It was published by Sergio Bonelli Editore from April 1999 to July 2004, for a total of 64 issues, and then by Star Comics, which restarted it from number 0.
Jonathan Steele was created and respectively written and primarily illustrated by Federico Memola and Teresa Marzia.
Many other Italian artists have drawn the two monthly series, while the graphic novels are all illustrated by Joachim Tilloca.
The series' protagonist is Jonathan Steele, a detective who lives in 2020, in a world in which suddenly numerous people had turned into mutants and acquired magical powers.
Jonathan is now an international thief who has left (perhaps) his old work to collaborate with the Enchantment Agency, run by the powerful mage Jasmine (whose appearance is inspired by the Canadian model Yasmeen Ghauri) and the half-fairy Myriam.
