Xingye vs. Giovanni, Mewtwo's Immortal Body

Massive tremors spread throughout the Tree of Beginning, affecting even Kabukicho above as the area of collapse continued to expand.

Fragments of the streets began falling nonstop, destroying forests and rivers. Many branches of the Tree of Beginning were smashed apart and plummeted down as well.

Many Fossil Pokémon that had only just awakened from their long slumber failed to grasp what was happening before they were buried beneath the falling debris. The rest fled in panic, crying out without stop.

At the same time, many people fighting in Kabukicho failed to escape in time and fell along with it, dropping down like dumplings into a pot.

And the collapsed area was still expanding. Once Kabukicho completely caved in, Hau'oli City—and perhaps even all of Melemele Island—would vanish from the map of Alola...

"What the hell happened?!"

Nemona and the others fled in panic, but they could not outrun the collapsing ground. Their footing soon gave way, and they fell together. Countless other people and Pokémon suffered the same fate, shifting the battlefield below.

Unable to fly, Groudon lost its footing while battling Rayquaza and fell, taking Maxie down with it.

No one else nearby escaped either. Zinnia immediately had Rayquaza whip up a storm to catch them. Riding on Rayquaza's back, she stared below in shock. "What is this...?"

Zygarde flung away the Xerneas and Yveltal it had been holding, then flew out to catch those falling. Looking down below, it said gravely, "The order of the Tree of Beginning is collapsing? This is bad! We have to..."

Volo jumped onto Giratina's head and calmly watched the scene before him. "Something like this actually happened. Does he intend to make Pokémon disappear from this world? I don't exactly oppose it, but this puts me in a difficult position too."
