Something Important

Poliwrath was about to reach Elite Four level. After activating Golurk, the next step would be the Crystal Lake arc...

Poliwrath's Mega Evolution?

Would it use bonds?

Or a Mega Stone?

But bonds required Aura, and the Trainer needed Aura too. The protagonist did not have Aura. Now that it had come this far, should I give the protagonist Aura?

Actually, I preferred for the protagonist to remain an ordinary person...

Without Aura, the only path left was a Mega Stone. But neither the anime nor the games had a Mega Stone for Poliwrath, and Poliwrath could not Mega Evolve...

So I wanted to ask everyone here.

Which kind of Mega Evolution would you find more acceptable?

Could I write in a Mega Stone for Poliwrath out of nowhere?
