VIPER

Viper (バイパー Baipā) is the holder of the Indigo pacifier of the Mist. He is a member of the elite assassination team, the Varia, under the name Mammon (マーモン Māmon). Known as the Arcobaleno's best spellcaster,Viper has the ability to cast illusions, as well as being able to locate any person by sneezing into a piece of paper (he carries a roll of paper with him); the spit or mucus that sticks to the paper shows a map leading to the desired person. He also has a black frog named Fantasma that lies on top of his head. By turning into a yellow salamander and biting its tail (Similar to the oroborus a symbol of alchemy and magic), which forms into a "halo" above him, Fantasma can give Mammon the ability to fly in combat.He claims to have been trying to break the Arcobaleno curse, and had sealed his pacifier so that other Arcobaleno cannot sense him.He has also created a chain that conceals the power of the Arcobaleno pacifiers, as well as the Ring Flames . During the Vongola Tournament, he defeats Chrome, however, he is defeated by Mukuro once the latter takes possession of Chrome's body.He is said to be dead in the future, with Ginger Bread claiming that he took his own life after feeling there was no other way out. He is voiced by Rumi Shishido in the anime.
