[3] Among the many characters Pérez created or co-created are Cyborg, Raven, Starfire, Deathstroke, and the Nightwing identity of Dick Grayson.

They married in October 1954 and subsequently moved to New York, where Jorge worked in the meat packing industry while Luz was a homemaker.

Pérez drew the first part of writer Jim Shooter's "The Korvac Saga", which featured nearly every Avenger who had joined the team up to that point.

[15][16] Shooter and Pérez introduced the character of Henry Peter Gyrich, the Avengers' liaison to the United States National Security Council in the second chapter of that same storyline.

[19] While Pérez's stint on the JLA was popular with fans, he received greater attention for his work on The New Teen Titans,[20] which was launched in a special preview in DC Comics Presents #26 (October 1980).

[21] This incarnation of the Titans was intended to be DC's answer to Marvel's increasingly popular X-Men comic, and it became highly successful.

[25] Moreover, Pérez's facility with layouts, details, and faces improved enormously during his four years on the book, making him one of the most popular artists in comics[26][27] as evidenced by the numerous industry awards he would receive during this time.

Pérez took a leave of absence from The New Teen Titans in 1984[28] to focus on his next project with Marv Wolfman, DC's 1985 50th-anniversary event, Crisis on Infinite Earths.

Writer Greg Potter spent several months working with editor Janice Race on new concepts for the character, before being joined by Pérez.

[34][35] Inspired by John Byrne and Frank Miller's work on refashioning Superman and Batman, Pérez came in as the plotter and penciler of the series,[36] which tied the character more closely to the Greek gods[37] and jettisoned many other elements of her history.

[46] These new designs for the villain were featured as part of the licensed action figure toyline the Super Powers Collection and remain in use in today's DC Comics continuity.

His work duties on Action Comics would change from writer/penciller, to co-writer/breakdowns, to providing breakdowns, with writer Roger Stern scripting stories and artists Brett Breeding and Kerry Gammill provided finishing art, while Pérez drew all covers during his run on the title, with the exception for issue #646 with interior pencils by Keith Giffen.

In the double-size anniversary issue #650 in February 1990, Pérez penciled and inked an eight page flashback story depicting Superman's first post-Crisis encounter with the Justice League of America.

Also in 1991, Pérez signed on to pencil the six-issue limited series Infinity Gauntlet for Marvel Comics, which was written by Jim Starlin.

[48] However, due to the turbulence happening concurrently with War of the Gods, this was a very stressful personal period for Pérez, and he was not able to finish penciling the entire run of Infinity Gauntlet, leaving the project part way through issue #4.

[49] Because of the debacles over War of the Gods and The Infinity Gauntlet, Pérez began to gain a reputation as a creator who could not finish projects as planned.

Pérez finally returned to a major ongoing title for the third series of The Avengers, written by Kurt Busiek,[55] where he remained for nearly three years, again receiving critical and fan acclaim for his polished and dynamic art.

[58] In 1997, Pérez began writing and illustrating Crimson Plague, a creator-owned science fiction story about an alien with ultra-toxic blood, with the first issue published by Event Comics.

[61] His main project for the company was penciling Solus,[62] which was intended to be an ongoing series, but was cancelled after eight issues due to CrossGen's bankruptcy.

He worked with Marv Wolfman on a direct-to-DVD movie adaptation of the "Judas Contract" story arc from Teen Titans, scheduled for 2017.

The New Teen Titans: Games hardcover graphic novel[68] was published the same month reuniting the creative team of Wolfman and Pérez.

[69] He was the inker of the new Green Arrow series, also launched in the same timeframe, over artist Dan Jurgens' pencils, reuniting the mid-1990s Teen Titans art team.

This included inconsistent reasons given for rewrites of his material, the inability of editors to explain to him basic aspects of the New 52 Superman's status quo (such as whether his adoptive parents were still alive), and restrictions imposed by having to be consistent with Action Comics, which was set five years earlier than Superman, a situation complicated by Action writer Grant Morrison having not been forthcoming about their plans.

It is a science fiction miniseries dedicated to a group of women with extraordinary powers, who fight against evil across time and space.

[76] In May 2017, he was admitted to a hospital with chest pains due to a heart attack while traveling to a convention, and had a coronary stent fitted.

[78][79][80] In early 2022, both DC and Marvel included tributes to him and his work in their comics,[81][82] and jointly approved a limited-run reprint of the 2003 JLA/Avengers story he illustrated (long tied up by disagreements between the rival publishers), as a benefit for The Hero Initiative.

Pérez won a 1979 Eagle Award (with Jim Shooter, Sal Buscema, and David Wenzel) for Best Continued Story for his work on The Avengers #167–168 and 170–177.

[89] His work (with Marv Wolfman and Romeo Tanghal), earned The New Teen Titans #50 a nomination for the 1985 Jack Kirby Award for Best Single Issue.
