Nero

Nero is a fan character.

Characteristics
Nero is a virus/antivirus hybrid disguised as a black-and-white wolf. His hair is jet black and his inner ears, belly and parts of his tail are black, as well. In Anti-Viral mode, his eyes turn heterochromic black/white and his hair gains some white highlights.

It was confirmed that Nero was the older brother of both Bella and Luna, and that they are derivative from his programming. As the eldest, he sees it as his duty to keep the peace between the girls (although the doesn‘t really work) and always has advice for them. Coming from the cyberworld and virus/antivirus war, he sees no reason to result to violence. This does, however, change if a member of his family is in trouble or being harrassed.

Overall, Nero is a mature, gentle (yet assertive) being. Many would consider him a role-model and mentor to the younger characters.
