Back in the day Gary really struggled with how to introduce the "new" Sinister Six and went through several ideas. I remember he asked for my help on it once, but I didn’t like some of the ideas presented and couldn’t really think of a good way to get them to work. Years passed by and I made a "filler" story for him as a joke and shortly afterwards he died. And the story went completely forgotten.
And then I rediscovered it right after filling in the gap myself. Welp, it can still be salvaged! Presenting Encore Part 1! This story deals with some of Gary’s old ideas for an S6 revival that just didn’t see the light of day.
Continuity-wise the story takes place shortly after Ice VS Red and at the end of Series 4.
