As long as you have more Prize cards left than your opponent, Vespiquen's attacks do 10 more damage for each Pokémon on your Bench to the Active Pokémon (before applying Weakness and Resistance).

After your attack, remove from Vespiquen the number of damage counters equal to the damage you did to the Defending Pokémon.

Flip 2 coins. If both of them are heads, the Defending Pokémon is now Burned, Paralyzed, and Poisoned.
