This The Legend of Korra papercraft is a Mask of Amon. This mask paper craft is designed by KaiserLee. Amon is the charismatic and mysterious leader of a group of chi blockers known as the Equalists, whose ultimate goal is to create equality by ridding the world of benders. A nimble and stealthy fighter, he is fearless in facing his opponents, regardless of their bending skills.
Amon was born on a small farm to a poor family of non-benders; nonetheless, they were extorted by a firebender. When Amon's father eventually confronted the bender, the firebender killed his family and deformed Amon's face, resulting in him wearing a mask since then.
Amon sounds very similar to Anon - short for Anonymous, an internet movement or concept of anonymous activists who protest political injustice. They often use a Guy Fawkes mask as a symbol for the movement and as a disguise, which is similar to the mask Amon uses.
