I bumped into these collectibles of Penguin and Catwoman on the NECA Toys website. Because they say they're discontinued, I assume that they're rare to find and buy online. Shame, because the designs look great.

Really admire them for doing a angry sewer onesie version too, very brave.
Holeeee sheeeeit. I decided for kicks 'n giggles to Ebay these to see how much they might be.
I think I will be sticking to my Kenner action figure from now to eternity lol.
