"Listen, Smellerbee. Maybe we've been thinking about this all wrong. What if Yu Dao is neither Fire Nation nor Earth Kingdom?" — Sneers explaining his new stance on the Harmony Restoration Movement to Smellerbee.[1]

History
Sneers was a member of the Freedom Fighters, working as the team's scout. His job was to watch for approaching Fire Nation soldiers or anything else that could be deemed a threat or an interesting opportunity; in order to alert the other members, he would mimic a bird call.[3] After the end of the Hundred Year War and dissolution of the Freedom Fighters, he moved to Yu Dao and began a relationship with Kori Morishita.[4] Eventually, he became a member of the Yu Dao Resistance to protect both his relationship and new home.[1]
