Zubat

Forms colonies in perpetually dark places. Uses ultrasonic waves to identify and approach targets.

Supersonic: Flip a coin. If heads, the Defending Pokémon is now Confused.

Leech Life (10): Remove a number of damage counters from Zubat equal to the damage done to the Defending Pokémon (after applying Weakness and Resistance). If Zubat has fewer damage counters than that, remove all of them.
