Silvaze

Silvaze is the het ship between Silver the Hedgehog and Blaze the Cat from the Sonic the Hedgehog fandom.

Canon
Both Silver and Blaze are best friends, who they are described to have a brother-sister relationship in Sonic the Hedgehog (2006) exclusively. Silver is also emotionally dependent upon Blaze; he becomes very insecure when alone, and it is usually Blaze who helps Silver back on his feet. Before she vanishes from their world at the end of Silver's story, Blaze reveals that she always liked Silver's naivete, leaving Silver deeply saddened after he is forced to seal her in another dimension.

However, after the defeat of Solaris, the timeline was altered and it appears that Silver's encounter with Blaze was erased, leaving them with no personal relation or friendly knowledge of each other. In Sonic Colors (DS version only) shows Silver and Blaze meeting each other after the timeline changed.

Fanon
Despite they doesn't have any canon proof that can be considered "romantic" by fans about their relationship after the timeline was altered, Silvaze is one of the most popular ships in the Sonic fandom.

Trivia

 * In Archie's Sonic Universe Issue 58's Off Panel, Marine seems to have written a Silvaze fanfiction, and however Blaze apparently disliked the story and burned Marine's manuscript. This is a possible allusion of writers' consciousness to the shipping fanbase.
