Counterpoint: DC does not currently have a character that acts anything like Dress Horse. It would be something unique for Zatanna if she staked out that terrain.
But more seriously, this show's Zatanna is great because she's got several extremely potent personality traits that always factor in to how she acts in any given storyline. Can you say that about comics Zatanna?
'Member the Plinkett Test? "Describe a character without mentioning what they look like, what they can do, what their function is in the plot, and what their relationship status is." It's extremely easy to do that for this show's Zatanna. Can you do it for standard comics Zatanna?
