Lost, Not Gone - A Sonic Fan Fiction Long Overdue

As any good sonic fan/player/viewer should know, the Sonic series has dished out quite a few very memorable side characters; however, some of these only show up for certain arcs, and as soon as that arc is over, are written out of Sonic lore. After beginning to re-watch the Sonic X series, I realized that three particular characters are, at least to me, not solidly written out. These characters either disappeared, shut down, or were out of view when what we assumed was their death occurred. I am speaking of the three Sonic X side characters Shadow, the Hedgehog; E-102 Gamma; and Emerl. This story does not include the Metarex Arc.

In this, I am going to do my own interpretation of the continuation of their stories. As I continue to re-watch the series, I may add more to this list. Don't take this as one of those, "But they were alive and everyone was happy to see them" fan fictions. I am writing this with the most realistic outcome of their continued stories that I can. All characters portrayed belong in full rights to SEGA. Though the stories written here are my own, the original lore they are based off of, as well as Sonic X, Sonic Adventure, Sonic Adventure 2, and Sonic Battle all belong in turn to SEGA.
