I also prefer Zoroark to Lucario, but I don't think the fans really latched onto her as much as they were hoping. I'm not expecting her to be popping up in the next Smash Brothers as Lucario's replacement like so many of us claimed when Gen 5 was first being leaked.
I think the main problem was that it was treated like an event legendary when it wasnt. Making it so you needed another event pokemon to get it in the original B/W and the only way to get it in B/W2 by another(though in game) event meant that not many people could actually get it. :/ --- Ryuho, Playing Tales of Graces F Forever in my heart.
