The X-Men are a team of mutant superheroes in the Marvel Universe. They were created by writer Stan Lee and artist Jack Kirby, and first appeared in The X-Men #1 (September 1963). The basic concept of the X-Men is that under a cloud of increasing anti-mutant sentiment, Professor Xavier created a haven at his Westchester mansion to train young mutants to use their powers for the benefit of humanity, and to prove mutants can be heroes. Xavier recruited Cyclops, Iceman, Angel, Beast, and Marvel Girl, calling them "X-Men" because they possess special powers due to their possession of the "X-gene," a gene which normal humans lack and which gives mutants their abilities. However, early on, the "X" in X-Men stood for "extra" power which normal humans lacked. It was also alluded to that mutations occurred as a result of radiation exposure. The comic was partially inspired by the African-American civil rights movement of the 1960s. The first issue also introduced the team's archenemy, Magneto, who would continue to battle the X-Men for decades throughout the comic book's history, both on his own and with his Brotherhood of Mutants. The X-Men universe also includes such notable heroes as Wolverine, Storm, Colossus, Emma Frost, Gambit, Nightcrawler, Rogue, Psylocke and Shadowcat. Other villains that the X-Men have fought include the Sentinels, Apocalypse, Mister Sinister, the Marauders, the Acolytes, the Hellfire Club, and the Purifiers. The X-Men comic books have also been adapted into other media, including animated television series, films, and video games.

The X-Men are a fictional team of superheroes that appears in American comic books published by Marvel Comics. The X-Men were created by writer Stan Lee and artist Jack Kirby, and were first published in 1963. They are among Marvel Comics' most popular and lucrative intellectual properties, appearing in numerous books, television shows, films, and video games.

Xena is a fictional character from Robert Tapert's Xena: Warrior Princess franchise. She first appeared in the 1995–1999 television series Hercules: The Legendary Journeys, before going on to appear in Xena: Warrior Princess TV show and subsequent comic book of the same name. The Warrior Princess has also appeared in the spin-off animated movie The Battle for Mount Olympus, as well as numerous non-canon expanded universe material, such as books and video games. Xena was played by New Zealand actress Lucy Lawless, who commonly wore a tight leather skirted outfit overlaid with metal armor. Xena is the protagonist of the story, and the series depicts her on a quest to redeem herself for her dark past by using her formidable fighting skills to help people. Xena was raised as the daughter of Cyrene and Atrius in Amphipolis, though the episode "The Furies" raised the possibility that Ares might be Xena's biological father, but it is never pursued further. She had two brothers, the younger of who is dead; she visits his grave to speak with him in "Sins of the Past." In Hercules: The Legendary Journeys, during her two first episodes, Xena was a villain, but in the third episode she appears in, she joins Hercules to defeat Darphus, who had taken her army. Aware that the character of Xena had been very successful with the public in the three Hercules: The Legendary Journeys episodes, the producers of the series decided to create a spin-off series based on her adventures. Later in Xena: Warrior Princess she is joined by Gabrielle, a small town bard. Together they go up against ruthless warlords and Gods in the ancient mythological world. The character Gabrielle, introduced in the first episode, becomes Xena's greatest ally and best friend; her initial naïveté helps to balance Xena and assists her in recognizing and pursuing the "greater good."

Yogi Bear is a family cartoon character who has appeared in numerous comic books, animated television shows and films. He made his debut in 1958 as a supporting character in The Huckleberry Hound Show. Yogi Bear was the first breakout character created by Hanna-Barbera and was eventually more popular than Huckleberry Hound. In January 1961, he was given his own show, The Yogi Bear Show, sponsored by Kellogg's, which included the segments Snagglepuss and Yakky Doodle. Hokey Wolf replaced his segment on The Huckleberry Hound Show. A musical animated feature film, Hey There, It's Yogi Bear!, was produced in 1964. Yogi was one of several Hanna-Barbera characters to have a collar. This allowed animators to keep his body static, redrawing only his head in each frame when he spoke. This reduced the number of drawings needed for a seven-minute cartoon from around 14,000 to around 2,000.
