Cross Generation Entertainment or CrossGen was an American comic book publisher and entertainment company that operated from 1998 to 2004. The company's assets were acquired by The Walt Disney Company in 2004, and designated to Disney Publishing Worldwide. In July 2010, Disney re-established the brand through Marvel Comics, who announced plans to revive CrossGen titles.

CrossGen Comics, Inc., was founded in 1998, in Tampa, Florida, by entrepreneur Mark Alessi.

In 1999, the company acquired the Orlando-based multi-genre fan convention MegaCon, from founder James Breitbiel.  Breitbiel became CrossGen's Marketing and Distribution Director.

In January 2000, CrossGen Comics, Inc. debuted with CrossGenesis, a sneak-peek at the CrossGen universe. It provided an outline of the universe, worlds, and characters of CrossGen's flagship titles that would be released six months later. Gina M. Villa, head of creative departments, and Mark Alessi wrote a history of the Sigilverse before any comics were written. The head creative team consisted of Barbara Kesel, Mark Waid and Ron Marz. Unlike other comics publishers such as DC Comics and Marvel Comics, which rely mainly on freelance writers and artists, most of CrossGen's talent were salaried employees of the company and worked out of its headquarters in Oldsmar, Florida. Later creators such as J.M. DeMatteis worked freelance, with CrossGen publishing finished properties. The company's publications covered a variety of genres with characters inhabiting a single shared universe.

In July 2004, Disney Publishing was interested in licensing CrossGen content but, upon discovering the company's bankruptcy, began seeking to acquire its assets instead. Founder Alessi loaned the company $75,000, but was unable to prevent the company's takeover. On November 15, Disney purchased CrossGen's assets for $1 million with plans to publish four prose hardcover novels based on writer J.M. DeMatteis and artist Mike Ploog's Abadazad.

In July 2010, Marvel Comics' editor-in-chief Joe Quesada announced at the San Diego Comic-Con that Marvel (also a Disney-owned company) would revive a number of CrossGen titles.

Marvel began to publish Ruse and Sigil in March 2011 as four-issue miniseries. Both completed their run, and a third Crossgen title, Mystic, premiered in August 2011. Two more books, Route 666 and Kiss Kiss Bang Bang, were announced during Fan Expo Canada in late August, and were set to start in February 2012, but were never published due to low interest in the previously released series.

In August 2022, Marvel Comics announced CrossGen Tales #1, a trade paperback collection that contains the reprinted original first issues of Mystic, Sigil, Ruse, and Soujourn. This would be the first time that CrossGen titles would be available in a digital format.

With art by George Perez and Tom Ryder.  George Pérez (June 9, 1954 – May 6, 2022) was an American comic book artist and writer, who worked primarily as a penciller. He came to prominence in the 1970s penciling The Avengers for Marvel Comics, and returned to the franchise in the 1990s. In the 1980s he penciled The New Teen Titans, which became one of DC Comics' top-selling series. He penciled DC's landmark limited series Crisis on Infinite Earths, followed by relaunching Wonder Woman as both writer and penciller for the rebooted series. In the meantime, he worked on other comics published by Marvel, DC, and other companies into the 2010s. He was known for his detailed and realistic rendering, and his facility with complex crowd scenes.

In October 2013, Pérez revealed that he would soon undergo laser and injection surgeries to address hemorrhaging in his left eye that had effectively made him blind in that eye. By the following June, the procedures were not yet completed, but his condition had improved to the point that he was able to resume his work. 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. By January 2019, Perez was dealing with multiple health issues, including diabetes and problems with his vision and his heart.

In December 2021, he revealed that after undergoing surgery for a blockage in his liver, he had been diagnosed with inoperable pancreatic cancer. Given a prognosis of 6 to 12 months, he chose not to pursue treatment. In early 2022, both DC and Marvel included tributes to him and his work in their comics, 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.
