This respect thread will be dedicated to everyone's favorite flying bison and lemur, Appa and Momo. Serious stuff, funny stuff, part funny part serious stuff, it can all go here.
Appa's basically a giant, lovable teddy bear (except he's a bison, he can fly, and he isn't a teddy bear). He provides transportation and comic relief, but when needed he is more than capable of holding his own or dominating a fight.
(The following will actually be serious stuff. Appa doesn't always fight, but when he does he's actually quite impressive)
In a world of preteen benders, Appa is a multi-ton heavyweight who is more than capable of making his presence known and drastically altering the outcome of a fight with his intervention. He's a physical powerhouse, as will be shown below
Pretty self explanatory. This was a tired, injured Appa too
This guy had Aang pinned down, but Appa's not having that
Appa to the rescue smashing through the Dai Li's wall like paper
Sky Bison were said to be the first airbenders, an ability Appa showed primarily in his flight. However, that was not the only form of airbending he was capable of.
A flick of his tail was enough to knock down all of these buzzard wasps
Mai and Ty Lee had beaten Katara and Sokka, but one flick from Appa solves that problem.
Of course, he is capable of more than just blasting people away
So, in all, while there's plenty of funny stuff to say about Appa, he's got some very solid, legitimate feats that make him quite the powerhouse.
Underestimate him at your peril
Lord Momo of the Momo Dynasty, His Momoness. Appa's faithful companion, and the secret ruler of the Avatar world. His power knows no bounds.
If you're not a Momo fan, you should probably just stop reading now, because only his true followers will understand.
Momo's fast, clever, and quite the little scrapper when he needs to be
Momo faced his greatest battle yet when he went up against Admiral Zhao, the mighty moon buster himself.
However, Zhao's tremendous moon-slaying ability did not keep the mighty Lord Momo from humbling him.
Truly a tremendous feat
No respect thread for Appa and Momo would be complete without this
And, of course, some acknowledgement of their incredible hiding abilities
Plenty more that could (and probably will) be added, but this seems like a good start
All hail Appa and Momo
