One of the things I love about Plastic Man is how creative he can get with his shape-shifting abilities. From JLA, here are just a few examples. We have Plastic Man turning into:
1) A spring (with suction cup)
2) A suitcase
3) A ladder
4) A globe
5 & 6) A football and trampoline
And my personal favorite:
7) Plastic Man with an umbrella. I have no idea why this is my favorite, but I just love the image. I think it’s the pose.
