I would choose:
Torchic
Dratini
Larvitar
Ralts
Squirtle
Cyndaquil

If I started with only 6, my choices are

Tyrogue ->(Hitmonlee).....because Hitmonlee can learn Blaze Kick, Low Kick, Bounce, Revenge
Piplup ->(Empoleon).....Brine, Steel Wing or Flash Cannon, Avalanche, Pluck
Meditite ->(Medicham).....Psycho Cut, Thunder Punch, Fire Punch, Ice Punch
Happiny ->(Blissey).....Grass Knot, Drain Punch, Return, Copy Cat
Gible ->(Garchomp).....Dragon Rush, Earthquake, Shadow Claw, Sword Dance
Skorupi ->(Drapion).....Cross Poison, X-Scissor, Night Slash, Stone Edge

With a team like this you could pulverize about anyone.
Though I have not tried it

-Dratini
-Zubat
-Poliwag
-Abra
-Tauros
-Treecko

My fav starters

No, ,I won't put up with your ****.

Mine would be:
> always Female! (Refer back to my name- I always name Female Torchics Torchie) My favorite of all 493+!
> My LG starter and my second favorite Water Type ( is my favorite water, but I'm not choosing that one today)
> I finally got one in Diamond byTrophy Garden, and well, I just got it for data. I'm breeding more Eevees from her and hopefully get Wish+Curse Eevees. Anyway, she's better than Alakazam, both in looks and movepools. She can learn Grass Knot (which my brother taught her), Thunderbolt, Thunder Wave, a lot of other Electric Moves, Psychic (duh!), Shadow Ball, CM, DT, Last Resort (although that's not my favorite move), you name it! Oh, BP, Future Sight, Morning Sun, Curse (egg-but why would it? Maybe for an Umbreon), yeah. I'm getting too long.
> I love Jolteon! The one in Emerald (refer to my sig) is awesome, even though I still have Bite with him. He's a Calm Nature, but kicks Pheobe's 's butt like crazy with one Bite. I guess I can because it's Lv. 89, but still, I think it's got lkie zero IVs in Atk. Ah well, I need more coins to get a Shadow Ball for him.
> I was going to say , which is my favorite Dragon+legendary Pokemon ever, but since you don't allow legends here, it'd be Altaria, since mine saved my butt every time in gym leader rebattles, not including roxanne.
And finally...
because of my Lonely Nature in Emerald. She's like awesome with attack, as I'm pretty sure she's got 31 Atk. IVs and definitely 252 EVs. She knows Crush Claw, the ultimate Normal move (for me), Thunder (since I'm done with Lucy, I'm getting Slash or False Swipe back), Swords Dance (max that attack!), and Taunt (for Lucy and just to annoy those walls and BPers)
So yeah, here's my 6.

--- protect, double team, slash, night slash ---- adamant
--- lava plum, headbutt, extra sensory, agility - bold
--- sleep powder, petal dance, teeter dance, synthesis- modest
--- secret power, ice fang, bite, dragon dance--- careful
--- thunderwave, brave bird, night slash, screech--- impish
--- power trick, cross poison, U-turn, stone edge--- careful

Ralts
Buneary
Eevee - Glaceon
Snorunt - Female
Duskull
Oddish - Bellossom

I do so enjoy a challenge.

why frankly I'd try to star out with some of the stuff that evolves in to my faves for for my handy dandy Sub puncher Substitute Focus Punch Earthquake Ice Punch
for what else for the final set but but Air Slash Shadow Ball Roost and Aura Sphere
for makes a nice rain dance staller or sweeper Rain Dance, and Surf, for sure. Leech Seed and Giga drain for Rain Dish but if it has Swift Swim Energy Ball and Ice Beam work
and it's line always come in handy Final set as lanturn Ice beam T-wave
T-bolt Surf
final set Fire punch wish Iron head body slam hey it is a very amazing pokemon pardon that it is a legendary but i can't think of any thing better.
I personally like heracross So I have a status absorber
Final set Sleep talk rock slide megahorn and close combat because of the type coverage and ability to absorb status And and still have a great move set. and the Insane defensive type coverage I'd have at the end of it.

Just so you know, I know and would be good options also but I dont use them so I can Absorb status mainly sleep

for later blaze kick/sky uppercut/earthquake/return
for later surf/ice beam/darkpulse/hiddenpower
now that i got my 2 killing duo, time for pokemon that can learn lots of hm
and godsent hm users
then i'll have for softboiled, healing my pokemon on the way
and last i prefer to use dig and flash
okay now im ready for any adventures

I once made a few modifications to begin the game with a Dusknoir because I love them. O_O

I love Dragon types so I say,

Bagon for Salamence: could kill any type with Dragon Pulse, Earthquake, Fly and Flamethrower.
Swablu for Altaria: could kill many types with Fly, Sky Attack, Dragon Dance and Dragon Pulse.
Feebas for Milotic (that snake somehow looks like a dragon so I'm choosing him instead of a Gyarados=overused): could kill many types with Waterfall, Ice Beam, Dragon Pulse and Hydro Pump.
Trapinch for Flygon: could kill many types with Earthquake, Rock Slide, Dragon Claw and Strength.
Gible for Garchomp: could kill many types with Earthquake, Rock Slide, Dragon Rush and Rock Climb.
Horsea for Seadra: could kill any type with Ice Beam, Surf, Dragon Dance, Dragon Pulse.

k mine is

my favorite Pokemon ever
my first ever starter
y because it was main Pokemon in Pokemon ruby
why because its cute
umm well i love this Pokemon
or pikachu i just love pichus looks

I would go with

because it was my favorite kanto starter
'cause that is an amazing type combo, and it never bets to double up on water types for HMs
because sure, it takes a lot of effort to get there, but salamence is beast
for evolution because steel is awesome
because it is also awesome
because I said so

It's a tough decision for me, but I decided on:
Darkrai
Deoxys
Ghastly (Gengar is the greatest, you can't deny it!)
Torchic
Raquaza
and finally, Ryhorn.

blissey (my fav, which i recived as an egg, but when i start my adventure it would would be a blissey)
torchic (which later evolves to blaziken, cause he is my sacond fav)
munclax (which doesnt evolve)
zubat(which later later evolves to crobat)
eevee (which will later evolve to umbreon)
mareep (which later evovles to ampharos)

the cutest AND the strongest starter ever!
Garchomp is my favourite pseudo legendary.
just to annoy my friends in wireless battles.
looks awesome and BOOOOYWEEEEOOOOO!
Flygon isn't as strong as other dragon types but has the coolest eyes ever.
I just love gardevoir, it's one of my favourite pokemon.

(by the way that wierd boyeewoo thing for togepi was supposed to be togekiss' cry )

* 4 Years Later *

How lame..


What I will start with:
---->
---->
---->
---->
---->
Undecided.
---->

Probably Riolu, Bagon, Aipom, Elekid, Feebas (I like Milotic!) and Cyndaquil.

This is the pokes I would want to start with

Then they will evolve

And that was hard to decide

Beldum
Gible
Ralts --> Gallade
Charmander
Carvanha
Pikachu

If I could start with anything...

PONYTA

AZURIL {azuril}

AIPOM

GLIGAR

KRICKETOT

WEEDLE

Most of my fav pokes. Weedle is the only one not on my favs, but it gives pretty good coverage. When theyre fully evolved, they have these types:

Fire

Water

Normal

Ground

Flying

Bug

Poison

7 types! So, pretty nice.

Changed my mind:
(male)
