Pikashunium Z
From Pixelmon Wiki
NOTE
Cap Pikachu isn't yet in the mod, but it'll be in future releases.
The Pikashunium Z is a Z-Crystal exclusively for Cap Pikachu.
Moves this Z-Crystal can upgrade:
- Thunderbolt → 10,000,000 Volt Thunderbolt Special: Only a Cap Pikachu can use it. Regular Pikachu can't use it.
Moves, abilities or items like Embargo, Klutz or Trick can't make a Pokémon drop the Z-Crystal that it's holding.
