Professor Charles Xavier is the telepathic founder of the X-Men in Marvel Comics, later widely known through the X-Men animated series and live action films. This ahhhhh scream clip is shared detached from any single scene, circulating on meme soundboards and in edited videos as a generic reaction for psychic pain, overload and melodramatic suffering. Its popularity comes from the contrast between Xavier's normally calm, authoritative character and this panicked yell, making it instantly recognisable to superhero fans while still working as a funny scream for viewers who do not know the exact source.
