Mephilver

Mephilver is the slash ship between Mephiles the Dark and Silver the Hedgehog from the Sonic the Hedgehog fandom.

Canon
In Sonic the Hedgehog (2006), Mephiles tricked Silver into being his ally. Mephiles claimed that Sonic was the reason everything was in ruins and sent Silver to the past to kill Sonic. Eventually, Silver found out that Mephiles was in fact lying the whole time and instead wanted to cause even more destruction.

As the timeline was altered, Mephiles never existed, meaning Silver never met him. Despite this, Mephiles later returned in Sonic Runners as a Future type character alongside ESP Silver.

Fanon
This ship typically includes the hedgehog form of Mephiles. Mephilver is one of the most popular hedgehog slash ships and it is typically shipped alongside Sonadow.
