## In other media
### Marvel Cinematic Universe

Kaecilius appears in media set in the Marvel Cinematic Universe (MCU):
* Kaecilius appears in Doctor Strange, portrayed by Mads Mikkelsen. A combination of several villains from the comics, Kaecilius was used in the film to drive the introduction and development of bigger villains for the future, including Dormammu and "certain individuals who live in other dimensions". This version was motivated to become a Master of the Mystic Arts after the death of his family, became disillusioned with what he considered the Ancient One's hypocrisy, and subsequently chose to serve Dormammu by using the same life-extending ritual his former master used to channel the Dark Dimension's energy. Believing in Dormammu's promise of eternal life, Kaecilius and his zealot followers destroy the Masters of the Mystic Arts' Sanctums to allow the Dark Dimension to consume Earth. However, Doctor Strange convinces Dormammu to renounce his attack on Earth, after which he drags Kaecilius and his followers into the Dark Dimension.
* An alternate universe variant of the incarnation of Kaecilius appears in the What If...? episode "What If... Howard the Duck Got Hitched?", voiced by Jared Butler. He managed to take over the Collector's operations by sending him to the Mirror Dimension. Yondu learned of that when he brought the egg containing Howard the Duck and Darcy Lewis' unhatched child to him. Kaecilius had his followers kill Yondu. Then he does a ritual that would enable Dormammu to take the unhatched child as a host only for Howard the Duck and Darcy to foil it. Kaecilius and his followers soon went after the egg while competing against Grandmaster, Laufey, Malekith, Zeus, Thanos, and the Black Order. When the egg turned golden, Kaecilius is among those that were subdued by its golden energies while Zeus fled and Laufey withdrew from pursuing it.
