How does Shuckle does the most damage?

Question

I know that with a combination of things, Shuckle can deal the highest damage from a single attack of any Pokemon. But how? Can someone tell me what the combination is (Ex: Items,Attacks, etc.)

Answer 1

"A level 100 Shuckle can potentially deal the most damage in one single attack through the use of numerous stat boosters; by using Helping Hand by two different Pokémon in a Triple battle, holding a Metronome, Power Trick, a Skill Swap to Pure Power or Huge Power, 6 Attack boosts, and a Mimiced Me First used on a slower Pokémon using the Defense Curl/Rollout combo. Also, Shuckle's partner must have the ability Flower Gift and the weather must be sunny. On the 5th turn of using Rollout consecutively without any misses, if used against a level 1 Ledyba, Yanma or Combee with minimum Defense stats, that have been hit with negative Defense modifiers (such as Screech), it can deal 481,266,036 damage with a critical hit." - Bulbapedia

Answer 2

Actually, the most damage possible can be dealt by Swampert on a Noibat as written here

In 6th Gen, the move Forest's Curse was introduced, adding a Grass-type to the target. A level 1 Noibat with the added Grass-type would be 8x weak to ice, which means that an Ice Ball from Swampert (after taking into account all possible items (Metronome etc.), all moves (Helping-Hand etc.) and all abilities (Flower Gift etc.)) would deal a maximum damage of 755,603,424

Hope I could help!

I've read through your source, and because of a small mistake in the calculation, the actual value was reduced to 566,702,568. However, by letting Shuckle use Mimic on Ice Ball, and using Color Change to get STAB, he reclaims the throne with a maximum damage of 721,899,013.
