each of em! water types ftw!
My Feraligatr, Bluetooth, has gotten me out of many, many jams on HeartGold.
JUST LIKE MY EMPOLEON, MY BEST POKEMON OF ALL.
Lapras, Hands down. Then Buizel as a close second.
current favorite: FUTACHIMARU!!!
Or perhaps Lumineon due to better colouration.
Gyrados or Daikenki. either one is boss to me. and of course i liek mudkip....
Most likely Futachimaru. Before it it was Squirtle.
Gyarados. I don't really like water-types, but that guy is such a mofo.
Swanna, Empoleon or Suicune
Empoleon, Gyarados, Samurott, Swampert, Milotic, and Vaporeon
In general I adore water types (they're mine 4th fav. type) so it's hard to pick only one, but in top 5: Starmie,Jellicent,Lanturn,Swanna,Empoleon
