Do you mean this?
>"Although the circumstances would be nearly impossible, a level 100 Shuckle can potentially deal the most damage in one single attack through the use of numerous stat boosters, Metronome held item, Power Trick, a Skill Swap to Huge Power or Pure Power, and the Defense Curl/Rollout combo. On the 5th impact of Rollout, if used against a level 1 Ledyba or Yanma that have been hit with negative Defense modifiers (such as Screech), it can deal over 210,000,000 damage."
So over 210,000,000 :P, well apparently it's 213,000,000
