Who was the fist avatar?

Answer 1

To me the strongest avatar would have to be Aang. My reasoning is that, at least in the avatar state, you are given the power of all past avatars. So say an avatar 10 lifetimes ago would lake the power of those 10 avatars in the avatar state while Aang would have that power. It just makes sense to me, at least when dealing with raw power and strength. But then if we don't talk about avatar state, from what I understand, all benders are created equal, and by that I mean it is more technique and skill that make a bender more powerful, so in that respect, although Aang is amazing, he is still only a child. One of the older avatars would be more skilled at fighting I am sure. But since Aang is also the only Avatar to be able to remove someones bending from what we can tell, then I would say it doesn't matter. Well that was long but to wrap it all up, Aang has pure power in avatar state, plus he has an extra type of bending, but his technique could use some work. But I still say Aang and not because he is so cute and adorable!!

________________________________

The strongest Avatar I would have to say is probably always the current one, since he/she has access to the Avatar State, which is the combined power, and knowledge all of the past Avatar's. Plus Aang is the only Avatar yet to use what Wikipedia calls "Engerybending" a type of special bending only the avatar can perform, it has the ability to forever take away someone else's ability to bend their respectful element. But if you wanted to talk "outside" of the Avatar State, then things might get a little complicated, even though by the end the the series Aang has mastered all 4 elements, I'm sure there might be some older, more wiser, Avatar's that may be better in fighting terms, as they have also mastered the 4 elements, and if you really wanted to find out which Avatar was the strongest, you'd have to determine which element is the strongest as well, because all Avatar's have their own respectful elements that they were originally born into, and since Aang's original element is Air, you can tell that throughout the entire series, Air is the most element Aang uses, and is comfortable with, and most powerful with, so I'd assume that every Avatar, although has mastered all 4 elements, is more fluent in their original element they were born into, and if that's the case, you can't really determine which element is the strongest because all elements have their weaknesses. Earth yields to Fire. Fire yields to Water. Water yields to Air. and Air yields to Earth. If two Avatar's were to battle one another, my guess is that it would be a tie.

Answer 2

His name was Wan. We learn about him and how he became the first Avatar through flashbacks in Season 2 of The Legend of Korra. We also learn what the Avatar state really is and why the eyes glow when in that state, the reason for the reincarnation cycle, and why the bending elements have to be learned in a specific order

Answer 3

Aang, would be the strongest being the avatar he has the most strength!
