The worst pokemon in the world...

[FourCartridge]

Without going to what has been said a billion times on this topic, Bidoof and Bibarel.

Dunsparce for me was useless
also what is it?

 

[Misheard Whisper]

Oh yeah, Unown. Gah. Not only are they useless in battle, but they look stupid and they're essentially the most pointless of pointless sidequests.

 

[Aura Rift]

Uknown is by far the most useless Pokemon

 

[Rionix]

I don't like Unowns.. And yeah, I don't like them cause they're pretty much useless, they're just there for collection purposes but I don't even want to collect them.

Magikarp. Or Unown. Depends on what level it is.

 

[SuperSaiyanII]

Well, I hate Patrat and Watchog with a passion but the most useless Pokemon by far is Unown. At least Magikarp evolves on level 20 and even if it doesn't, it still learns one more damaging move than Unown does.

 

[Charizard★]

Feebas and Magikarp get my vote. They don't learn any good moves and they're just literally useless :x

Dunsparce & Qwilifish are easily forgettable & completely useless for and to me.
