Mephilver

Mephilver is the slash ship between Silver the Hedgehog and Mephiles the Dark in 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.

Fanon
This ship typically includes the hedgehog form of Mephiles as slash ships between hedgehogs are popular. Mephilver is typically shipped alongside Sonadow.
