From Bulbapedia, the community-driven Pokémon encyclopedia.
I'm not sure if this is where I should put this, but the discussion about the max damage Shuckle can do has been going on for a little while, and I think this Smogon thread[http://www.smogon.com/forums/threads/new-contender-for-most-damage-possible-in-pokemon.3502735/] shows the max damage in Gen VI as being 12,085,363,749. It involves a Huge Power Fire-type Flash Fire Shuckle using V-create (through Mimic) to a Dry Skin Steel/Bug/Grass-type Gastly (through Reflect Type and Forest's Curse) in the sun, and a lot more.
Again, I'm not sure if it really matters or not, but I just thought it would be neat to share.
