered him to recruit new members to begin a mission to discover what had become of Queen Alicia Acorn during the Great War. Valdez was personally chosen by Geoffrey to join his team, as he had apparently worked for the Secret Service previously. While he initially seemed somewhat resentful when Geoffrey tracked him down (mentioning that Espio had told him the skunk had been seen on the island), he nevertheless rejoined.

During their first training mission, Valdez went into a water tank which Hershey Cat had recently fallen into, and threw Bomb at an approaching robotic shark, saving Hershey. When Geoffrey explained the hard training up ahead, Valdez whispered to the other trainees "Why do I get the feeling I should have stayed in bed?"

In their next training mission, Valdez was responsible for taking out the security sensors on the building which they were to enter. Next, he took out the sole SWATbot guard of the facility. Following this training mission, Valdez and the other trainees were official recruits of the Secret Service.

For their first official mission, Valdez and the others went to Angel Island where they discovered what had become of Queen Alicia after her convey was shot down while flying to the neutral territory of Angel Island during the Great War. Valdez was taken by surprise at the bizarre weather patterns that the island was experiencing due to the most recent of the Days of Fury, but after recognizing some snow covered structures as pyramids, he determined that they had landed in the Sandopolis Zone and was able to provide his team with some orientation. After arriving at the Royal Compound and discovering Prince Elias, the Queen's son, they later were taken to Haven where Queen Alicia was discovered in stasis. The group retrieved the comatose Queen and brought her and Elias back to Mobotropolis.

When Dr. Eggman began retaking Mobotropolis after luring the Knothole Freedom Fighters to his satellite station, Valdez held off a group of Shadowbots, allowing his friends to escape with Rosie and her orphans. His fate remained unknown for some time until Hershey Cat snuck into the re-christened Robotropolis and discovered he had been roboticized.

Following Valdez's capture by Shadowbots in Mobotropolis, Dr. Eggman, surprised to find a chameleon not on Angel Island, decided he would be useful. Not wanting merely another Robian slave, Eggman gave Valdez special reprogramming to twist his real memories. Valdez came to believe that the Secret Service had abandoned him and that Eggman had saved his life. Believing that Eggman needed the Chaos Emerald to defeat an evil King Acorn and prevent the echidnas from using its power for world conquest, Valdez was dispatched to Angel Island, acting as the doctor's lieutenant for the area. Once on Angel Island, Valdez approached his former village and demanded to see Espio. Having been passing through the area with Julie-Su, Liza, a female chameleon, found Espio and brought him to Valdez, saying he wished to see him. Espio was shocked to find his old friend roboticized.

After Espio was captured and brought aboard the transport ship, Valdez explained how the Secret Service had betrayed him and how he was saved by Eggman. When Espio showed doubt at this turn of events, Valdez became enraged, as he'd thought that Espio would side with him as his friend. He had a struggling Liza brought in. When Espio asked Liza why she had brought him to Valdez, Liza explained through tears that she'd hoped he could reason with Valdez. Through his twisted point of view, Valdez accused Liza too of betrayal, saying that she'd always preferred Espio to him. Thus, he had Liza roboticized, and threatened to have the rest of the Chameleons roboticized as well if Espio did not help him to locate the Master Emerald. Throughout all this, he repeatedly addressed Espio as "friend."

Espio, caught between the options of allowing his people to be roboticized, or betraying Knuckles, attempted to deceive Valdez into releasing the Chameleons before he helped them. Valdez flatly refused, telling Espio if he did not help them immediately, the other Chameleons would be roboticized. Upset at Valdez's behavior, Espio said he'd help. Espio then led Valdez, Liza and a group of Shadowbots to the remains of a city, lying to Valdez about them having visited Knuckles and the Chaos Emeralds there years ago. Valdez, unable to recall the memory, dismissed it and reinforced his threat: if Espio tried to pull a fast one on him, the chameleons captive on the ship would be roboticized. However, once within the ruins, Espio disappeared from view. Looking for him, Valdez stepped upon a trap door and was dropped below to the sewer system, isolated from the others. Valdez once again threatened his "friend" for his deceit, leading Espio to yell "Don't call me your friend! Not anymore!" Espio sent them both into the water and they got into a struggle, Valdez attempting to reach the ship's remote trigger on his arm. What exactly happened is unseen, as Liza and the Shadowbots were unable to detect either Valdez or Espio in the water, and while they continued to search, Espio freed the rest of the Chameleons from the ship; it exploded as they left. When one of the chameleons asked what had happened to Valdez, Espio simply replied that they wouldn't be seeing him again.
