The Clown Prince of Crime
Super Freak
What other material could be used to recreate a Batsuit? I personally love the one used on the EB Bats.
Good old fashioned hard plastic like the Predator figures or the 1/4 neca 89 batman. After all, he wears armor in the film, so it might be a good choice, imo. The head sculpt is hard plastic already. You can always trust hard plastic.
