Hey, there, Simon! I believe I saw you in the chat before, but I wasn't really talking a heck of a lot, and just wanted to make a more proper introduction! You can call me Yuki, and I welcome you to the site! It's great to know you have roleplaying experience, and I'm sure you'll fit right on in!
As for your character, it's perfectly alright to me! We don't hinder creativity here - you're character is your character, and you have freedom to do what you please, so don't fret! ^^;;
And, about the 'Machine bending.' It's not an official bending element at the moment, but I would say 'Metal Bending,' would be your closest bet, for the time being, that is. It's always a possibility that it may be added later on in the plot, but as of right now, I can't guarantee is it. I'd recommend speaking to the either of the head admins, Fire Lord Kouzai or Earth King Lu about it, though!
Anywho, I hope you enjoy your time here!
