I'm really getting excited for the opening!
Pleeeeease show something epic and no Charizard, which is a childhood boys wish ()
The Roserade line is so overused though for no good reason. It was Drew and Nando's main Pokémon, it was the star of a DP filler episode, Barry and Gardenia had one and it was the main Pokemon of the Mean Girls from Unova.
If we're talking about Roserade, then we can state that Roselia was not overshowcased during AG, aside from Drew, it only appeared in a couple of cameo's.
Nando's main pokemon? That's debatable, Kricketune played the pivotal roles in his later tournament fights against Zoey and Ash.
Star of a DP-filler? Okaaay... Oh.. Do you know the Poffin Plan?
Barry had one, it appeared once? It had one move.
Gardenia used one as her final pokemon, yet Turtwig was treated as her main pokemon due to Ash having it as well.
The main pokemon from the Mean Girls was Cinccino, don't forget that.. -.-
Roserade is used often, that's true, but it's not as if it's the second coming of Steelix/Scizor..
