1. Who’s your favorite STARTER POKEMON?
I don't have one overall, since I am entirely too indecisive... but for each generation:
Gen I: Charizard
Gen II: Typhlosion and Feraligatr are tied
Gen III: Sceptile (although I prefer Grovyle)
Gen IV: Infernape
Gen V: Samurott
Gen VI: Chesnaught
2. Who’s your favorite LEGENDARY POKEMON?
Raikou overall. Otherwise, we have:
Gen I: Articuno
Gen II: Raikou (redundancy department of redundancy is go)
Gen III: Latios
Gen IV: Darkrai
Gen V: Reshiram
Gen VI: Yveltal
3. Who’s your favorite EEVEELUTION?
Umbreon. Jolteon is a reasonably close second and Leafeon a similarly close third.
4. Who’s your favorite SHINY VERSION of a Pokemon?
Charizard, Pidgeot, Ninetales, Seadra, Umbreon, Absol, Duskull, Rampardos, Victini, Liepard... just off the top of my head, there are too many nice ones. I think it's Ninetales overall, though.
5. Who’s your favorite ALTERNATE FORME?
Overall it's... Giratina's Origin Forme, I guess? Honorable mentions go to Fan Rotom, Deoxys' Speed Forme, Shaymin's Sky Forme, Keldeo's Resolute Form and... I'll toss Dandy trim Furfrou in there for good measure.
6. Who's your favorite REGIONAL RODENT?
Linoone. I must admit that Rattata and Raticate are classic, though.
7. Who's your favorite PSEUDO-LEGENDARY?
Dragonite. I'm quite partial to Tyranitar, too.
8. Who's your favorite BABY POKEMON?
Uh... Budew? I don't care for the majority of the babies, to be honest...
9. Who's your favorite Pokemon (in general)?
Pidgeot. Until the end of time, I would say.
Look at me making this post so much longer that it needs to be. Like a champ.
