[The Turbanator]

Zapdos. is the only one that takes 25% from Stealth Rock.

[orangeralts21]

Regirock because it is not hit SE by Fire type moves. (took me forever to figure out a difference btw)

Tangrowth, Yanmega and Mamoswine

 

[destinedjagold]

Mamoswine, because grass and flying types are weak against ice. ^^

Cobalion, Terrakion, and Virizion~

 

[Hero of Twilight]

cobalion because it is needed to catch the other two
