Iron Man

Iron Man (Tony Stark) is a fictional superhero appearing in American comic books published by Marvel Comics, as well as its associated media. The character was created by writer and editor Stan Lee, developed by scripter Larry Lieber, and designed by artists Don Heck and Jack Kirby. He made his first appearance in Tales of Suspense #39 (cover dated March 1963).

An American billionaire playboy, business magnate, and ingenious engineer, Tony Stark suffers a severe chest injury during a kidnapping in which his captors attempt to force him to build a weapon of mass destruction. He instead creates a powered suit of armor to save his life and escape captivity. Later, Stark augments his suit with weapons and other technological devices he designed through his company, Stark Industries. He uses the suit and successive versions to protect the world as Iron Man, while at first concealing his true identity. Initially, Iron Man was a vehicle for Stan Lee to explore Cold War themes, particularly the role of American technology and business in the fight against communism. Subsequent re-imaginings of Iron Man have transitioned from Cold War themes to contemporary concerns, such as corporate crime and terrorism.

Penguin (comics)

The Penguin, real name Oswald Chesterfield Cobblepot, is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. Artist Bob Kane and writer Bill Finger introduced the character in Detective Comics #58 (December 1941). The Penguin is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.

The Penguin is depicted as being short and portly, and he is known for his love of birds and his specialized high-tech umbrellas. A mobster and thief, he fancies himself as being a "gentleman of crime;" his nightclub business provides a cover for criminal activity, which Batman sometimes uses as a source of criminal underworld information. According to Kane, the character was inspired from the then advertising mascot of Kool cigarettes – a penguin with a top hat and cane. Finger thought the image of high-society gentlemen in tuxedos was reminiscent of emperor penguins.

Batman

Batman is a fictional superhero appearing in American comic books published by DC Comics. The character was created by artist Bob Kane and writer Bill Finger, and first appeared in Detective Comics #27 (May 1939). Originally named "the Bat-Man", the character is also referred to by such epithets as the "Caped Crusader", the "Dark Knight", and the "World's Greatest Detective".

Batman's secret identity is Bruce Wayne, an American billionaire, playboy, philanthropist, and owner of Wayne Enterprises. After witnessing the murder of his parents as a child, he swore revenge on criminals, an oath tempered by a sense of justice. Wayne trains himself both physically and intellectually and crafts a bat-inspired persona to fight crime. Batman operates in the fictional Gotham City, with assistance from various supporting characters, including his butler Alfred, police commissioner Jim Gordon, and vigilante allies such as Robin. Unlike most superheroes, Batman does not possess any superpowers; rather, he relies on his genius intellect, physical prowess, martial arts abilities, detective skills, science and technology, vast wealth, provocation of fear and intimidation, and an indomitable will. A large assortment of villains make up Batman's rogues gallery, including his archenemy the Joker.

Mr. Freeze

Mr. Freeze, real name Victor Fries, is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman.

Mr. Freeze is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.

Freeze is a scientist who must wear a cryogenic suit in order to survive, and bases his crimes around a "cold" or "ice" theme, complete with a "freeze gun" that freezes its targets solid. In the most common variation of his origin story, he is a former cryogenics expert who suffered an industrial accident while attempting to cure his terminally ill wife Nora Fries.

Mr. Freeze was played by George Sanders, Otto Preminger and Eli Wallach in the original Batman television series and by Arnold Schwarzenegger in the 1997 film Batman & Robin, was voiced by Michael Ansara in Batman: The Animated Series and by Clancy Brown in The Batman, and has been voiced by Maurice LaMarche in the Batman: Arkham video game franchise.
