Manamy

Manamy is the het ship between Manic the Hedgehog and Amy Rose from the Sonic the Hedgehog fandom.

Canon
The two have never met in canon as Manic only appears in Sonic Underground (and briefly in the Underground zone in Pre-Super Genesis Wave Archie Comics), while Amy is absent from the series.

As it is currently demanded by SEGA that Sonic game characters shouldn't have biological relatives (excluding the ones already introduced in the games), it is unlikely that Manic will ever appear in any official Sonic material again, meaning Amy and Manic will most likely never meet.

Fanon
The pairing has support, although it is notably less popular than many ships for Amy such as Sonamy, Shadamy or Silvamy. It is still a fairly popular ship with some fanart, and is one of the most popular ships for Manic along with Manina.
