Very true. For someone like Aang who has no experience fighting ninjas, the blood bend option in the avatar state would prove to be most effective.As a character, I like Aang more than Naruto (dont really like Naruto tbh.)
In a fight, I'd say Aang as well (under the assumption that Avatar State Aang can bloodbend, if he chooses to).
Aang can't blood bend. Naruto in BM or his KM clones should be enough to handle Aang.
