Talisman is a cunniving avatar who manipulates people in an internet chat to worship him and his rules. Things get crazy once Masatako Mido takes over the Talisman Avatar because he believes certain people unworthy of living in the real wold. Here's what Mido looks like: 

As Talisman - Manipulative voice with a booming tone , much like an announcer. Medium- low pitched

As Masatako Mido - Normal voice wth subtle creepiness.
