I was shopping at Target when I saw another set of blind packaged Marvel superhero figures. These are called Marvel 500. Why are they called Marvel 500? I have no idea. These are pretty basic pvc figures, a little over one inch in height. The set at Target was Series 1 but I looked on eBay, it looks like there is always a series 2 out. Series one has a regular green Hulk and a translucent Hulk. The second series has a grey Hulk and even cooler, a Planet Hulk figure. There was a Red Hulk in the first series but I decided not to get it. Pretty neat and affordable, I hope they continue the line and have more variations of the Hulk.
