Ok guys, the idea of an undead Pokemon is an excellent idea, but it is a little underdeveloped. My suggestions are to yes, make some kind of special animation for them. Also, I would like to mention the fact that you can cure Undead Pokemon through the use of a rare, but achievable, item. Also, there will be several Undead attacks, so that should make it a little more interesting. Also, it is quite possible that we could change the graphics for their pictures if they are Undead. Undead Pokemon are a great idea, so try not to post crushing posts lke the above ones, as these are the reason that bad things are not improved.
