Spider man used to be my superhero as a kid
Used to be? Not anymore? Haha. Spiderman is a fictional superhero made famous my Marvel Comics with all his comic books. 
Sure! I'm no longer a kid! Now an adult with better preference, hope you understand? Well who invented the character?
The inventors are Steve Ditko and Stan Lee and Spiderman was first debuted in 1962.  
What's the name of the spiderman character when In human form?
His name was Peter Parker and he was being raised by his aunt and uncle in New York. His real parents were killed in a plane crash! What a story line! 
Uhmnnn! That good ! So what other stuff does spiderman do?
Well in the Peter Parker form the story line had him dealing with the struggles of adolescence and financial issues. I don't really remember that, lol.
I got my kids a spiderman costume! Isn't that wonderful?
That is fun! Peter Parker became Spiderman because he was bitten by a radioactive spider that gave him superpowers!
