Fantomcat was an animated series produced by Cosgrove Hall Films. It was first broadcast in 1995 and was animated after Avenger Penguins in 1994 by Alfonso Productions, a Spanish animation studio. It aired largely on Children's ITV. The series also had a brief run on Pop and on Network Ten in Australia. It was produced and directed by Ben Turner.

Fantomcat centres on the character Phillipe Lentheric Guerlain de Givenchy, the Duke of Fantom, a masked swashbuckling hero who thrived in 1699, in mortal combat with his archnemesis Baron Von Skeltar. De Fantom was treacherously cast into a painting within the halls of his house, Castle De Fantom, and became trapped for centuries. As time passed, the area around Castle De Fantom became a bustling metropolis called Metro City, a city submerged in crime rings led by the fiendish arachnid Marmagora.

La serie televisiva è incentrata sul personaggio del Duca Filippo, un eroe spavaldo e mascherato che senza paura si unisce ad una agenzia investigativa. Con la sua spada, che può rispondere al suo richiamo, ed il suo anello, può renderlo invisibile, si oppone al male nel corso dei secoli.
