If you were transported to the pokemon world but as a pokemon, which one would you be (barring legendaries and mythicals) also, keep in mind, this isn’t about which one is your favorite, it is about which one has the best chance for survival based in different criteria.
For survival?
Well, that’s easy. Carbink.
I mean, yeah, you’re rubbish at fighting, truly bottom-tier ludicrously bad. On the other hand, you basically don’t age, you’re composed primarily of diamonds and, consequently, you’re thoroughly inedible, impervious to most environmental hazards and, for all intents and purposes, indestructible. There are Carbink out there that are almost a billion years old – not the species, but individual Carbink. In Kalos, mind you, which means they’ve slept through Yveltal’s tantrums before. Time itself can’t kill these little fµ¢£wits, and it has tried.
