This Is The Finalized Version(s) Of My Bending Chart. I Overhauled The Whole Thing And Updated Some Of

Avatar:  Glory and Shame

Personally, I think Mike and Bryan get too much credit for what was really a team effort.  A good team balances out each other's weaknesses.  While making Avatar, Mike and Bryan were balanced out by other great writers.  However, Korra was mostly made by Mike and Bryan, so any personal biases they might have don't get edited out.  

Taking all the glory also means taking all the shame. 

Let’s talk about Zuko. And since it’s October, let’s talk about “Creepy Zuko”. And how Ozai’s abuse has effected his children.  

I've been playing a lot of "Legend of Zelda: Tears of the Kingdom" and this is my idea of what a "Bionicle Version" would look like. You'd go to the different temples to gather each element, and the Nuva Gauntlet would change color depending on what element you're using.

Where Wisdom and Valor fail, all that remains is faith.  And it can overcome all

Avatar: The Last Airbender premiered on this day sixteen years ago!

The Boy in the Iceberg and The Avatar Returns first aired on February 21st, 2005.

Maybe that’s why Katara was so upset.

This is my most current elemental chart for Avatar the last Airbender.  It’s gone through many different versions but I’m really happy with how this one turned out.  

I’ve included my old versions for reference.  

Central area:  The four classic with Energy bending in the center.  

Inner Circle:  Basic sub-skills most benders can use.  

Outer Circle:  Advanced sub-skills that are difficult to learn.  

Outer Edge:  True power of the Element.  Only achieved when you master the spiritual side of that Element.  

AIR

AGILITY:  Heightened sensitivity, speed, and reaction.  

LEVITATION:  Able to float in the air.  

VORTEX:  Able to send air compression blasts at your opponent, similar to a vortex cannon.   

CLOUD:  Able to create a cloud to ride on as seen in LOK and “Journey to the West”.

WATER

ICE:  Able to bend Ice and turn water into Ice.  

HEALING:  Able to energize water for healing purposes.  

PLANT:  Able to bend plants by bending the water in them.  

BLOOD:   Able to bend animals by bending the water in them.

EARTH

SAND:  Able to control earth as sand, dirt, or a granulated state.  

METAL:  Able to bend metal.  

MINERAL:  Able to bend large Crystals.  

LAVA:  Able to bend Lava or earth in a molten state.  

FIRE

FLAME:  Able to alter your flame in fire bending.  Make it hotter = blue fire.  Also includes sensing chi with fire.  

LIGHTNING:  Able to produce or redirect lightning.  

HEAT:  Able to manipulate heat.  

COMBUSTION:  Able to make explosions with firebending such as Combustion Man, or when Zuko failed to learn Lightning bending.  

“You and me, brother. The showdown that was always meant to be: AGNI KAI!”

Also, probably the best animated fight I’ve ever seen, a heart-wrenching tragedy, and also callbacks to All The Things.

You remember Zuko’s Agni Kai with Zhao? Remember his previous fights with his sister? Remember his 540 degree turn?

Well.

How would a person actually find out they have the ability to bloodend and if it's possible to know without training to do it.

Of the four bending arts Waterbending is most versatile and adaptable. After all, it is the Element of Change.

Waterbending is also the only element where most people can learn ALL the subtypes. (Provided they spend the time to learn.)

So to answer your first question: Most waterbenders have the ability to bloodbend but also need three things:

A deep understanding of the body and its anatomy, which is usually gained after becoming an expect healer.

Immense bending strength. Bloodbending works by dominating the water and Chi in another person’s body. A bloodbender must be strong enough to overcome their victim's Chi.

The Full Moon. Most waterbenders do not have the strength to overcome another person's Chi, therefore they need the added strength coming from the full moon in order to bloodbend.

All in all, bloodbending is a master level ability which can only be learned by very strong or master waterbenders.

As to your second question: 'Can someone know bloodbend without training?"

Answer: No. Bloodbending requires too much skill to be done by accident. (Just like you can't accidently do Calculus.) It's a skill that has to be learned and developed.

Apologies for taking so long to reply.

ATLA vs Korra:  Which is better?

Personally, I think “Avatar: The Last Airbender” was better than “Legend of Korra” for one specific reason, which I hope you'll agree with.  

ALTA was able to achieve its full potential Whereas Korra never got that chance. (Do you agree or disagree.  Post your thoughts below.)
