Tailaze

Tailaze is the het ship between Tails and Blaze from the Sonic the Hedgehog fandom.

Games
Blaze makes her debut in Sonic Rush. After Blaze and Sonic defeat their respective zone bosses, they, along with Tails and Cream, meet each other on a small island. The cat introduces herself, and the fox asks about the spreading of the space-time continuum tear. Blaze replies that it is her problem and runs off. Later, Tails gives the news that Cream was kidnapped by Dr. Eggman and the cat is to go to Point W alone.

In Sonic the Hedgehog, both collected Chaos Emeralds to revive Sonic. They are seen watching the hedgehogs depart to defeat Solaris. As a result of the Elise putting out the Flame of Hope, all of the game's events have been erased, including interactions between the major characters, including that of Tails and Blaze.

Both appear in Sonic's birthday party in Sonic Generations and were sucked into a space-time portal. The hedgehog freed them after collecting all five stars in each of their respective zones. Blaze and Tails are later seen cheering on the Sonics and returning to the party along with the other main characters.

In the Mario & Sonic series, both are competitors and there are costumes in their likeliness for your Mii. The Super Smash Bros. series has them as collectible items.

Fanon
The ship is somewhat popular, though not as popular as ships such as Tails with Cream and Blaze with Silver or Sonic. The ship generally has a more respectful fandom than the popular Sonic pairings.
