ITT You tell the above poster why their favorite Pokemon sucks.

[Lone_Garurumon]

Merciless is a great ability on paper, but Toxapex's defensive playstyle doesn't really mesh with it too well.

Golurk

 

[Max1996]

It's, uh...a golem?

Mega Sceptile.

 

[~Smugleaf~]

It has one of the worst mega evolution designs I've ever seen. Looks so awkward.

Incineroar

 

[MegaPod]

Looks like someone force fed poor Litten steroids. And a belly button flamethrower, seriously?

It's a walking tower of bricks. That's just weird.

Riolu.

 

[Lone_Garurumon]

It's not a Lucario yet.

Arcanine.

 

[MegaPod]

"The Legendary Pokémon?" False advertising.

Crumbles at the sight of a Fire-type

Zekrom

Not as good as Reshiram

I don't think it can see all that well with gems covering its eyes.

Its brain is located in its rear.

Klefki

 

[~Smugleaf~]

Has a very boring, uninspired design.

Wailord

 

[Wispy Willow]

It's secretly a balloon.

Pidgeot

 

[~Smugleaf~]

Has an ugly shiny.

Virizion

 

[Lone_Garurumon]

TPCI insists on pronouncing its name like idiots.

Aegislash

 

[Max1996]

It has Attack and Defense forms.

Umbreon.

It sprays poisonous sweat from its pores. Ew.

Cryogonal!
