I Have the Answer to Mega Malamar

(Nah, you're good. I understand the exhaustion)

As the orb soars at me, the ground bursts into a wall. The Quetta-Moonblast breaks through but another wall stops it. It continues like this, the attack too strong to be stopped but the walls forming fast enough to keep it in place. This is a stalemate. However, vines also fly out the ground and grab you, dragging you under with bone crushing strength.

Interesting. I turn to light and fly away from it before turning back to normal and burning it all, including the ground, away with Never-Fading Divine Mystical Fires.

I let the world burn and teleport away, pursuing a chase on you

I snap my fingers and a Doomsday Power Ball gets launched from behind me

It is only a little weaker than your Moonblast, but it's enough to let me move out of the way

Then, I blast World Ending Fire straight at you
