It was the best fit for the current situation.
The Evolution Light flashed and faded in an instant as Mega Metagross moved to meet Grimmsnarl's attack.
Grimmsnarl's signature move was called...
G-Max Snooze!
A massive ball of Dark Energy descended like a black sun.
It was even more powerful than the previous Gigantamax Barrage, and along with it came a drowsiness that made one's eyelids heavy and one's mind sluggish...
Even with Mimikyu's energy covering him, Roy felt a hint of sleepiness under that terrifying drowsiness.
He bit the tip of his tongue, using the pain to sharpen his mind as he sent an order through Aura transmission.
"Metagross, Absolute Defense State!"
This was the third form developed within the World Tree.
Unlike Weightless State and Super-Heavyweight State, this move could only be used while Mega Evolved.
A deep blue light lit up in Mega Metagross's eyes. Using Calm Mind, it instantly entered Absolute Defense State.
Light Screen...
Iron Defense...
Reflect...
Cosmic Power...
The immense psychic power of its eight brains after Mega Evolution was converted entirely into defense in that instant, supplemented by Steel Energy tempered beneath underground pressure...
Mega Metagross in Absolute Defense State embodied true invincibility.
Its four arms crossed before it as it faced the black-sun-like ball of Dark Energy head-on.
Boom!!!
The massive Dark Energy roared and rampaged. Its power was enough to corrode everything, yet it could not leave a single mark on Mega Metagross.
Grimmsnarl furiously increased its power, determined to break through Mega Metagross's defense.
"Just as brainless as expected." Light bloomed in Roy's right hand again. "We aren't fighting alone..."
Nature Power drew in, and Roy transferred the golden torrent of energy around him to Blastoise.
Grimmsnarl was Dark- and Fairy-type, immune to Psychic moves and highly resistant to Ghost-type moves.
