Tailsco

Tailsco is the het ship between Tails and Coco from the Sonic the Hedgehog and Crash Bandicoot fandoms.

Canon
As there has never been an official Sonic the Hedgehog and Crash Bandicoot crossover, the two have never met.

However, both characters share a lot of similarities that often make them seen as each other’s equal. Primarily, Tails and Coco share similar introductions in their respective franchises in that they first appeared in the second main series entry. Following their debut's, they are often treated as the sidekick character to Sonic and Crash, even if the actual relationships differ somewhat. That said, the loyalty and friendship they have to their heroes is unbreakable.

Tails and Coco are also both described as "kid geniuses" and have displayed an aptitude for technology and machinery, including being able to pilot and control multiple vehicles. They have also been shown to create inventions and hack equipment that have proved vital in helping their heroes save the day.

Fanon
Despite the similarities between the characters and its general acceptance, the actual popularity of this ship is questionable. While Crash Bandicoot and Sonic the Hedgehog fan content is relatively popular, there is very little material about Tails and Coco exclusively – let alone as a couple. It is unclear why this is the case, although it could simply be that the other Tails and Coco pairings within their respective franchises are more popular.

Those wishing to find fanart tend to struggle, as much of it was uploaded without any search tags. One of the most notable fan-artists for the pairing initially was bluefirerocker, who during the early 2010's drew a lot of artwork of the two together. However, they haven't uploaded any further fanart of the pairing since 2014, and as of 2021 their account has been disabled. At around the same time, an unrelated user by the name of started to upload fanart of the pairing themselves.

A common theme in most fanfictions for Tails and Coco is for the pair to bond over technology and/or science, as it's an area that both are known to be experienced and knowledgeable in.
