"Days of Future Present" is a storyline published by Marvel Comics, appearing in the 1990 annuals of Fantastic Four, X-Factor, New Mutants and The Uncanny X-Men.

Centered on the appearance of an adult version of the powerful mutant Franklin Richards, it is a sequel to the popular "Days of Future Past" story arc from The Uncanny X-Men #141–142 (January–February 1981).

The storyline unites the Fantastic Four, X-Factor, the New Mutants, and the remnants of a then-disbanded X-Men against a common foe from a dystopian alternate future.

Cyclops' baby son Nathan Christopher Charles Summers and the full-grown mutant antihero Cable are depicted in this story as two separate individuals, although they are subsequently revealed to be one and the same.

In doing so, his energy signature is sensed by Rachel Summers (who is in Great Britain with the team Excalibur), X-Men members Forge and Banshee (also in New York City), and a futuristic mutant-hunter named Ahab.

After defeating a group of miniature Sentinel droids, the Fantastic Four (joined by Forge and Banshee) search for the adult Franklin at the home of the Power family.

Having noticed the Ship's disappearance, Forge, Banshee and the Fantastic Four arrive, and team up with X-Factor (Cyclops, Jean Grey, Archangel, Iceman, and the Beast) to locate the adult Franklin.

When Reed & Sue Richards bring up the problems with Ahab, baby Nathan, and X-Factor's Ship, adult Franklin induces in them a euphoric, docile state of mind, allowing him to leave.

Ahab transforms Cyclops and the Invisible Woman into Hounds, and uses them to locate and capture Rachel, the adult Franklin and baby Nathan.

Meanwhile, Storm briefs the collective heroes on Rachel's dystopian future, where the Sentinels have conquered North America and almost all super-powered beings have been slain or imprisoned in internment camps.

The young Franklin regains consciousness with his latent powers intact, and Rachel uses the Phoenix Force to genetically restore Cyclops and the Invisible Woman to their natural forms.

X-Men Annual #14 contains a back-up story entitled "The Fundamental Things", written by Chris Claremont and pencilled by Mark Heikel.

The story is set in Madripoor, where Wolverine (accompanied by Psylocke) tells his new teenage companion Jubilee about Charles Xavier and the X-Men.
