Horsea evolves into Seadra, not Seaking.
Also, once I've received PMs from everyone alive, I'll post a full list of Night happenings from Night 1 to Night 4.
Please give me something to write about other than Dragon Rage, it's boring.

Shellder, Cloyster, Seel and Dewgong all learnt Aurora Beam in RB, and Vaporeon in Yellow. Articuno has never been able to learn it, I think. Just to clear that up.
Actually, having 45+ Hp IMO wouldn't be all that shocking, and probably wouldn't make someone all that strong. It would probably just be a pokemon that has only two stages of evolution, of which we have seen a few already (Ratatta, Diglett, Jigglypuff, Growlithe, and Vulpix.) I wouldn't be surprised to see an Ekans, Pikachu, Sandshrew, or something of the like out there that had a slightly stronger starting form than some of the pokemon with three evolutions. In fact I wouldn't be surprised if we even had some no-evolution pokemon like Scyther, Chansey, or Lapras.
I'd be quite scared if some of these pokemon were running around however.
I'd say the Pokemon that I'm most scared of, would be a Dratini/Dragonair/Dragonite, a Gyrados (although the magikarp would be pathetic. If it gets caught and rare candied, we're in for it.) Starmie has some potential, although IIRC it requires a water stone, and Gengar or really any of the ghost pokemon would be terrifying.
It will be fun to see the end of this game if we manage to get some powerhouse pokemon going around

Matty, I could have high HP, or I could be a trainer!
I'm in teh training groundz, catchin' ur pokemonz! LOL!
But seriously, nobody is going to want to catch me now that I have taken so much damage. I dont think you have taken much, if any, which makes you a prime target for catching OR it could be because you are already caught, therefor there are less pokemon to attack you.
I shall go with random..
Vote: Tom , air/wind/tornado
Whichever is appropriate.

I haven't received lists from everyone!
However...
A Thunder Stone and a Water Stone were bought from the PokeMart. As a result, two Pokemon have evolved.
Oh yeah, Ryguy could be a trainer. >_<
To be honest, I'm actually disappointed not to have been caught by now, I'm such a lovable pokemon
unvote: ryguy, unvote type: dragon
Type: Grass
I just aint sure bout Ryguy no more, as for unvoting dragon, I'm just letting Cyclone have some fun
Ach nein! We got two evolved pokemon wandering about the place now. Perhaps some Eeveelutions or others. (I've completely forgotten which pokemon evolves from what stone, so someone help me out there)
PS. My post count is falling pretty rapidly, starting to make me look noobish.
Since we are just lyncing random people

DEATH FROM AVOBE!
Thunder Stone could be Eevee or Pikachu. I think those are the only two that use that stone. As for Water Stone, it could be Eevee, Poliwag (I think), Shellder, and Starmie.
But yeah, any of those possibilities are bad...
Fire Stone -- Growlithe into Arcanine, Vulpix into Ninetales, Eevee into Flareon.
Thunder Stone -- Pikachu into Raichu, Eevee into Jolteon.
Water Stone -- Eevee into Vaporeon, Poliwhirl into Poliwrath, Shellder into Cloyster, Staryu into Starmie.
Leaf Stone -- Exeggcute into Exeggutor, Gloom into Vileplume, Weepinbell into Victreebel.
Moon Stone -- Clefairy into Clefable, Jigglypuff into Wigglytuff, Nidorin(a/o) into Nido (queen/king).
These are the pokemon that evolve by stone in first gen, so we have either a Vaporeon, Poliwrath, Cloyster, or Starmie running around, as well as a Jolteon or Raichu. Either way it's going, this is getting scary

Vote: Ryguy/Ground
After consideration, ground seems to be a safe attacking type. Only Flying pokemon are immune to it, and only Grass resist it. IIRC, all the grass in RBY pokemon are grass/poison, negating the resistance (poison is weak to ground).
