The true definition of "Mary-sue" is a 2D "perfect" character and not necessary "generic", basically its a character designed to fit any role and are unrelatable to the audience.

Their often used by writers as a cheap way of throwing in a character to fill a role, often as a last minute addition or for the sake of fluffying out the cast. Basically... A character thrown in to make up cast counts. The result is a boring or bland character the audience wants to choke, and is often a regard as bad or last writing.

I have yet to see a Vocaloid I'd count as "Mary-Sue", though most can be used in such a role, they themselves are not.
