What would a Spider-man / Batman mashup comic be like?
This picture I spotted on Crawl Space, of the Spider-man rogues mixed with Batman villains, got me thinking:
We've already had a couple crossovers with Spider-man and Batman, and there was even a mashup with Superboy (to make Spider-boy, naturally) for the Marvel / DC Amalgam event.
But what would a story featuring the combination of elements from both Spider-man and Batman be like? In particular, how would the main character be? Peter Wayne? Bruce Parker? There's the connection that both lost parents or loved ones to violent crime. There's the similarity that they both adopted animal personas to fight crime. But what would such a thing be called? Spider-bat? Bat-Spider?
