Donnagon Giggles is a character in the Action/Adventure film series Spy Kids, appearing in the first three films in which he was the main villain in the sequel Spy Kids 2: The Island of Lost Dreams. In the sequel Spy Kids 3-D: Game Over he was an ally to the characters and no longer a villain.
He was played by Mike Judge.
Spy Kids 2: The Island of Lost Dreams
The father of Gary Giggles and Gerti Giggles and double agent of the spy organization, The OSS. Carmen and Juni, spies and heroes, helped Donnagon escape in the first movie. However he's become the director of The OSS and plans to steal The Transmooker device to rule the world. He uses his son to setup and fire Juni and sends his kids to recover the device from an island near Madagascar.
But later, his daughter and the heroes destroy The Transmooker and he and Gregorio get into it. When the president and his daughter arrive at the island, they fire Donnagan.
Spy Kids 3-D: Game Over
Donnagon was "straightened out" by his wife and was back working with the OSS despite his betrayal and trying to kill the Cortez family. He along with his wife inform Juni on the Toymaker (the main villain of the third film) and his plot to enslave children's minds through his video game Game Over! as a revenge scheme against the OSS for imprisoning him for 30 years. Juni enters into the simulation of Game Over in order to save his sister.
- In the first Spy Kids his full name is given as Michael Donnagon as shown on his missing report.
- It is implied in dialogue that Donnagon had attempted to take over the world prior to the events of Spy Kids 2, although this was obviously not known to the OSS due to his promotion in that film.
