What if the avatar was a champion?(Random Thoughts)

Does anybody remember that show from 2005 by nickelodean called Avatar the Last Airbender . Well, recently I rewatched it and thought about how it could be a champion. In no way am I saying this should or could be a thing, it's just a random thought. I wouldn't imagine this avatar to be in any particular part of the cycle, or to be anyone that either ATLA or LOK(Legend of Korra) has introduced.

Passive: Avatar State: When the avatar drops below 40% of maximum health they enter the avatar state for 10 seconds. During this time all of their abilities are empowered. On top of that, there is no "ultimate" ability, the avatar's r is simply like another ability, and can be learned at level 1.

Q:Firebending: The avatar sends fire in a target direction, dealing 90/130/170/210/250+(70% ability power) damage. In the avatar state the range of this ability is increased by 250, and the scaling is increased to 90% range:900 cooldown:10/9/8/7/5.5

W:Airbending: The avatar airbends in a target direction moving all enemies 100/150/200/250/300 units back, this will interrupt dashes. In the avatar state this will send enemies to the range threshold. passive:Have a 5/7/9/11/15% chance to dodge basic attacks. (I know this is RNG but it's based off of how evasive Aang was in the show as an airbending master.) range:900 cooldown:15/14/13/12/10

e:Waterbend: The avatar creates a ring of water around themselves for 5 seconds, this ring will block any basic attacks or on hit abilities, then it will send a surge of water back at the attacker dealing 20/30/40/50/70+(20% of ability power)(20/25/30/35/40% of that attack's damage).In the avatar state the return percentage ratio is increased by 15%. Basically the more powerful the attack the more powerful the return(in the avatar state this increases). This only procs on champion on clicks or basic attacks. return maximum range:1000 cooldown:20/18.5/17/15.5/14

R:Earthbend: First cast: Create a wall of earth that is 500/600/750 units wide. Second cast:Move the wall forward 150/250/400 units, pushing all enemies caught with it, if it collides with a wall all enemies affected will take 90/140/190+(60% ability power) damage. In the avatar state the walls width is increased by 250 and the scaling is increased to 75%. cast range:650 cooldown:20/18.5/17/15.5/14

If you haven't watched the show I recommend it! And thank you for bothering to read this idea!
