Spiderman

The spider-man had to defeat his old friend Henry who has become super villain by taking injection of spider poison. The spider-man had to defeat Henry or otherwise. The whole of America would be destroyed. Henry thinks he could easily kill Spider-Man. 

But he was wrong as he didn't know how to use his power and by mistake he killed his father and now the whole public wants to make Henry died. He begged in front of everyone of public. But they didn't agree to spare him. Then the spider man said that everyone should get at least one chance to prove himself. 

So, from that day he stopped hurting other and with the help of a scientist. He removed his power and become a normal human being.
