I'm Lucy Liderson reporting live in town on the newest supervillain, Uraniman! Let's take a look at his evil powers!
MUAHAHAHA
Uraniman is able to stretch his own limbs to inhuman lengths due to the physical property of uranium being ductile! He is able to swing his arms around and take people out with just one swing, and is able to swing from building to building simply by grabbing it!
HAHAHA, you fools! You'll never be able to defeat me!
Uraniman is also nearly indestructible on the outside since Uranium, the metal Uraniman is based off of, has the physical property of being very dense!! He is not affected by bullets and can keep causing mayhem for hours!
However, since uranium is radioactive, Uraniman's weakness is his own self, as he decays slowly over time. Since he is now fused with the radioactive element, it is in his skin and body, and as a result it decays spontaneously. This is a chemical property of the metal.
Ouch, I'm decaying! I'm not going to be able to continue like this!
