My boy Kingdra here. If memory serves, I believe he was the first thing I ever evolved (from Horsea to Seadra), and for Catcher purposes, I consider Coral to be my 'main' partner. Coral was also the first thing I evolved after the new Catcher update, if you don't count Togepi - I got the Togepi in the earlier update, but it took a while to evolve it that it went past the update time.
magikarp to Gyarados, I think that was the last mon I evolved I haven't evolved anything is so long. XD
Do eggs count? If so, it would have to be my Articuno, Shaved Ice. If not, it would have to be my Jolteon, Syrup.
There's clearly an inside joke I'm not getting here; I was just thinking of this card. I feel as if I'm missing out, but on what? and do I not want to miss out now?
Eevee into Vaporeon. I'm currently looking forward to evolve my caterpie into Metapod and then into Buterfree.
Sprout became a Venusaur a couple of months ago. Since then I decided to try and hatch some of my eggs.
The most recent thing I evolved was a Phanpy. I'd forgotten this topic existed, perhaps because it was buried. I'm steadily working on stuff that I like, though now I think I'm out.
