Well by looking at the Thread title and the Description! Lets compare teams from each pokemon game you've played in a list! ( Example : Pokemon Game: X, Team)So I guess I will start but I've pretty much played most of the pokemon but here! You can also add the levels and moves if you want to! But I really can't remember some of them!?

Pokemon Yellow: Pikachu solo run! Wow that was a hard game to complete with just a Pikachu!?

Pokemon Fire Red: Blastoise, Dragonite, Farfetch'D, Ninetails, Gengar and Alazkam. ( They are basically Haunter and Kadabra but I might as well put their final evolution!)?

Pokemon Game: Heart Gold: Meganium, Slowbro, Scizor and unfortunately I can't remember! This may be harder than I thought but I'll carry on!

Pokemon Game: Black: I used multiple pokemon switching out to others and leveling, so pretty much every pokemon I caught would be around 40-50. Or something like that!?

Pokemon Game: White 2: Samurott because I solo runned the game, I always do it once in per game!

Pokemon Game:  X : Dragonite, Mewtwo, Flareon, Vaporeon, Jolteon and Lapras!?

Pokemon Game Y: Can't think of the top of my head, but I'm doing a Wonderlocke!?

Well as I said that I played nearly every Pokemon game but! I can't remember all the teams on the top of my head or I can't find the cartridge! So I'm quite sorry about that but for now I'm just focusing on the new pokemon games being a lot of fun! Especially the Wonderlocke for Y version being quite a challenge! So leave a reply of your own end game teams! But for now I'll probably find out my old teams or not! ??

Guessing you edit your post some since it summoned me but none the less I can stay on topic.

On my white2 game I use pidgeot, emboar, samurott, garchomp, zoroark, and something else but can't remember since I haven't played it in awhile.

I do Solo runs with my starter on all games. I only have HM slaves.

So, Fire Red: Charizard

ruby : Swampert
