Shadaze

Shadaze is the het ship between Shadow the Hedgehog and Blaze the Cat from the Sonic the Hedgehog fandom.

Canon
Shadow and Blaze mostly interacted in the Pre-Super Genesis Wave Sonic Universe comics. They first met when Shadow was fighting Metal Sonic and ended up in the Solution Dimension. Shadow almost drowned but was rescued by Blaze and Marine the Raccoon.

Shadow and Blaze met again when they were looking for the Solution Emeralds. While they were against each other at first, they eventually teamed up. At one point, Blaze was hurt and Amy ordered Shadow to carry her.

In the games, no notable interactions happened between the two but they met in a few games, including Sonic Generations.

Fanon
Shadaze gained popularity when the pair interacted in Sonic Universe, although it already had prior support. However, it is not as popular as rival ships such as Shadouge or Silvaze.

Shadow and Blaze have similar personality traits, as both are serious, quiet and rarely spend time in the company of others, although Blaze is friendlier than Shadow.

Trivia

 * Blaze was originally designed to look more similar to Shadow, although the design might have simply been a silhouette.
