Question: Who is the principal character of a series of comic books and several animated television series, characterized by his superhuman strength?
Context: Gamora Zen Whoberi Ben Titan ( ) is a fictional character appearing in American comic books published by Marvel Comics.  Created by Jim Starlin, the character first appeared in "Strange Tales" #180 (June 1975).  Gamora is the adopted daughter of Thanos, and the last of her species.  Her powers include superhuman strength and agility and an accelerated healing factor.  She also is an elite combatant, being able to best most of the opponents in the galaxy.  She is a member of the group known as the Infinity Watch.  The character played a role in the 2007 crossover comic book event "", and became a member of the titular team in its spin-off comic, "Guardians of the Galaxy".  She has been featured in a variety of associated Marvel merchandise.  Zoe Saldana plays the character in the 2014 live-action film "Guardians of the Galaxy" and its sequel "Guardians of the Galaxy Vol.  2". He-Man is the principal character of a series of comic books and several animated television series, characterized by his superhuman strength.  In most variations, he is the alter ego of Prince Adam.  He-Man and his friends attempt to defend the realm of Eternia and the secrets of Castle Grayskull from the evil forces of Skeletor. Hulkling (Dorrek VIII, also known as Theodore "Teddy" Altman) is a fictional superhero appearing in American comic books published by Marvel Comics.  The character has been depicted as a member of the Young Avengers, a team of superheroes in the Marvel Universe.  Hulkling's character is patterned on the Hulk.  He has shapeshifting abilities that go far beyond the ability to mimic the Hulk, and superhuman strength. Doug Howard (born May 2, 1956) is an American bassist, vocalist and songwriter.  He is best known for his work as a performing/recording musician and occasional co-writer with groups, and artists such as Touch, Stun Leer, Todd Rundgren, Utopia and The Edgar Winter Group.  He also played the role as the singing narrator "Songster" in the 1987 live production of the Masters of the Universe Power Tour based upon the Mattel He-Man series action figures.  Howard is also the managing partner of Lodestar Entertainment, LLC, a music and video licensing, and publishing company based in New York.  He is the paternal grandson of the American songwriter Joseph E. Howard, composer of "Hello!  Ma Baby," "I Wonder Who's Kissing Her Now" and "Good-bye My Lady Love," among other titles. Asterix and Obelix is a French live-action film franchise, based on the comic book series of the same name by French comic book artists Albert Uderzo and Rene Goscinny.  The series includes four theatrically released films.  Just like the comic books, the films focus on the adventures of Asterix and Obelix, two Gauls in Roman-occupied Europe.  With the help of a magic potion which causes superhuman strength, the Gaul's tiny village manages to resist Rome. Superhuman qualities are qualities that exceed those found in humans. Superhuman abilities are found in some fictional characters, especially as superheroes in American comic books. Fictional characters have been portrayed as having psychic abilities, flying abilities, impossible strength, or exceptional proficiency beyond human capability.  "Superhuman" can also mean something that is not human, but considered to be "superior" to humans in some way, e.g. a tiger may be described as having "superhuman strength". Popeye the Sailor is an American animated series of comedy short films based on the titular comic strip character created by E. C. Segar.  In 1933, Max and Dave Fleischer's Fleischer Studios adapted Segar's characters into a series of "Popeye the Sailor" theatrical cartoon shorts for Paramount Pictures.  The plotlines in the animated cartoons tended to be simpler than those presented in the comic strips, and the characters slightly different.  A villain, usually Bluto, makes a move on Popeye's "sweetie," Olive Oyl.  The villain clobbers Popeye until he eats spinach, giving him superhuman strength.  Thus empowered, the sailor makes short work of the villain. Captain Marvel, also known as Shazam ( ), is a fictional superhero appearing in American comic books published by DC Comics.  Artist C. C. Beck and writer Bill Parker created the character in 1939.  Captain Marvel first appeared in "Whiz Comics" #2 (cover-dated Feb. 1940), published by Fawcett Comics.  He is the alter ego of Billy Batson, a boy who, by speaking the magic word "SHAZAM" (acronym of six "immortal elders": Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury), can transform himself into a costumed adult with the powers of superhuman strength, speed, flight, and other abilities. A healing factor is the ability of some characters in fiction to recover from bodily injuries or disease at a superhuman rate.  Since the introduction of Wolverine by Marvel Comics in 1974 and inspired by the immense popularity of the character, superhuman healing has become a fairly common power featured in comic books, novels, television, film, and other media.  The overall efficiency of a character's healing factor often fluctuates due to various writers applying a very broad degree of artistic license.  Weapon X has been established, on multiple accounts for having the fastest healing factor over all mutants, with the exception of external factors.  As a result, especially concerning characters depicted in comic books, it has become a very common source of debate among fans.  Over the years, it has also become common for healing factors to have an umbrella effect, serving as a partial source for multiple superhuman abilities; various powers thus demonstrated include superhuman strength, speed, stamina, agility, reflexes, durability and/or senses, to name the most common.  The source of a character's healing factor, depending upon the medium, usually ranges from natural genetic mutation, accidental exposure to radioactive materials, artificially-induced genetic enhancement, cybernetic augmentation, magic or even a combination of different factors.  Despite the ability to quickly recover from wounds, characters with a healing factor are still capable of feeling pain. Obelix (Obélix in French) is a cartoon character and protagonist in the French comic book series Asterix.  He works as a menhir sculptor and deliveryman, and is Asterix's best friend.  Obelix is noted for his fatness, the menhirs he carries around on his back and his superhuman strength.  He fell into a cauldron of the Gauls' magic potion when he was a baby, causing him to be the only Gaul in Asterix's village who is in a permanent state of superhuman strength.  Because of this already enormous strength, Obelix is not allowed to drink the magic potion ever again, a ban he regards as being tremendously unfair.  Other characteristics are his simplemindedness, his love and care for his dog Dogmatix, his anger when someone refers to him as being ""fat"", his enthusiasm for hunting and eating wild boars and beating up Romans.  His catchphrase is: ""Ils sont fous ces romains"", which translates into "These Romans are crazy!" , although he considers nearly every other nationality to be just as strange.
