From Pokémon Revolution Online Wiki
Body Slam is a Normal-type damage-dealing move.
Body Slam inflicts damage and has a 30% chance of paralyzing the target.
- Unlike in the original games, Body Slam can miss against a Pokémon that used Minimize, and does not deal double damage to it. (Report thread)
Body Slam can be taught via Move Tutor at Saffron City's Dojo for the price of 15,000.
