You mean an OC, few take them seriously anymore as most ended up just being recolours in terms of avatars and in terms of voices... A slight adjustment on the parameters of another vocaloid. It was commonly associated also with the 2007-2009 period when CFM was ruling the roast with only about 5 other vocaloids to challenge them.

The whole practice is done for fun but never done for seriousness anymore.

Neru, Haku, etc got in and became famous during the period when it was best possible to do so. Oc's were a way of just taking a few vocaloids and seeing how far things could stretch. Now we have 70+ in total its not taken so seriously. The vast majority of fans aren't looking for OC works anymore. :-/
