Accidental Aesop: The treatment of the movie villains ends up making a commentary about how to deal with criminals. Rather than being locked away, they are rehabilitated and put to work in society, and are actually helpful in subsequent movies, while in the third movie the Toymaker was turned bitter and world-conquering because of his imprisonment, and gives up on his ambitions upon being shown humanity and forgiveness. Armageddon then drops the "accidental" part entirely, making it a plot point.
Alternative Character Interpretation: With its agents constantly going rogue, and its use of children for dangerous missions, it's not hard to argue that the OSS are corrupt and villainous, particularly when Juni decides to quit being an OSS agent after seeing how some of their top agents are expected to act.
Big-Lipped Alligator Moment: Both the first and second film end with a post-credits scene, the first being a shot of inside Floop's castle and the second of the treehouse. Nothing happens in either sequence.
Magnificent Bastard: Alexander Minion is the affable, humorous mastermind of the "Spy Kids" plot, playing the part of a put-upon lackey to Fegan Floop to hide his truly brilliant colors. Capturing and mutating a variety of OSS secret agents to whittle down enemy opposition before creating an army of robotic doppelganger children, Minion builds Floop up as a figurehead to gain funding for his plans and keep suspicion off his double dealings. Minion uses his knowledge as a former OSS agent to capture even the skilled Cortez agents, deduces the location of the legendary Third Brain, then steals it from the Cortez kids to perfect his "Spy Kids", after which Minion betrays Floop and asserts himself as the film's true villain. Minion's resolve is so great that he faces capture and defeat with brevity, and allows himself to be monstrously mutated to continue his schemes. When beaten, Minion simply takes on a side gig as Floop's TV partner and becomes a close ally to the Cortez family, accepting his ultimate fate as a suitable living.
