The Legend of Korra

Seriously. Are we arguing how this bloodbending is overpowered and stupid, or that it breaks rules? The former is probably done discussion on this point; it rests on how the hell Amon resisted bloodbending. If the average joe can learn how to resist it, then it won't be OP, but if it turns out Amon was a waterbender or something, then essentially you won the argument.

The "breaking rules" part though extremely irks me, because never I have heard anything like that. There's no rulebook dictating how the 4 bending arts should be. Maybe Hama was a weak idiot; she didn't realize you could bloodblend outside of the full moon. Katara never attempted it because, well, she hates it. In reality, isn't bloodbending the same exact thing as metalbending? I'd argue that metalbending is even harder, as blood contains almost 50% water, while metals contain only specks. Maybe Tarlok and his dad were genetically/spiritually/whatever predispositioned towards bloodbending.

I enjoy this argument. Wish more arguments were like this.

Just going to throw in my two cents on the argument.

I personally agree with both that it is "overpowered and stupid" as well as the fact that it breaks rules (or rather, canon). I do prefer the term plot-hole for bloodbending in LoK though. Because if you cut the bull, Bloodbending is a huge plot-hole more than anything in LoK.

Breaking rules? I suppose I can agree that there aren't "rules." Yakone/Tarrlok break what the story has told viewers about Bloodbending, which is my problem. Maybe Hama is weak? I wouldn't think so. Though Katara was able to overpower her, Hama did pass on knowledge to Katara (sources of water, Bloodbending). And to boot she was clever enough to realize that the water in people could be bent, thus discovering Bloodbending. You're right on Katara, which adds to the whole plot-hole problem with Bloodbending. (Though you could argue that she planned her "visit" to the Southern Raiders intentionally on a full moon so she could use Bloodbending).

I discussed it on another forum about the Bloodbending plot-hole, and it's really just awful. Within, like seven years is what we decided, Bloodbending when from two people to serious enough to be outlawed. How'd it spread so fast given that the only known creator is either dead/dying in Fire Nation Prison and the other would probably never mention it to another soul?
