Most Temperamental Pokemon? (By looks only)

I would have to go with Electabuzz, as it always looks like its angry with its "V" shaped marking on its forehead. Even in the anime, Electabuzz was always screaming and looked like it was going to electrocute anything and everything it made eye contact with.

I mean, just look at Paul's Electabuzz...

Spoiler

Someone isn't a happy camper.

 

Well, Gyarados is a dead giveaway here... I mean if we're talking about angry Pokémon, Gyarados obviously is the first one to come to my mind...

Though Victreebel doesn't look too happy either... [3D=victreebel]

 

Garchomp always looked kind of intimidating to me. [3D='garchomp']

I love Zangoose but IMO he looks angry all the time. Even in Pokémon-amie. [3D='zangoose'] Also he looks like his paws are soaked in blood.

 

Purugly always looks so grouchy. [3D='purugly']
There's also primeape who just looks like he's really to sock you.
There's a lot of angry looking Pokémon, and Gyrados is for sure on that list.

 

Snubbull looks pissed off all the time

 

Weavile looks like it's going to slash you to death with its claws.

 

Tyranitar.

It looks like it's making sure you do nothing wrong, and if you do, it'll go berserk. It's Pokédex entries state how it can level entire mountains, and how it's pretty much evil. Definitely not something you'd want to anger.

 

Probably Primeape or Tauros. Granbull and Weavile are some others.

 

[3d=emboar] I feel like you could make it mad quite easily (although I don't think you would want to make it mad xD)

 

[3D='zapdos']

Zapdos definitely needs some consideration. I mean, look at it. It's got a bunch of angle-y lines and shapes that comprise its face and body, which show you that it's not something you should mess with.

 

[3D='zebstrika']

It always looks mad, like it wants to shock you and then trample all over you.
