Powers & Abilities
Like most Skrulls, Skymax is a shape-changer and can take any shape he desires, which allows him to perfectly impersonate individuals. Unlike most Skrulls he went through the Super-Skull program giving him a few abilities that surpass that of the average Skrull, most notably used by the Fantastic Four, with the exception that Skymax can use all of the team's abilities. Among those abilities are super strength, durability and flight as well as becoming invisible and having the ability to project flames from his body, particularly his fists.
