Your oldest surviving Pokemon?

[Mockingjay]

I had a level 100 Swampert on Ruby/Sapphire 9 years ago. I moved him to Pokemon Pearl, but I lost Pokemon Pearl a year ago. I'm still searching for it..

Other than him, probably any other Pokemon on my Sapphire/Ruby game; they're all the same age basically. xD

I have my original blue version with all my mons still on it. The oldest mon that I still have in B/W would be my WSHMKR Jirachi and I think my Sceptile.

My shiny blaziken from pokemon sapphire named Flame, he's going on about 7 years now.

Well, my traded lvl 15 Petilil which is now a Lilligant and is totally awesome, I just love that thing, its as strong as my Emboar.

Teh Ultimate WARH-TURH-TULGH came from meh FireRed game in 2004, it's about 7 or 8 years old. Though my oldest in my oldest game would be my good ol' Swampert from Sapphire. It's like 9 years old, it's still in my Sapphire game, I wonder if I should transfer it :/

My oldest surviving pokemon is my Swampert from Ruby, which is now in my SoulSilver version. I've been having problems with my SS game freezing randomly, so I think I'll transfer it to White soon.

My Mudkip from Sapphire. I got the game on release day and got Mudkip few months later. It's fully evolved now and I still have that save.

I've got a lvl 87 Blaziken named Torch from Ruby who's currently working out dominating the Sinnoh E4 in Pearl until I can transfer him to Black. He's part of a team with my lvl 82 shiny Altaria, a lvl 75 regular Altaria and a lvl 80 something Milotic.

My Togekiss called Iggy Pop from Pearl. He's the only Pokemon I've ever raised to Lv 100 from just training and he's a Pokemon that means a lot to me. I'd never think about getting rid of him and I ensure that whenever I start a new game he gets transferred across. <3

I've still got my Sceptile from my Sapphire version I got in 2004. I never really use it much, but I migrated it over to HeartGold so I could start a new file on my Sapphire. I've got about a dozen others from my original Sapphire scattered throughout my other games, too, but they obviously came later.

Unfortunately, I use to delete my data all the time. Because of this my oldest Pokemon is probably something from Ruby, Sapphire, Colosseum, or Emerald from 2004 or 2005.

I also recall losing many of my GBA Pokemon in Diamond due to a hacked Pokemon I received on the GTS that somehow corrupted my file.
