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. The Nintendo DS version of Sonic Colors shows Silver and Blaze meeting each other after the timeline changed. In the console version of Sonic Generations, the two can be seen talking to each other at Sonic's birthday party at the end of the game.
Silver and Blaze are sometimes shown together in spin-off games. In the Nintendo 3DS version of Mario & Sonic at the Olympic Winter Games, Silver and Blaze join Sonic's team together rather than individually. They also have unique victory poses in Mario & Sonic at the Sochi 2014 Olympic Winter Games and Mario & Sonic at the Rio 2016 Olympic Games. The two are members of Team Vector in Team Sonic Racing.
Despite losing their friendship and familiarity entirely with the end of Sonic 06, Silvaze is one of the most popular ships in the Sonic fandom.
On AO3, Silvaze is the most written ship for Blaze and the second most written for Silver, behind Shadow/Silver. However, it should be noted that AO3 cannot be used to determine total popularity, as the Sonic fandom has a more notable presence on other websites such as DeviantArt.

- 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.
