Along with Batgirl, the Penguin gets a new release in the Batman Unlimited line. Originally, the Penguin was released in the first wave of DCUC. At the time, I wasn't sold on the idea of collecting 6 inch DC figures, so I only bought Batman. By the time I changed my mind, Penguin was too expensive for my tastes. I figured that given the very low chance of parts reuse, there would inevitably be a re-release, although it was a big longer than I was expecting until it happened. For this release, the Penguin was repainted in a color scheme more reminiscent of his old Super Powers figure from the 80s. If I'm remembering correctly, I think that figure was repainted for the Batman Returns toy line. The other change, which I was not aware of until the figure arrived in the mail, is that he gets a completely new head sculpt. The original figure's head was a bit more monstrous, while this one is more cartoonish and cheerful. You can tell this Penguin uses a lot of bird puns. Fortunately, he also comes with an accessory, an umbrella with a machine gun attached.
Penguin commandoes work so much better with a Penguin to command them.
