Chapter 521 - 520: Shiny Metagross!
Two Metang began emitting a bright white glow.
It was the light of evolution.
Steven's expression lit up with joy.
He had invested so much in training these two Metang. With the resources of the Stone family and Devon Corporation, anything Steven could acquire, he immediately provided to his Metang.
As his first Pokémon, Steven shared a deep bond with them. He had always worked hard to train them, even asking Cain to prepare special Pokéblocks tailored for Metang to help them grow better.
In truth, one of the Metang had reached the level necessary for evolution long ago, but it lacked its other half, which prevented its evolution. That's why Steven focused on training the second Metang.
Not long ago, both Metang reached the same level, but for some reason, the anticipated evolution didn't occur.
The last time Cain called him, Steven had been out searching for special stones, hoping to trigger the evolution, but he hadn't shared those details with Cain.
Despite his earlier efforts, the evolution didn't happen.
Now, however, after defeating the quasi-elite-level Camerupt, the two Metang began to emit the light of evolution.
Naturally, the two Metang moved closer together, and their auras evolved in unison.
