The Super-Skrull (Kl'rt) is a fictional character appearing in American comic books published by Marvel Comics. The character, created by Stan Lee and Jack Kirby, first appeared in Fantastic Four #18 (September 1963).
Kl'rt can shapeshift (like all Skrulls) but, thanks to his re-engineering by Skrull scientists, he has versions of the Fantastic Four's superpowers. These include greater malleability; superhuman strength, stamina and durability; flight, heat manipulation and energy projection (in the forms of plasma, concussive force and anti-matter blasts); invisibility and the creation of invisible force fields. He has developed his expertise over time. The Super-Skrull also has a unique power: the ability to control the minds of others or paralyze them by emitting hypnotic force from his eyes.
