My most feared pokemon...
When 5 out of your 6 pokemon are weak to Bug, this guy is a problem. I added a flying type to my team just so I wouldn't die to this.
Only if my Starmie is dead when it comes out.
His mustache scres me...
One of my best pokes cant hit it. 2 others die explosively to it.
Most dark types scare me also.

Celebi. My friend had one that knew perish song, and the only thing that could counter it was my Mewtwo that knew fire blast.

No Pokemon Fear me

But any one that constanley parlazies or confuses or poisons my Pokemon is extremly annoying.
Ekans, Pikachu and Zubat spring to mind.

and Weedle I hate them!!!!!!!

STEEL POKEMON OMG DX

I just fought Byron and it took ages to kill off his Pokemon. One of them knocked itself out with Struggle. I don't remember what the Pokemon was called though. It was the level 39 one. That's what I fear. Having battles come down to Struggle DX

It was a Lv 39 Bastodion

The Salamence in the Hoenn Elite 4- When I first played Ruby it took me about 6 trys to beat it.

I really really don't like Garchomps... Whenever I see one in the battle tower, they're usually super fast and deadly. Even though I have some EV trained pokemon for speed, and battle tower pokemon usually aren't EV trained, Garchomps usually get to go first anyway. Like seriously, a fully speed EV trained Kabutops with rain dance and swift swim usually is out done by any ol' Garchomp...

Personally I fear any pokemon that dragon and contain Ice, or Electric type moves because thats almost always the end of me in online Pokemon matches. Also, I hate people with Blissey which they just use to make you waste all your good pokemon and moves on KO-ing it.

*Gulp* ...... Garchomp... Gulp..

creepy!

i feared rotom in the battle tower because i had nothing that could hit it (bronzong, uxie, lucario) i could not faint it.

Pokemon I fear in a battle is Alakazam only because I know he can be deadly and I have little experience dealing with it.

my friend's arceus..........

Didn't see anyone who said this, I'm surprised. One Pokemon and one Pokemon only: Smeargle. Hmm, lets Spore and then God knows what he'll do next. Damn exploding dog... *grumble.*

There is nothing worse than thinking you've won then having your friend pull out Arceus and destroy you. God I hate that thing.

Also, Garchomp and Blissey make me cry a little bit when I see them.

One word.

The most demonic Pokemon of all, scarier than Houndoom itself.

Shuckle.

Garchomp is nothing compared to this (Ice moves very useful) sinceyou can't hurt Shuckle. It is nigh invincible and if it has power trick, say bye bye.

Any pkmn which is strong in speed, offensive and defensive moves. Oh yes, and HP as well......

Not to say I fear them, but those Pokemon with extremely high speed, HP, defense/special defense always annoy me.
Oh, and also . Destiny Bond + Mirror Coat + Shadow Tag ability + Extremely high HP = WHAT A PAIN!

Any fast fire pokemon
My team have a weakness to fire now

Two of them.

Breloom. Urgh... with Leech Seed and Poison Heal helping it recover behind a Substitute before it unleashes Focus Punch, it is hard to take down unless you have a fast Pokemon that can OHKO it out when it's sent out. Plus, they often carry Spore.

Blissey. Almost impossible to take down with sky-high HP and Softboiled. Probably even more annoying than Breloom.

OMG with the set. My bro has the same set. I really hate it now.

Also, any toxitrapper can be really REALLY annoying...

I suppose the pokemon that brings back worst nightmares was Lapras, due to defeats suffered all those years ago in Blue and Red.

The one Pokemon I fear to battle is Magikarp - it is a double-edged sword, if you lose, you lost to a Magikarp, if you win, so what? You beat a Pokemon that knows slash and tackle and won minimal EXP.

I also hated the Fury Cutting super-fast Scyther from GSC, second gym.

I would have to say Weezing. Outside of battle, it uses destiny bond on my lvl.100 Rayquaza(because I use fly to avoid them if they use explosion)and takes me down with it. *shudder*
