Suggested by Eric Bumi developed some Airbending skills once he was older, but they never reached the level of the other masters. Iroh is known as one of the strongest Firebenders in the whole series so this match is really no contest. A quick blast of fire will instantly incinerate Bumi’s confidence. Bumi simply isn’t much of a fighter while Iroh has crushed many opponents in the past. Iroh wins.
