I got Typhlosion close in Silver and Rayquaza close in Emerald.
But I don't even bother anymore.
Though I ought to get them up to at least 50 for battle frontier uses.
lv18 Azumarill doesn't help. xP
But wifi takes care of everything, so I don't feel the need.
ummmm.........let me think about that. <a href="http://www.pokeplushies.com/feed/1506506"><img src="http://www.pokeplushies.com/images/adoptables/1506506.gif" border="0"><br>Click here to feed me a Rare Candy!</a><br><a href="http://www.pokeplushies.com">Get your own at PokePlushies!</a>
Also working on my Platinum team of four, who are all currently around lv.80. All Gen.III 100s currently reside on Diamond, and Buzz and Rayne have been relocated to Platinum to help train the new team and earn some Battle Frontier standings. I refer to "Pokémon" as my addiction.
Currently none because I restart the games so much that I don't get a chance to level up my pokemon. Expect for my longest game(silver) which I believe had over 150 hours and IIRC I had a Typhlosion, Pidgeot, Rhydon, Espeon(?), Ho-oh and Suicune as the only level 100 pokemons.
I have a friend who's sole enjoyment of the game is to raise his pokemon to level 100, but I prefer to just raise them to about level 65. With full EVs, I don't think it matters what level the pokemon is on.
