Tailamy

Tailamy is the het ship between Tails and Amy from the Sonic the Hedgehog fandom.

Canon
In most canons where the two appear, Tails and Amy are shown as friends.

Games
The first game which both appear is in Sonic the Hedgehog's Gameworld, where they can be chosen by the player(s), along with Sonic, and compete against Dr. Robotnik for points and Chaos Emeralds. Tails and Amy are competitors in the later Classic-era games Sonic Drift, Sonic Drift 2, Sonic R, and Sonic the Fighters.

In Sonic Adventure, Amy is aged up and was given new attire.

Fanon
This pairing has some following. It is overshadowed by more popular ships like Tails with Cream or Cosmo, and Sonamy.

A DeviantArtist by the name of HopelessRomantic721 has been making a TailsAmy comic series since 2013. It is currently on hiatus after 26 pages of the second chapter were posted.
