I was very surprised at who drew this. And I'm pretty good at identifying artists by recognizing their style. A different inker can make a big difference.
The above is some of the very first pro work of this guy:
Todd McFarlane. His style sure changed a lot. (Of course, there's the difference in inker, too. Vince Colletta's inking style is pretty much the opposite of McFarlane's.)
It's weird to me how despite his involvement in it, the Spawn animated series was way different in tone to the comics. Though I suppose if it wasn't he wouldn't had the chance to do those intros to the episodes.
