What are your favorite pokemon to use in battle? What pokemon do you believe to be the most annoying to fight against? Favorites: Dragonite - Tanky and powerful. Greninja - Extremely versatile sweeper. Aegislash - Saved my ass on so many occasions. Probably my favorite pokemon right now. Most annoying: Darkrai - Damn you, Dark Void! Rotom Wash - I hate this -blam!-er. I can never seem to kill him. Mawile, or pretty much any other Fairy type - I have no real counter. Only Aegislash. You, Flood?
