Hmmm... I'm making a list of avalible pokemon up to this point in the hack, and here's what I have:
RATATTA (Raticate) - Starter, Route east of Safaron
VULPIX (Ninetails not avalible) - Choice of Vulpix, Poliwag, or Oddish in Safaron
POLIWAG (Poliwhirl, but Poliwrath and Politoad not avalible) - Choice of Vulpix, Poliwag, or Oddish in Safaron
ODDISH (Gloom, but Vileplume not avalible) - Choice of Vulpix, Poliwag, or Oddish in Safaron
GASTLY (Haunter, but Gengar not avalible) - Pokemon Tower
ZUBAT (Golbat, but Crobat not avalible) - Pokemon Tower
CUBONE (Marowak) - Pokemon Tower
PIDGEY (Pidgeotto, Pidgeot) - Route east of Safaron.
I think that's all. Any others?
EDIT: Well, I finished the Alpha, and will not pick up the game until Alpha 2/Beta 1. This is my team.
THE CRIME LORDS:
Vermin the Rattata - level 16, Hyper Fang, Quick Attack, Tackle, Tail Whip (Run away)
Rattata's cheezily powerful Hyper Fang made it one of the best pokemon in ingame FR, and while I didn't get to Hyper Fang until I fought every trainer, Vermin will remain on my team. He actually was the cornerstone for designing my team (Vermin, Kitsune, and a random Water type), and I was happy to have it along.
Kitsune the Vulpix - level 16, Ember, Quick Attack, Roar, Tail Whip (Flash Fire)
Vulpix is easily the best pick of the three, as it is the one that can best combat Gastlys in Pokemon Tower. It served me much better than Vermin in this Alpha, and was a pivital force against many of the trainers. It was also my first pokemon past level 15.
THE GOONS (I just leveled them up out of boredom)
Pidgey (level 10) - Gust, Tackle, Sand attack
Gastly (level 10) - Lick, Hypnosis, Spite
Zubat (level 10) - Astonish, Leech Life
Cubone (level 10) - Bone Club, Tail Whip, Growl.
Meh. Random goons. I admit, Gastly was useful, and I almost put Cubone on my team, but they will rot in the box until (and if) I decide to evolve them.
