Say what you want, I still think it's canon that Sokka is Suyin father. Also, Sparky sparky boom man is a terrible name, so I'm not siding with people in the comments. His name is Combustion Man to me!😜
Uhhhh.... Iroh is a war general with decades a training and bending practice and even met with dragons who showed him fire bending as well..... If he lost to a 14 year old girl no matter how much of a prodigy it would be pretty sad.
