Hey there. I was just wondering: In the comics, Robotnik Mach Two and Mecha-Snively are blown up by nuclear bombs sent by Station Square. I can understand Robotnik surviving because he can download into another body, but what happens to Snively? Is he gone now? Also, I been trying to find the story for "Knuckles: 20 Years Later." Do you have any clue where I could find it?
1) Wait 'til #117 & #118 which deals with both of them.
2) I'm not sure what you mean by "story." If you mean what comic it was in, it was never published and as things currently stand won't be despite it being mentioned and partially referenced in Knuckles #25 and Super Special #7. If you mean the spoilery info released over the past 4 years, check this site.
