Fantastic Four Annual 23, cover date of July 1990, was the first part of the Days of Future Present arc that continued in X-Factor Annual 5, then the New Mutants Annual 6, and concluded in the X-Men Annual 14. In the "When Franklin Comes Marchin' Home" segment, Ahab was introduced, created by Walter Simonson, Bob Harras, and Jackson Guice. The Fantastic Four were shocked when their old Baxter Building suddenly reappeared in New York and was even manned by their old door man O'Hoolihan. They then encountered the "original" (younger versions) of the Fantastic Four and adult Franklin. The Rachel Summers version of Pheonix was disrupted by Franklin's appearance as they both came from the same timeline. Ahab, from that timeline, noticed Franklin's journey and opened a time portal to bring him back. Roxanne Arnold was introduced in the "Cast in Fire, Carved in Stone" segment. She was created by James Brock and Mark McKenna. Volcana (Marsha Rosenberg) was secretly observed by Doctor Doom, who believed she had been given extra cosmic powers by Owen Reece. His suspicions seemed to be confirmed when she healed a hospital full of people (including Roxanne Arnold) and created a hard magma shell when attacked by Moonstone (Karla Sofen). In the "Beyond and Back" after a cosmic cube breaks, the Beyonder returned, but now in a female form that it dubbed Kosmos (first appearance as Kosmos). Kosmos was met by Kubik, who gave her a crash course on the universe, including the Pheonix Force, the Watchers, Mangog, Overmind, Uni-Mind, High Evolutionary, the Stranger, Eon, the Celestials, Vishanti, Mephisto, D'Spayre, Dweller-in-Darkness, Shuma-Gorath, Thanos, Satannish, Chthon, Eternity, Death, Master Order, Lord Chaos, In-Betweener, Living Tribunal, and Galactus.
