Hoping for the Regis, though not actively looking for, and keeping my eye out for that last Eevee too. It's still evading me.
My Sableye hunt has finally come to a close, so now I want... huh, not sure what i want actually. X_X I guess I'll just wait for a surprise!
Now that I caught shadow boi... Spiritomb I guess? No idea where to find him >_> Maybe he'll be a swarm or something, but I have not seen that dude ONCE.
Just caught Ho-oh, so I can honestly say I'm not interested in a whole lot at this point besides either Regice and Registeel, or as I said previously, Raikou. But I'm not in any sort of rush to catch those in the slightest.
I'm not really hunting anything right now. I'm mostly just catching pokémon that I like if I haven't already. If I see a Croagunk though, I definitely am going to want it. Croagunk is quickly becoming one of my favorite pokémon, and I would love to find one.
I'd like to catch a legendary bird or obtain a Kanto legendary egg. I have only seen ones for Hoenn, Sinnoh, and mythical eggs so far.
