JumpStart Spy Masters

JumpStart Spy Masters is a sub-series of JumpStart released in 2001 designed for ages 7-11 (roughly 3rd - 5th Grade). It contains two games: There is also a demo version called JumpStart Spy Masters Training Mission which came on the same disc as JumpStart Music and was distributed as part of a promotion by Great Clips.
 * JumpStart Spy Masters: Unmask the Prankster
 * JumpStart Spy Masters: Max Strikes Back

As the second game ends without resolution to major plot points, it is likely the series was meant to continue longer.

Adventurers (Spy Masters)
The main protagonists of the game series; consist of characters from the JumpStart Adventures games.
 * Botley/Android XL2 (Dee Bradley Baker): From JumpStart Adventures 3rd Grade: Mystery Mountain; he's in charge of the computers at HQ.
 * Thomas "TJ" James Adams (Brianne Siddal): From JumpStart Adventures 4th Grade: Sapphire Falls; the newest member of the Adventurers.
 * Sally Chu (Kim Mei Guest): Also from JumpStart Adventures 4th Grade: Sapphire Falls.
 * Jo Hammet (Paula Tiso): From JumpStart Adventures 5th Grade: Jo Hammet, Kid Detective.
 * Zack (Phil Synder): From JumpStart Adventures 6th Grade: Mission Earthquest; probably head of the Adventurers.
 * Jess (Paula Tiso): Also from JumpStart 6th Grade: Mission Earthquest; Zack's sister & probably second-in-command of the Adventurers.
 * Omega: The red-eyed replicate of Alpha; it was created by Max as part of his "back-up plan in case went wrong with Alpha". It was found by TJ when the Adventurers were at Max's Hideout in Unmask the Prankster. It is currently being used by the Adventurers to help get computer access.

Villains

 * Max Masters/Prankster (Dee Bradley Baker): The main antagonist in the two games. Max used to be the youngest Adventurer until he was kicked out because of his refusal to cooperate. In Unmask the Prankster, he disguises himself as the "Prankster" & plays pranks on (or tries to get revenge against) the Adventurers as the Prankster. He later gets his revenge in Max Strikes Back, although he rejoins & helps the Adventurers at the end of the game, just to find out who framed him.
 * Alpha: A small magenta-eyed robot that was created by Max in order for him to have access to the Adventurers' computers at HQ. It was (accidentally) destroyed by Max at the end of Unmask the Prankster.
 * Dr. X (Lex Lang): From JumpStart Adventures 5th Grade: Jo Hammet, Kid Detective; he didn't appear or was mentioned in either games but his name was seen in the credits. It is possible he may have played a role in the games had the series continued.
