Bruce Walter Timm (born February 5, 1961) is an American artist, character designer, animator, writer, producer and voice actor. He is best known for his contributions building the modern DC Comics animated franchise, most notably Batman: The Animated Series (1992–1995) and the subsequent DC Animated Universe, for which Timm made most of the character designs. Timm and Paul Dini co-created the characters Harley Quinn and Terry McGinnis.

He began his animation career as a layout artist for animation studios such as Filmation, Bakshi Productions, and Don Bluth Productions, before joining Warner Bros. in 1989. In addition to Batman: The Animated Series, Timm was a producer and writer for other DCAU series such as Superman: The Animated Series (1996–2000), The New Batman Adventures (1997–1999), Batman Beyond (1999–2001), Justice League (2001–2004), and Justice League Unlimited (2004–2006). He also co-created Freakazoid! (1995–1997) with Dini and developed Green Lantern: The Animated Series (2012–2013). Following the conclusion of the DCAU, Timm went on to produce several DC animated films.

Outside of animation, Timm has also drawn several comic books. Timm and Dini collaborated on The Batman Adventures: Mad Love, which won the Eisner Award for Best Single Story in 1994. Timm has also released two art books showcasing his erotic drawings of women, Naughty and Nice: The Good Girl Art of Bruce Timm and The Big Tease: A Naughty and Nice Collection.

Iron Man is a superhero appearing in comic books published by Marvel Comics. The character was co-created by writer and editor Stan Lee, developed by scripter Larry Lieber, and designed by artists Don Heck and Jack Kirby. The character made his first appearance in Tales of Suspense #39 (cover dated March 1963), and received his own title in Iron Man #1 (May 1968). Also in 1963, the character founded the Avengers alongside Thor, Ant-Man, Wasp and the Hulk.

A wealthy American business magnate, playboy, philanthropist, inventor and ingenious scientist, Anthony Edward Stark suffers a severe chest injury during a kidnapping. When his captors attempt to force him to build a weapon of mass destruction, he instead creates a mechanized suit of armor to save his life and escape captivity. Later, Stark develops his suit, adding 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. Although at first concealing his true identity, Stark eventually publicly reveals himself to be Iron Man.

Initially, Iron Man was a vehicle for Stan Lee to explore Cold War themes, particularly the role of American technology and industry in the fight against communism. Subsequent re-imaginings of Iron Man have transitioned from Cold War motifs to contemporary matters of the time.
