Fegan Floop is a television star who stars in his show, Floop's Fooglies. Though he seems to be the main antagonist for most of Spy Kids, he actually wishes to bring fun and happiness to children, and becomes an ally later on.
In Spy Kids, Floop is the host of his television show, Floop's Fooglies, of which Juni Cortez, one of the main protagonists, is a huge fan. At the same time, under the partnership of the evil disgruntled OSS employee, Alexander Minion, he is forced to create an army for the sinister Lisp. Floop and Minion make a machine that mutates agents, which Floop used as his Fooglies, otherwise known as his henchmen. Floop also invented Thumb-Thumbs, robots with thumbs as their limbs and heads.
Floop demonstrates to Lisp two of the robot children he has created, which Lisp requested for his evil army of robots. Lisp gives Floop and Minion a two-day deadline to complete the army.
While finding the Third Brain that will make the robots as intelligent as the best spies, Floop has another problem. He knows something is missing from his show but can't figure it out. Eventually, the Third Brain is brought to him by two robot children, who resemble Juni and his older sister Carmen Cortez. Floop then admits that he didn't really want to go with the plan and it was all Minion's idea. Minion then reveals his identity and orders the Robot Children to lock Floop up in the virtual room where his show usually takes place.
The real Juni ends up in the virtual room as well, while trying to find his parents. Floop reveals to him that he was only a pawn and that Minion is the mastermind. He even told Juni what Alex Minion and Lisp would do to him if he didn't do what they said. Next, he says that if he were to get out of the virtual room, he would reverse the damage he has done. Then Floop asks Juni if he knows the element that's missing from his show. Juni gives him the answer: It needs children. Juni then tosses his electric gumball at Floop, getting him out of the virtual room.
Floop freed Juni's family, and joined them in their mission against Minion and Lisp. They manage to capture Minion and turn him into a Fooglie. Immediately, they ran to the main control center. Carmen and Juni convince Floop to program the robot children to have minds of their own.
Floop succeeds in reprogramming the robot children. Later, the robot children are used in doing good deeds. Floop now has Minion and the robot versions of Carmen and Juni as his cast for his TV show.
