Here are a few Pokemon I could see them having
Ciel: Altaria, Talonflame, Crobat, Skarmory, Staraptor
Adrienn: Florges, Togekiss, Klefki or Mawile, Azumarill
Titania: Scizor, Bronzong, Steelix, Magnezone, Aegislash
Amaria: Lapras, Wash Rotom, Kingdra, Ludicolo, Swampert
Hardy: Gigalith, Aerodactyl, Tyranitar, Aggron
Saphira: Dragonite, Dragalge, Goodra, Salamence, Tyrantrum
I think it would be the Elite 4 or Lin.
Gym Leaders have 6 Pokemon and field effects, and it would make sense if the Elite 4 went beyond that to show that they're stronger than the Gym Leaders. (not that megas would be the only way to do it, but yea)
I voted B at first, but reading the posts made me change my mind, mainly because of the level-up moves/Heart Scale thing. I remember hoping my Eevee evolved into Sylveon before level 39 so I wouldn't have to use a Heart Scale to teach it Moonblast (fortunately, it evolved at 31) so I definitely understand not wanting to use a Heart Scale on a move a Pokemon learns by leveling up.
I erased my vote, but when I try to vote again for A, I get an error that says I have to answer every poll question, even though there's only one question now.
You don't get a badge from him. You get it from the new Poison Gym Leader later on. For the cave, from the room south of where you entered, you have to follow one of the paths all the way down (I think it was the east one) and you should reach a place with a door where a character will tell you about the cave and then you'll battle the grunts there with Victoria.
Granted. It's the only game you can play now. Trying to play anything else will give you errors.
I wish all the waiters and waitresses turned into penguins every Halloween.
You need to go to Goldenleaf. After going there (you don't have to do anything in the town, you just need to set foot there) she'll give you the Mareep when you talk to her.
IIRC, you didn't even get challenge or easy mode until post game and it didn't carry over to new files, so the only way to actually use it from the beginning was to have it sent to you by someone else which is impossible for someone like me who doesn't and can't do online or multiplayer stuff. Whatever the physical copy of the game by itself offers is all I can do. So no B2W2 keys, no trading, no Pokemon Bank, visiting Secret Bases, etc. Not that I wanted to make the game harder or easier, but it just seemed so dumb to me to not have it available from the beginning.
