Fantastic 4 Cracking Group — Italy, founded 1983

F4CG's sixty-third numbered intro, ranking 118th overall — a late-era production from 1997 with a full creative team. CSDb release 60018 credits Devil with the code, Zyron with the music, and Draz with both graphics and charset. Total Chaos is credited with the original idea, and Jucke assisted — notably by providing a scanned leaf from a plant named Bengt that grew in his kitchen window, which Draz then converted to C64 graphics. Total Chaos confirmed authorship on intros.c64.org, noting the intro belonged to him rather than Devil in the conceptual sense. F4CG was founded in Italy in 1983 by Ricky and is documented on CSDb with over 1,600 releases. By 1997, the group had transitioned from its cracking roots into broader scene activity. The collaboration between multiple contributors — across coding, music, graphics, and concept — reflects F4CG's mature organisational structure during their later period.
