Myself 123 wrote: Silver might exist in an alternate future as well as changes made in the past didn't seem to save his era from Iblis. As Silver was partly inspired by Future Trunks from DBZ, it may be that time travel works similarly in Sonic '06 as it does DBZ, but that is speculation. As neat as that would be (being a Dragon Ball and Future Trunks fan myself), that doesn't really make sense, because in Rivals and Colors DS, Silver's future had changed, and there is no Iblis.

Unless you're suggesting there exists multiple Silvers each with their own timeline?
