A firebender named Wuxian Yuan was on his way to work one day until he came across a weird man fishing on a close pond just besides the statue of the great avatar Korra,

He'd waterbend himself catching the fishes he'd catch which Wuxian didn't have time for to care until the man firebended himself some flames to cook up the fish, a waterbender that can firebend?

The man would also airbend to make the flames more bigger than before, the man was an avatar.
