That, while every fight in both series is absolutely incredible. it’s the fights between two masters of the same element which end up being consistently spectacular?
The fighters start on even terms, they use the same element, so there is no strategy available to them which isn’t also a valid one for their opponent to use, this means the fights come down to speed, skill and endurance, the loser is the one who blinks first… this racks up the intensity and pace of the fight considerably.
Fights of this nature which I really wanted to see in this form but never got:
Toph vs Kuvira (would be pretty awesome, but one sided in Toph’s favour)
Toph vs King Bumi (Toph at her peak would beat Bumi back, but we also never saw him at his peak. so that could be interesting)
Mako vs Iroh II (haven’t seen enough of Iroh II to judge, but I reckon it’d be pretty even.
And potentially the most awesome
Uncle Iroh vs Ozai. WE NEED TO CROWDFUND LIKE AN OVA OF AWESOME FIGHT SEQUENCES OR SOMETHING.
