I don't remember their EVs and never knew their IVs, unfortunately. But here:
~ Donphan (Adamant): 350/372/276/113/156/157 {Ice Shard, Earthquake, Stone Edge, Seed Bomb}
~ Nidoking (Naughty): 303/311/190/203/167/269 {Megahorn, Earthquake, Stone Edge, Sucker Punch}
~ Hippowdon (Impish): 416/258/364/144/168/125 {Ice Fang, Slack Off, Earthquake, Stealth Rock}
~ Yanmega (Timid): 302/162/204/331/143/317 {Bug Buzz, Air Slash, Hypnosis, Protect}
I could get an IV/EV checker code, I guess. *shrug* I got them back when IVs didn't matter so much. :P
