Vital Spirit
The Pokémon is full of vitality, and that prevents it from falling asleep.
Inner Focus
The Pokémon's intense focus prevents it from flinching or being affected by Intimidate.
When its anger rose beyond a critical point, this Pokémon gained power that is unfettered by the limits of its physical body.
It imbues its fists with the power of the rage that it kept hidden in its heart. Opponents struck by these imbued fists will be shattered to their core.
