Huh,
Zaheer from Korra was voice acted by Henry Rollins.
We’re on Season 4 of Korra now. It’s watchable, but every season has the same diabolical bad guy archetype, and he’s always defeated by Korra tapping into more power than you they said she had. I think Dragonball-Z works like that?
The original Avatar had way more weirdness like the Face Stealer and haiku contests, and it had the benefit of the characters not being near the height of his powers, so they had to actually do things other than blast guys with powers.
I will say it is way better than when we had to watch Paw Patrol, a few years back.
