Wailord is 44 feet long while steelix is 31 feet. The most dangerous is mewtwo. If deoxies stats are close to mew's, celabei's, or jarichi's, then it is no contest. At level 100, mewtwo has almost 400 s.a.. I highly disbelive deoxies has even 300 s.p.. As for most cheerful, what about pulse or minun? They cheer, even if their getting hit with any attack.The rarest has to be one of the ladendery pokemon. If you fish out one female febass, then you can lay eggs to get more of them. Next,you feed two of the febass all the coran berries it can eat. Once you do that, You just have to level it up once. There you go, two fresh milotic. One question: How does eating grass make you heveay? I think the pokemon that most go on a diet is slaking, eating only the grass near it. The most mysterious is shedinja. It does not even move or breath. It is probly the lazyiest and dumdest pokemon.
