"Wow, this Pokemon is more useful than I thought"

[HappyEmoKid]

Well, before i was obsessed with dragon types i was into normal types alot
so i made a team cnsisting of:

Clefable, magic guard and a flame orb and facade pwnage
Girafarig, never knew he was normal before
Blissey, is a pure spec wall
Snorelax
Ursaring
and a Togekiss

all of the above i used to think of as pretty bad.
besides Blissey and Togekiss

Yes. My beloved Wobbuffet. ; w;
I caught him waaaaaaay back in 2004 when I was younger and I never really knew anything about Wobbuffets, but when I started battling with him I was amazed. ; o;
I will never get rid of that Wobbuffet. We have a CONNECTION. xD <3

[Wings Don't Cry]

I thought Parasect was useless and then i tried it out and it was godly in GenI.

Spore, Sword's Dance and Slash will get you through nearly al your opponents for the Psychics you had Leech Life.

[Hatenko]

Electrode and Weezing. Not only are they not the worst Pokemon around with not too shabby movesets, their Explosion is very useful on PBR alongside my Mismagius ^-^

Generally though I'd choose Electrode first for two things. One, Magnet Rise + Earthquake. Two, its speed wouldn't even give the others a chance to act. Weezing's pitifully slow.

This! When I first caught Shinx I just thought it would be the 'cute' mascot of my team...and then he went on to completely own the Elite Four and Cynthia. \m/

[Dark Shade]

Wynaut. it looks like a crappy baby pokemon. Apparantly its Uber!

[Ayselipera]

I once played Sapphire and decided to use pokemon I would never catch. Sabeleye ended up being one of these and I was actually pleasantly surprised along with Hariyama too.

Sheer Cold Articuno ROCKS when you teach it Mind Reader along with Sheer Cold. Very useful, indeed. ^^

For me, the most useful pokemon that I randomly happened to find is Blissey. I just started playing around with a Blissey one day because I was bored...and it ended up being a LOT more useful than I had imagined...

[Season]

Staryu in Pearl. I caught it because I wanted a cool water Pokemon but I wasn't expecting it to do much in terms of fighting. I was totally wrong, Staryu ended up being the powerhouse of my team, it was basically unstoppable.
I stopped using it once it evolved into Starmie because it made the game too easy. I never lost with it.

[KurlyFries]

Pelipper/Relicanth in Ruby. They double as HM slaves and Groudon-catchers. Relicanth yawns, I switch into Pelipper (who resists all of groudon's moves really well for an untrained pokemon). then just spoon-feed damage to Groudon via Surf.

[DeathLucarioX]

My Togekiss....I was just catching him for fun nd decided to train him...now he kicks butt! xD

[BlaziquazaLv.Z]

Let's see...Magmortar.Saved my butt a lot.XD

[SonicThrust]

I'm sure it's already been mentioned, but I found that Shuckle can actually be useful and annoying if used properly.

[Niprop]

At first, I thought using Dunsparce as my main partner would be heck (like training an Eevee). But it turned out that he was actually easier to EV train and level then most legendaries. Even at level 12, he didn't faint to Wingull's Pursuit at level 51, and even super-effective attacks from pokes twice his level wouldn't KO him. Not only that, but Glare + Serene Grace Headbutt or Rock Slide reduces his chances of being hit and makes him actually very fun to use. Dunsparce (for the record, I named mine Duncy!) may not be the smartest, or strongest, or fastest pokémon around, but it's his modesty and charm that sets him apart.

[Asian Pride]

I didn't think that Shuckles could've taken a Hyper Beam from a Dragonite before. Well, that was until I had it fought Lance with my Suicune.

[Aljam]

When I discovered the wonders of wrap in RBY ^_^

[Ninja Caterpie]

Magikarp.

You have no idea how awesome I felt after sweeping a proper competitive team with a Magikarp's Flail set up by a Smeargle.

[brendonb]

my golduck helped me beat the electriv gym leader in pearl after my starter fainted

[Ontop]

Hariyma back in R/S/E. I just cought it for fun and started lvling it. A time later is my strongest pokémon.

[Armoire of Invincibility]

Bibarel, Rapidash and Luxray

I used all three for the first time ever on Platinum and was absolutely shocked.

Bibarel had nothing but HMs, but still managed to demolish most things and soaked up hits like a sponge. Both Rapidash and Luxray were pretty fragile, but surprisingly fast and powerful. Rapidash completely swept Byron for me.

[Pekin]

I'm gonna go with Breloom - I'm currently doing the ultimate monotype challenge with the Grass-type, and Breloom has saved my ass several times by now. For instance, when I battled Winona, he actually took out most of her team after two or three members of my team had already fainted, despite having a 4x weakness to Flying. Seriously, the thing is a beast.

[friendly_trainer]

say all the things but metagroos is the best

[MithosFall]

I haven't but my friend has. I asked him what pokemon he would put in a team from all regions. And for his second one he said Dunsparce!

[Polizard]

Ambipom i was just training it originally just to get some items from pickup but he is actually a good fighter

[Mutt19]

My answer to this is Machoke
