Marvel Comics

The third Fantastic Four omnibus covers the final period of the Lee/Kirby collaboration — the run toward Kirby's departure to DC, featuring the introduction of the Him/Warlock concept, Crystal's full integration into the team after Sue Storm's pregnancy, and the complete Kree/Skrull setup that Thomas would develop in Avengers. These late Kirby issues show a creator pushing against the creative constraints of the Marvel system before leaving for DC and the New Gods concept that would be his ultimate artistic statement.
