3 Wishes

So I can only make three powerful wishes based on the Avatar The Last Airbender? But I can also make wishes from other worlds as well as my own cultivation world.

I can just wish for the power I had in my past world and my vast knowledge of combat skills as an Immortal Warrior. A God Slayer.

So with that, I go to make my wishes based on everything I know. I have these three wishes from the God I have just killed. I wonder what the limit is? I hold a golden glowing orb in my hand this seems to be the source of the three wishes.

Suddenly the orb starts shaking and I hear a robotic systemize voice.

[You can only select powers based on Elements and on Avatar the Last Airbender world- You can create new type of bending[EX: Blood Bending, Shadow Bending, Force Bending, Dark Matter Bending, and you can create eye powers all based on Avatar the Last Airbender]

[Use three wishes wisely. Some wishes may not be granted.]

What kind of bullshit is that? Whatever, I will make due of these restrictions. I go now to select my three wishes before I reborn into the avatar world.

___________

A/N: Select the most powerful bending. Yes the MC will be OP but it will be rise to power. The MC will be able to learn every element[ No spoilers on that. You will soon see why.] I am not sure if I should give MC Blood Bending as it is OP af in the avatar world. But I will see what I can do. Overall the MC will have the fire and lighting element as well as Airbending when he reborns but let me know which other powerful bending there is. Remember there is some bending that was never discovered until later like Toph creating Metal Bending. So yeah. Suggestions everyone.
