The secrets of evolution

After Dian's Pupitar evolved, it seemed to have grasped how to use Earthquake, too, but he had never dared let it use the move.

The move's destructive power was too great and too widespread. He was afraid he would end up buried in debts he could never repay.

And when it came to how the League calculated damages... yeah, right.

In a sense, the essence of an earthquake was vibration. Intense vibrations triggered a series of changes that produced destructive effects.

An ordinary, natural earthquake was set off by nature itself. Applying that same logic to Pokémon, there was no fundamental difference. The source simply changed from nature to the Pokémon itself.

But how had Courtney's Camerupt managed to control the area ravaged by Earthquake, and even concentrate its power?

"Earth Power..."

Dian's gaze sharpened. That move was very likely the key to controlling Earthquake's power.

And the only Pokémon he had that could possibly learn it was Trapinch.

If the essence of Earthquake was vibration, then Trapinch's chain of evolutions was probably not as simple as people thought.

He quickly closed his eyes and began analyzing the moves available to Trapinch, Vibrava, and Flygon. He found faint connections to his theory.

Trapinch's evolution process was somewhat similar to Larvitar's.

Once Larvitar finally evolved into Tyranitar, its repertoire of moves underwent a dramatic transformation.

Although the changes in Trapinch were less obvious than those in Larvitar, certain differences still existed.

For example, after Trapinch evolved into Vibrava, it gained the Dragon type, but the only Dragon-type move it could learn was Dragon Breath.

Only after evolving again into Flygon could it naturally learn the more powerful Dragon-type moves Dragon Claw and Dragon Rush.

And that applied not only to moves it awakened naturally, but also to those it could be
