The Gecko

The Gecko was a contestant in the underground earthbending competition, Earth Rumble VI. He used unusual tactics during battle, some of them being that he crawled on all fours and used his earthbending to scale walls. He relied on his quick speed and agility to climb around the ring to stay out of the grasp of his opponents. He wore a distinct mask resembling a tree gecko.

History
He was easily defeated in his match against The Boulder during the tournament, and later helped Xin Fu kidnap Aang and Toph, holding them for ransom. When Toph was traded free for the money, she battled and defeated each of the Earth Rumble VI fighters, including The Gecko.

Trivia

 * In The Blind Bandit commentary, Bryan Konietzko stated that The Gecko was based on the W.W.E. wrestler Rey Mysterio.
