|Manga Debut||Chapter 90|
Fantasma is Viper's animal partner. Originally a dark green frog, when Viper's Arcobaleno powers are released, it becomes a yellow and white Salamander that bites its tail with its head to form a halo, allowing Viper to float; the manner in which Fantasma does this makes its appearance similar to the ouroboros, a symbol of a Snake eating its own tail. This is a symbol commonly found in the studies of alchemy and also in magic.
- Fantasma is the Italian word for "ghost."
