- It's a knockout! What a wingdinger of a hat trick, folks! Mako pulls off the upset of the season winning the match for the Fire Ferrets!

Shiro Shinobi provides commentary on pro-bending matches through the radio in Republic City.

History
He served as commentator when Korra listened to her first pro-bending match between the Fire Ferrets and the Tigerdillos on the radio from Air Temple Island. He was also present during Korra's debut match, where he remarked that she was a newcomer. Later, when Korra inadvertently revealed herself to be the Avatar, Shiro announced it over the air, which allowed Tenzin to track her down.
