Hehehe... tch, well if it's tha ROM, then I guess my all lvl 100 sharked pkmn could make hundreds of teams. XD
If it's about tha games, then I guess that'd have ta be a LeafGreen party I have, tch, which consists of:
Charizard, Salamence, Rayquaza, Mewtwo, Kiara(Ninetales), an' Latias.
second party would be:
Charizard, Dragonite, Mewtwo, Kiara, Groudon, an' Suicune. ^^;;
