Spider-man, AKA Peter Parker was first introduced to the public in 1962 in issue 15 of the Amazing Fantasy Comic book.
He was orphaned t a young age and so was brought up by his loving Aunt May and Uncle Ben.
By the way, did you know that Stan Lee decide to add the hyphen to Spider-man simply to save the confusion between Spiderman and Superman, as he felt they looked to alike without it!!
Peter had a fairly normal childhood and it wasn't until his teens that his live was going to take a rather dramatic turn, when as a high school student he attends a science exhibition and gets bitten by a radioactive spider, causing him to gain the extraordinary abilities and agility of a spider.
Ashort time after discovering these new abilities and talents Peter's Uncle is murdered during a burglary and in a fit of anger and rage Peter Parker avenges his death.
It is after using his new found talents and abilities for violence and evil that he begins to respect them and ultimately creates his alter ego Spider-man to fight injustice and evil wherever e finds it.
