Magikarp because all it can do is use splash(which does nothing), Metapod can at least try to protect itself.
It is not the unown who named them must have been a dyslexic researcher who named them. I like the unowns because theyre cute (i also have 98 % of the TCG cards too ^^) but its soooo useless .I'm going with Unown. It's the only one of those who tries to be special and just fails. The rest have somewhat interesting designs, but Unown is based of (usually illegible) letters, trying to take a stab at the whole "mysterious" scene. To top it all off, it's hard to believe that, despite being made of letters, is dyslexic. It's Unknown, for Arceus' sake.
Dunsparce is just plain awesome. Serene Grace and Ancientpower abuse is a thing of beauty.
Why did I include Dunsparce?? I didn't! People of this forum nominated him! I didn't just decide to add any Pokemon I deemed as useless.Unown sucks. Dunsparce can flinch you to death. Why did you include Dunsparce and why not Silcoon, Cascoon, Kakuna, or even Luvdisc, which has poor stats except Speed.
Magikarp can kill you if it recieved a Belly Drum, holds a Focus Sash, is EV trained (252 atk and spd), and uses Flail.
