Floyd is a fly who is part of the bugs from the Bug Trio from the episode "Doof 101" and the special "O.W.C.A. Files." He is every fry short of any happy meal.
Like the rest of the bugs, Floyd lives in Danville High School. He is first seen with Napoleon and Wendell spotting Heinz Doofenshmirtz giving his genetics lecture to the students. Napoleon suggests of having himself and his friends to become the first insects to communicate with humans, to which Wendell and Floyd agree. To do so, they would have to climb up to the table and hoist up a banner to greet the humans. Despite several difficulties, the bugs manage to make to the top of the table, but Napoleon is annoyed that Wendell and Floyd have misspelled their banner. As Napoleon berates the two for their stupidity, the bugs are then accidentally squashed by Doofenshmirtz's Evil Science 101 book, just as Doofenshmirtz finishes his lecture to the students before the bell rings. After Doofenshmirtz leaves with his daughter Vanessa, the bugs are revealed to have survived the book squash. ("Doof 101")
Floyd and his friends later try to apply to O.W.C.A. in person after their paper applications are lost among New Year's party confetti. During their attempt to gain the attention of O.W.C.A.'s administrators, Floyd temporarily became lucid after hitting his head, but upon hitting it again reverted to his usual state. Although inadvertently helping O.W.C.A.'s new agents defeat the infamous Professor Parenthesis, Floyd and his friends fail to be noticed and are last seen at the site of an impressive explosion. He also survives. ("O.W.C.A. Files")
