Viper is an Arcobaleno, the holder of the Indigo Arcobaleno Pacifier. Also known as Esper Mammon, they work for the Varia, the independent assassination squad of the Vongola Famiglia. As the Varia's best spell-caster, Viper can construct powerful illusions as well as being able to locate any person by sneezing into a piece of paper. Their animal partner is Fantasma, resting on top of their head.
Viper's gender was never revealed in any form of Katekyo Hitman Reborn! media. Gender-neutral pronouns are always used to describe them. In VIZ translations, their gender continues to remain as male, though VIZ itself is not "official" and has become infamous for making many errors and not adhering to the original text when translating. In the stage play, Viper is portrayed by an actress, Chihiro Kai.
Viper has fair skin, purple hair, and purple upside-down triangle markings on the cheeks. They wear a black cloak with white stripes on the hood that always cover their eyes. Viper wears their Varia uniform over the cloak. The Arcobaleno Pacifier is on a thick chain around their neck. The pacifier was previously covered by Mammon Chains, and now concealed by the Auto Mammon Chain Ring Cover. They wear their Varia uniform over the cloak.
As the representative of Greed, Viper is materialistic, and is generally apathetic. With some exceptions, they only work when money is involved, and tend to charge very high prices for their services. On rare occasions, Viper works for free only if the situation is dire or out of their duties as an Arcobaleno.
Breaking the Arcobaleno curse elicited more emotions from Viper. They expressed their desire and determination to break the curse and to continue living.
