Now, I don't think I should post on a topic this old but...this may be helpful.
If you mean have the enemy character animated, just make individual skills for him, and in those skills, set make the animations the hero's movements. When the enemy uses those skills, he'll/she'll seem to move.
Just make sure you erase the actual enemy using the appropriate piece of background in the right place, or the enemy'll still appear during his own attack.
