Character info
The character
Slowbro is a Water/Psychic-type Pokemon known for its laid-back demeanor, a result of a Shellder biting onto its tail. Mega Slowbro is its Mega Evolved form, in which the Shellder clamps onto its face, granting heightened Psychic power while leaving the Pokemon in a near-constant daze. It is recognized across the Pokemon franchise as one of the stranger and more whimsical Mega Evolutions.
