The series takes place on Eternia, a planet of magic, myth, and fantasy. Its lead character is Prince Adam, the young son of Eternia’s rulers, King Randor and Queen Marlena. Whenever Prince Adam holds the Sword of Power aloft and proclaims “By the Power of Grayskull!” he is endowed with “fabulous secret powers” and transformed into He-Man, the most powerful man in the universe. Together with his close allies, Battle Cat (who undergoes a similar transformation from being Adam’s cowardly pet tiger Cringer), The Sorceress, Teela, Man-At-Arms, and Orko, He-Man uses his powers to defend Eternia from the evil forces of Skeletor. Skeletor’s main goal is to conquer the mysterious fortress of Castle Grayskull, from which He-Man draws his powers. If successful, Skeletor would have enough power to rule all of Eternia and possibly the entire universe.

To his family’s frustration, Henry is skilled at making trouble, from babysitting pets in his bedroom to starting a shark panic at the swimming pool. He is a mischievous prankster-type kid, who is exhilarant and arrogant. He is much hated by some of the staff at Ashton Primary School (his school), like Miss Battle-Axe and Mr Soggington but is a very popular kid with the students, having lots of friends, most likely due to his prankster-type personality.

That jumbled piece of architecture, that cacophony of hissing steam and creaking joints, with smoke billowing from it as it moves on its own… That castle is home to the magnificent wizard Howl, infamous for both his magical prowess and for being a womanizer—or so the rumor goes in Sophie Hatter’s small town. Sophie, as the plain daughter of a hatmaker, does not expect much from her future and is content with working hard in the shop.

Hulk, She-Hulk, Red Hulk, A-Bomb, and Skaar come together as the Agents of S.M.A.S.H. to tackle threats that no other superheroes can face. The Agents of S.M.A.S.H. have their base near the town of Vista Verde (where Bruce Banner first became Hulk) and often face various threats with a recurring one being from Hulk’s archenemy Leader.
