For boss information, see Flea (Monster).
Flea is a comrade of Ozzie and Slash, and a formidable opponent and wielder of magic. A crossdresser, Flea would have others believe that he is a woman, and perpretrates this myth with the bust-padding Flea Vest. He is possibly transgender. Possessing a taunting, cutesy sense of humor (more exaggerated in the Japanese version), he ridicules Frog about the death of Cyrus, and in Ozzie's Fort calls Magus a traitor.
Flea makes an appearance at the Bend of Time with Ozzie and Slash. According to Masato Kato at May 2022 - Chrono Cross Radical Dreamers Edition Questions and Answers, the Mystical Knights were summoned there.
Flea's Japanese name is a pun on Mayonnaise. His American name refers to the bassist of the Red Hot Chili Peppers.
