4th Gen Most annoying wild Pokemon?

Zubat, no doubt.
In the sea, I think is obvious that is T-Cool.

Mantyke.

A catch rate of 25?!!? FOR A BABY?!?!

While Surfing : Magikarp or Tentacool
Land: Zubat/Golbat or Geodude/Graveler and maybe Ratata/Raticate :(

I HATE Bronzor with a passion! D: And of course the usual Zubats, anything that traps you, etc.

Zubat and friends the Tenta-cool or cruel they are really annoying >:(

Magikarp and zigzagoon, those are the worst

Pidgey, Ratata, Bidoof and Starly. I should say their whole evolution line because you can find them in the wild as well.. Not all of them but you get the point! :P

(Sorry if this counts as a bump D: )

I hate running into Geodude and Tentacool. Otherwise I don't really get annoyed by any of the other common Pokemon.

I actually really like Zubat so I don't mind running into them. lol

Diamond/Pearl water routes were sooo slow, so whatever common pokemon they had in water (tentacool?) would be the most annoying. Tentacools in HGSS.

It's gotta be Rattata. Every time I was in the grass, I ended encountering them in almost every step. I've had to spend tons of money on Repels just to get away from them, haha. Due to the same reason, Zubat and Tentacool were quite annoying as well. Plus, it was quite hard to defeat them if your Pokémon were under level 10, because they had a tendency to confuse you a lot with Supersonic. D:

Definitely those Graveler/Geodudes, each time I try to kill them for Exp they survive and then use self destruct, and the only one that can survive it is my Quagsire cause of it's defense.
