Zaheer is on the back foot initially. He only really wins because he had a glider. In additon, the main reason for his victory was due to the plot. The creators couldnt have the mian villian who has been hyped up for the past few epeisode lose, could they?
All in all, Kya does much better against Zaheer than she does Ming-Hua. In her fight with Ming-Hua, she was on the back foot, with Zaheer, it was blow to blow. Without a glider, she wins.
Desna and Eska on the other hand have given Korra trouble and we're just impressive in their power and teamwork altogether.
@deathhero61: I don't see how its a stomp. Azula vs. Haru is a stomp.
As for your comment about about Aang. Initially, Aang held his own quite well against Ozai. He was on the defensive, but was holding up. He seemed to shy away from going on the offensive. He was a pacifist and was against killing Ozai. Things only seemed to go down hill for him when he redirected Ozai's lighting and subsequently lost the will to continue fighting. IMO, a bloodlusted Aang could have defeat Ozai without the avatar state.
This would be a good battle, but JJ would win. Jeong Jeong was a firebending master. No other fire bender outside the comet could produce the amount flames he did with his fire wall. He also rivals Ozai and Iroh with the comet and demonstrated more powerful fire bending techniques
Supergirl takes both rounds. Granted, Wonder Woman is arguably just as strong and is without a doubt more experienced. However, her endurance and durability may become an issue. In contrast to WW, Supergirl has the yellow sun constantly healing her and replenishing her strength. Diana's stamina will eventually run low
First round, it wouldn't be easy but the duo could probably manage something. Individually, both WW and Marvel rival Superman and can hurt him. Marvel held his own against Supes. Add WW and as team, they should equal him. Supeman wins round 2. No one(except Darkseid & Mongol) are taking a bloolusted Superman who is convinced that you've kidnap Kara
Pakku and Unalaq take with medium difficulty. Both of them can create very powerful waterspouts. Unalaq on his water spout he had great mobility, he was quick and very fast. I just do not see the fire benders landing a shot. On top of that he could fly whilst on it. Not to mention, he was tanking and dodging AS level attacks, which is an impressive feat. Pakku on his water spout was surrounded by dozens of FN soldiers and non of them could even land a hot.
