I use to think Palkia was the strongest pokemon ever

[XLugiaReshX]

Yea but stat wise Mewtwo is better

 

[~Light]

I used to think that Mewtwo was the strongest Pokémon ever

Just because he was the strongest legendary you could catch in the first games

I thought that surskit was a 'super ultra lengenary'. That was before I stopped randomly reading only parts of the dialoge. When the guy in Ruby said, "There is a lengendary pokemon!" I freaked out.

(topic title), but then I took an arrow to the knee.

If we're talking about legendaries that we thought were good but were disappointed about later on, I have three.
Kyurem, Cresselia, Regigigas.
Each for obvious reasons.

Back in R/B/Y days I thought Alakazam was amazing....then I met Mewtwo

Ahhhh psychic's.....only super-effectively damaged by the few bug moves that existed back then.

 

[ToeyJoey]

Alakazam was still amazing back then though.

 

[Frozen Sunset]

Of course, he was incredibly tough (thus why I thought he was the strongest for a short time).

 

[Mr. Reloaded]

Though I though Mewtwo was the best because I honestly thought he'd be as strong as he is in the movies which isn't the case mewtwo is strong but after Gen III came around several Legendaries took his place as king.

 

[Demonsead]

Mewtwo, partly because of the anime.

 

[ThisIsPatrick]

I had Mewtwo and it swept the E4 like 80 times on its own in Lg. I bragged to my friends about it until my friend versed me with his Lv 100 Rayquaza. And lets just say for the record i only lost because Mewtwo was confused!

kyogre isn't fast enough...if equipped with wise glasses, specs, or life orb, two thunderbolts/ thunders from mewtwo (assuming no calm mind boosts) will get rid of kyogre or it could use psybreak, grass knot, energy ball, etc....kyogre's only hope against mewtwo is to be scarfed and lead with water spout but that's very predictable and can easily be stopped by any water absorb/ storm drain pokemon (like lapras) or hope that hydro pump hits (one surf isn't taking down mewtwo)...without its water moves, kyogre isn't so scary in th ubers tier...mewtwo, however, is a lot more versatile and can function perfectly well without psychic moves, it can be a supporter, it's just so much more dangerous and unpredictable than a kyogre...

You've got to remember that when deciding which pokemon is better, seeing how they'd fare against each other isn't always the best way. Shedinja can pretty much always beat Kyogre one on one, but to say shedinja is better then kyogre because of this would be foolish.

 

[Zoruagible]

Victini is my strongest right now.

 

[Wyrm]

After leveling Sceptile in my first Emerald playthrough to the maximum, I thought it could destroy all the Legendaries at once. But then I met Serebii.net... Oh, and took a double-edged axe to the shoulder.

 

[Pokemon Whisperer Natural Harmonia Gropius]

I used to think Mewtwo was the strongest, but in some ways he is the strongest.

 

[salaswampert]

When I was younger I thought event only pokemon where the strongest, I didn't realize they all have 100 base stats across the board.

 

[Wolf Prince]

I wish I grew up with 1st gen sometimes. Instead, I used to think that Rayquaza was the ultimate. Looking back, I really wasn't that far off.

my first gen was gen 3 and i too thought Rayquaza was the strongest, until i heard some spoilers on the internet about the new D/p/p having a god pokemon.

 

[Flame Mistress]

I used to think that Torterra was the strongest Pokémon. Not Dialga, not Palkia, not even Giratina, but Torterra. That out of all things... >.<

 

[ToeyJoey]

Don't knock Big-T, his Rock Poish set beats... Golem and... Rhydon...

 

[Atratus]

I used to think Dragonite was the strongest pokemon, but then I got an arrow to the knee. Oh Arceus, I am saying this and I never even played Skyrim.

But with all seriousness, I did. I remember when playing R/B/Y and G/S/C, Dragonite always seemed so powerful under Lance's care. With the hyper beam mechanics back then and me using mostly fire/water/grass typed pokemon, it was a true challenge.

 

[Hendoukje]

I thought the Regi-trio was really strong, mainly because of their looks. Every time I used them I hardly stood a chance, though.
