Ultron (1968): Was created by Roy Thomas and John Buscema. The character is disguised for the majority of the issue as the Crimson Cowl, with his face only revealed on the last page of the issue and no name given to the character. The character leads the Masters of Evil against the Avengers, having hypnotized Edwin Jarvis into working for him. Further flashbacks reveal that Ultron is the creation of Hank Pym, and based on Pym's brain patterns. The robot gradually developed its own intelligence and rebelled, and almost immediately develops an Oedipus Complex, whereby it feels irrational hatred for his "father" Hank, and demonstrates an interest in Hank's lover Janet van Dyne, the Wasp. Rebuilding itself, learning how to turn itself on, and upgrading five times, Ultron then hypnotizes Pym and brainwashes him into forgetting that the robot had ever existed.
Brainiac (1958): Was created by Otto Binder and Al Plastino. Brainiac has a "12th-level intellect", allowing calculation abilities, enhanced memory and advanced understanding of mechanical engineering, bio-engineering, physics, and other theoretical and applied sciences, as well as extensive knowledge of various alien technologies. For comparison, the population of 20th century Earth as a whole constitutes a 6th-Level intelligence and the population of 31st century Earth as a whole is a 9th-Level intelligence. The character has created devices such as a force field belt and a shrinking ray capable of reducing cities. Brainiac's advanced mental powers have shown him capable of possessing others, absorbing information from other beings, transferring his consciousness,creating and manipulating computer systems, replicating multiple versions of himself, and exerting powers to traverse or control space and time. John Byrne's re-imagining of the character possessed telepathy and telekinesis that were further augmented by an implanted electrode head-piece.
Swamp thing (July 1971): Created by writer Len Wein and artist Berni Wrightson. The Swamp Thing character first appeared in House of Secrets #92 (June–July 1971), under the name Alex Olsen. The comic is set in the early 20th century, when Olsen, a scientist, is caught in a lab explosion caused by his co-worker, Damian Ridge, who intended to kill him to gain the hand of Olsen's wife Linda. Olsen is physically altered by chemicals and the forces within the swamp. He is transformed into a monstrous creature who kills Ridge before the latter can murder Linda, who has started to suspect Ridge of murdering Alex. Unable to make Linda realize his true identity, he returns to the swamp.
Man thing (May 1971): Created by writers Stan Lee, Roy Thomas, and Gerry Conway and artist Gray Morrow. Young biochemist Dr. Theodore "Ted" Sallis, a native of Omaha, Nebraska, is working in the Everglades as part of Dr. Wilma Calvin's Project: Gladiator team, which includes Dr. Barbara Morse and her fiancé Dr. Paul Allen. A Dr. Wendell is later cited as being on the staff after Dr. Calvin is shot.The group is attempting to recreate the "Super-Soldier Serum" that had created Captain America. Web of Spider-Man vol. 2, #6 revealed that Sallis at one point treated and worked alongside Dr. Curt Connors shortly after Connors' arm was amputated, driving the research that would eventually transform Connors into the Spider-Man foe the Lizard.
Superman (1938): Was created by writer Jerry Siegel and artist Joe Shuster. Superman's origin, relationships and abilities changed significantly during the character's publication, from what is considered the Golden Age of Comic Books through the Modern Age. The powers and villains were developed through the 1940s, with Superman developing the ability to fly, and costumed villains introduced from 1941. The character was shown as learning of the existence of Krypton in 1949. The concept itself had originally been established to the reader in 1939 in the Superman comic strip. The 1960s saw the introduction of a second Superman. DC had established a multiverse within the fictional universe its characters shared. This allowed characters published in the 1940s to exist alongside updated counterparts published in the 1960s. This was explained to the reader through the notion that the two groups of characters inhabited parallel Earths. The second Superman was introduced to explain to the reader Superman's membership in both the 1940s superhero team the Justice Society of America and the 1960s superhero team the Justice League of America.
Hyperion (1969): Was created by Roy Thomas and John Buscema. All versions of Hyperion possess superhuman strength, stamina, speed, and durability, and flight. Each also has greatly enhanced sensory perceptions, which extends to being able to perceive the entire electromagnetic spectrumand "atomic vision" - the equivalent of heat vision. The heroic Earth-712 version of Hyperion also possesses the ability to use cosmic energy to augment his life force granting him great longevity and regenerative abilities, courtesy of his Eternal heritage. The Earth-712 Hyperion's powers and vitality are diminished when he is exposed to argonite radiation. The Earth-712 Hyperion also has a college degree in journalism
Mr Fantastic (1961): Was created by Stan Lee and Jack Kirby. Born in Central City, California, Reed is the son of Evelyn and Nathaniel Richards. Nathaniel was a scientific genius, and Reed inherited a similar level of intellect and interests. A child prodigy with special aptitude in mathematics, physics, and mechanics, Reed Richards had enrolled in college by the time he was 14, attending such prestigious universities as the Massachusetts Institute of Technology, California Institute of Technology, Harvard University, Columbia University, and the fictional Empire State University. By the age of 20,he had several degrees in the sciences under his belt. It was at State University (not to be confused with Empire State University) that he met Benjamin J. Grimm. Reed had already begun designing a starship capable of traveling in hyperspace. Sharing his plans with his new roommate, Grimm jokingly volunteered to pilot the craft. When 19-year old Reed continued his education by attending Columbia University in Manhattan, he rented a room in a boarding house owned by the aunt of a young girl named Susan Storm. To his embarrassment, the girl, who was 13, instantly fell in love with him. Even though Reed had to move on, she continued to carry a torch for Richards. Also while at Columbia, he met a brilliant fellow student, Victor Von Doom. In Richards, Doom met the first person who could match him intellectually; regarding Richards as his ultimate rival, Doom became increasingly jealous of Richards. Determined to prove he was better, Doom conducted reckless experiments which eventually scarred his face and would lead him to become Doctor Doom.
Plastic man (1941): Created by writer-artist Jack Cole. Plastic Man was a crook named Patrick "Eel" O'Brian. Orphaned at age 10 and forced to live on the streets, he fell into a life of crime. As an adult, he became part of a burglary ring, specializing as a safecracker. During a late-night heist at the Crawford Chemical Works, he and his three fellow gang members were surprised by a night watchman. During the gang's escape, Eel was shot in the shoulder and doused with a large drum of unidentified chemical liquid. He escaped to the street only to discover that his gang had driven off without him. Fleeing on foot and suffering increasing disorientation from the gunshot wound and the exposure to the chemical, Eel eventually passed out on the foothills of a mountain near the city. He awoke to find himself in a bed in a mountain retreat, being tended to by a monk who had discovered him unconscious that morning. This monk, sensing a capacity for great good in O'Brian, turned away police officers who had trailed Eel to the monastery. This act of faith and kindness—combined with the realization that his gang had left him to be captured without a moment's hesitation—fanned Eel's longstanding dissatisfaction with his criminal life and his desire to reform.
Vision (1968): Created by Roy Thomas, Stan Lee and John Buscema. The robot Ultron is the creator of the Vision, a type of android he calls a "synthezoid", for use against Ultron's own creator, Dr. Hank Pym (Ant-Man/Giant Man/Goliath/Yellowjacket) and Pym's wife, Janet van Dyne (the Wasp) of the superhero team the Avengers. Ultron sends his new servant to lead the Avengers into a trap. The Wasp is the first to encounter the synthezoid, and describes it as a "vision" while trying to escape. Adopting the name, the Vision is convinced by the Avengers to turn against Ultron. After learning how Ultron created him, using the brain patterns of then-deceased Simon Williams (Wonder Man), the Vision becomes a member of the team. The team initially believes the Vision's body was created from that of the android original Human Torch. The Avengers later are told that the time lord Immortus used the power of the Forever Crystal to split the original Human Torch into two entities - one body remained the original Torch while Ultron rebuilt the other as the Vision. This was part of his plan to nurture a relationship for the Scarlet Witch that would prevent her from having any children, as her power level meant that any offspring she might have could threaten the cosmic beings of the Marvel Universe.
Martian manhunter (1955): Created by writer Joseph Samachson and artist Joe Certa. The Martian Manhunter (J'onn J'onzz) debuted in the back-up story "The Strange Experiment of Dr. Erdel" in Detective Comics #225 (Nov. 1955), written by Joseph Samachson and illustrated by Joe Certa. The character is a green-skinned extraterrestrial humanoid from the planet Mars, who is pulled to earth by an experimental teleportation beam (originally presented as an attempted communication device) constructed by Dr. Saul Erdel. The Martian tells Erdel where he is from, and is told that to send him back will require the Computer Brain's thinking plot to be changed. The shock of the encounter kills Dr. Erdel and leaves J'onn with no method of returning home. The character decides to fight crime while waiting for Martian technology to advance to a stage that will enable his rescue. To that end, he adopts the identity of John Jones, a detective in the fictional Middletown, U.S.A.
Hulk (1962): Was created by Stan Lee and Jack Kirby. During the experimental detonation of a gamma bomb, scientist Bruce Banner rushes to save teenager Rick Jones who has driven onto the testing field; Banner pushes Jones into a trench to save him, but is himself hit with the blast, absorbing massive amounts of gamma radiation. He awakens later in an infirmary, seeming relatively unscathed, but that night transforms into a lumbering grey form that breaks through the wall and escapes. A soldier in the ensuing search party dubs the otherwise unidentified creature a "hulk". The original incarnation of Banner transformed into the Hulk at sunset and reverted at sunrise. Banner was cured in The Incredible Hulk #4, but chose to restore Hulk's powers with Banner's intelligence. The gamma-ray machine needed to affect the transformation-induced side effects that made Banner temporarily sick and weak when returned to his normal state. In The Avengers #1 (September 1963), the Hulk became a founding member of the title's eponymous superhero team. However, by The Avengers #3, overuse of the gamma ray machine rendered the Hulk as an uncontrollable, rampaging monster, subject to spontaneous changing. In Tales to Astonish #59 (September 1964) the Hulk appeared as an antagonist for Giant-Man. The series established stress as the trigger for Banner turning into the Hulk and vice versa. It was during this time that the Hulk developed a more savage and childlike personality, shifting from the brutish figure who spoke in complete sentences and his memory, both long-term and short-term, was markedly impaired in his Hulk state. In Tales to Astonish #77 (March 1966), Banner's and the Hulk's dual identity became publicly known when Glenn Talbot, Banner's romantic rival for Betty Ross, witnessed his transformation, turning Banner into a wanted fugitive.
Solomon Grundy (1944): Was created by Alfred Bester and Paul Reinman. n the late 19th century, a wealthy merchant named Cyrus Gold is murdered and his body disposed of in Slaughter Swamp, near Gotham City. Fifty years later, the corpse is reanimated as a huge shambling figure (composed partly of the swamp matter that has accumulated around the body over the decades) with almost no memory of its past life. Gold murders two escaped criminals who are hiding out in the marsh and steals their clothes. He shows up in a hobo camp and, when asked about his name, one of the few things he can recall is that he was "born on a Monday". One of the men at the camp mentions the nursery rhyme character Solomon Grundy (who was born on a Monday), and Gold adopts the moniker. Strong, vicious, and nearly mindless, Solomon Grundy falls into a life of crime—or, perhaps returns to one as his scattered residual memories may indicate—attracting the attention of the Green Lantern, Alan Scott. Grundy proves to be a difficult opponent, unkillable (since he is already dead) and with an inherent resistance to Scott's powers (which cannot affect wood, a substance of which Grundy's reassembled body is now largely composed). He apparently kills Green Lantern, who gives off a green flash. Liking this flash, Grundy commits murders hoping to see the flash again. However the first fight ends when Grundy is hurled under a train by Green Lantern. Grundy is revived when a criminal scientist, known as the Professor, injects Grundy with concentrated chlorophyll.
Deadpool (1991): Created by artist Rob Liefeld and writer Fabian Nicieza. Deadpool's primary power is an accelerated healing factor, depicted by various writers at differing levels of efficiency. Artificially endowed by the Weapon X program, this enables him to regenerate any destroyed tissue at a super-human rate as well as making him immune to all known diseases. An unanticipated side effect was an acceleration of the cancerous tumors he was suffering from at the time, causing them to quickly spread across his entire body. Because of this, his healing factor supercharged his cancer, resulting in massive scar tissue causing his appearance to be severely deformed.Deadpool's brain cells are similarly affected, with dying brain cells being rejuvenated at a super accelerated rate. This allows Deadpool to recover from any head wounds, and it renders him nearly invulnerable to psychic and telepathic powers, as the altered or damaged brain cells quickly regenerate to their original state. It is also the cause of his psychosis and mental instability. It is sometimes implied that his healing factor merely bolstered and exacerbated an underlying mental issue, as a young Wade Wilson was shown as a withdrawn, disturbed young kid caught in his many daydreams, and when Deadpool at one point lost his healing factor, he did not regain his sanity. Deadpool's healing factor is strong enough that he has previously survived complete incineration and decapitation more than once. Although his head normally has to be reunited with his body to heal the wound, he was able to regrow his head after having it pulverized by the Hulk. Unlike Wolverine's natural healing factor, Deadpool's is mentally driven. Similar to Wolverine, his healing factor also affects his physical attributes by increasing them to superhuman levels. Though in earlier years he also had super-human strength, that detail has apparently been forgotten. Deadpool's body is highly resistant to most drugs and toxins. For example, it is extremely difficult for him to become intoxicated. He can be affected by certain drugs such as tranquilizers, if he is exposed to a large enough dosage. Deadpool's healing factor also slows the aging process. He is still alive 800 years in the future when the new X-Force encounters him.
Deathstroke (1980): Was created by Marv Wolfman and George Perez. Slade Wilson was sixteen years old when he first enlisted in the United States Army, having lied about his age. After serving a stint in Korea, he was later assigned to Camp Washington where he had been promoted to the rank of Major. In the early 1960s, he met Captain Adeline Kane who was tasked with training young soldiers in new fighting techniques in anticipation of brewing troubles taking place in Vietnam. Kane was amazed at how skilled Slade was and how quickly he adapted to modern conventions of warfare. She immediately fell in love with him, and realized that he was without a doubt the most able-bodied combatant she had ever encountered. She offered to privately train Slade in guerrilla warfare. In less than a year, Slade mastered every fighting form presented to him and was soon promoted to the rank of Lieutenant Colonel. Six months later, Adeline and he were married and she became pregnant with their first child. The war in Vietnam began to escalate and Slade was shipped overseas. In the war, his unit massacred a village, an event which sickened him. He was also rescued by SAS member Wintergreen, to whom he would later return the favor. Chosen for a secret experiment, the Army imbued him with enhanced physical powers in an attempt to create meta-human super-soldiers for the U.S. military. Deathstroke became a mercenary soon after the experiment when he defied orders and rescued his friend Wintergreen sent on a suicide mission by a commanding officer with a grudge. However, Slade kept this career secret from his family, even though his wife was an expert military combat instructor.A criminal named the Jackal took his younger son Joseph Wilson hostage to force Slade to divulge the name of a client who had hired him as an assassin. Slade refused, claiming it was against his personal honor code. He attacked and killed the kidnappers at the rendezvous. Unfortunately, Joseph's throat was slashed by one of the criminals before Slade could prevent it, destroying Joseph's vocal cords and rendering him mute.
