George Pérez began his comics career in 1973, assisting Rich Buckler on a back-up story in Astonishing Tales. A year later, he was assigned by Marvel to do some stories for the 'Deadly Hands of Kung-Fu' and 'Creatures on the Loose' titles. He then became a regular artist on such comics as 'Fantastic Four', 'The Inhumans' and 'The Avengers'. He eventually left Marvel and joined DC, where he created his best remembered work, 'The New Teen Titans' with Marv Wolfman. He drew this title for four years, after which he took on the limited series 'Crisis on Infinite Earths', again with Wolfman. He then drew the encyclopedic 'History of the DC Universe' and had a run on 'Wonder Woman', a comic for which he also wrote scripts.
He was present at Marvel again with the limited series 'The Infinity Gauntlet', 'The Incredible Hulk: Future Imperfect' and 'Sachs & Violens'. He inked Gil Kane's comic adaptation of 'Jurassic Park' for Topps, and joined Malibu Comics to do the crossover mini-series 'Break-Thru' as well as 'UltraForce'. He also did 'I-Bots' at Tekno-Comix and returned to DC as the inker of Dan Jurgens' rendition of 'The Teen Titans'. Perez returned to 'The Avengers' in 1997. In addition, he began his own creator-owned mini-series 'Crimson Plague' for Event Comics. At CrossGen, he took on 'Solus' and 'JLA/Avengers'.
