Suyin confirmed Korra to be the first metalbending Avatar in "Old Wounds". So unless you have canon proof that Aang also learned the skill to contradict the information given in that episode, that's what we're going with.
(On a side note, capitalizing each word of a sentence makes it quite hard to read them. Only the first word of the sentence and proper nouns should be capitalized.)
You had added "Metalbending (probably)" under Aang's skills. First and foremost, we do not add "probably" to this wiki in any case. It either is, or it is not. And in this case it is not, since we have no proof that it is. If Suyin of all people says that Korra is the first metalbending Avatar, having a close relationship with Aang and Toph herself, I'm sure she'd know if he was a metalbender.
You DON'T understand korra can not be the first avatar to metalband i knew that aang can metalbend Okay.😒
First off, no you didn't "know". Lets get that straight.
You might "think", you might "assume", you might "want" but you do not "know" this, because it never happened and it was never said that it happened.
I am asking you for references and evidence to support your claim that Aang was a metalbender. If you cannot provide references to the source material then unfortunately it is not canon, and it will not be on the Aang article
You Think i'm stupid no i'm not
All I'm asking is for you to back up your claims. If you can, then I'll happily let you add that Aang was a metalbender to the article. However if you cannot, then that information will not be on the article.
