Fantastic Four Epic Collection #20

When a future version of Franklin Richards suddenly appears in the present, his arrival throws the current Fantastic Four into disarray. With memories of a different past, he moves to correct what he sees as broken — but his well-intentioned changes only deepen the mystery of who he truly is and what he’s trying to fix.

In "Beyond and Back," a newly awakened cosmic entity named Kosmos emerges from the fractured remnants of the Cosmic Cube, forged from the merged essence of the Beyonder and Molecular Man. Guided by Kubik—another evolved being born from a cosmic cube—she begins a journey through the vastness of the universe, where she's introduced to its wonders and mysteries by her enigmatic mentor.

In "The Once and Future Mutant," adult Franklin Richards returns to Xavier's School, rebuilding it with eerie precision—complete with the New Mutants—only to be met by the arrival of Banshee, the Invisible Woman, Mr. Fantastic, and young Franklin. When the enigmatic Ahab strikes, the two versions of Franklin must face off in a clash that blurs time, memory, and identity.

In "Act of Faith," the Fantastic Four join forces with a united mutant team to confront the dangerous machinations of Ahab and a desperate Franklin Richards from the future, whose vision of the past threatens to unravel reality. As timelines collide, Rachel confronts her mother, and the stakes rise when Franklin's desperate attempt to rewrite history alters existence itself.
