I haven't share the list yet, but here are some of the main characters, also there are mayor changes in the timeline of this "possible future":
Alex and Sophie Petrelli, the twin children of Peter Petrelli and Emma Coolidge. In this world Peter recovered his original power after inyecting himself with the formula, so the kids have both Synesthesia and Empathic Mimicry. As I said, they also have a power of their own, Alex developed the power of his great-grandfather, Seismic Burst. Sophie however got the power of Elemental Manipulation (A nod to Malina).
Noah Gray, the son of Gabriel Gray, a.k.a. Sylar, and Elle Bishop. In this world Gabriel didn't kill Elle or Bob, but he ended up dying anyways. Thanks to his father he was able to learn to control the "hunger" that comes with his Intuitive Aptitude. He also possesses his mother's electrokinesis, plus his own ability which is Ergokinesis, the ability to control energy itself.
Martin Nakamura, the son of Hiro Nakamura and Charlie Andrews. This couple finally got their happy ending and had this kid, who was born with the powers of Eidetic Memory and Space-Time Manipulation. After sometime he discovered his ability to mimic the powers of others after touching them, similar to Peter after Volume 3.
I'll send more info about others later.
Cool! You could make some posts and a hashtag about it so other people can follow ^.^
