In the world of comic books superheroes, the market is very obviously dominated by Marvel and DC. With so many heroes and villains being introduced to us over the years, many fans have started to point out similarities between the two universes. Who hasn't noticed that DC's Deathstroke and Marvel's Deadpool are essentially the same character, or that Aquaman and Namor both have the burden of Atlantis on their shoulders?
When discussing similarities between the two comic universes, one of the obvious ones seems to be DC's Batman and Marvel's Iron Man. The title of genius billionaire playboy philanthropist fits them both perfectly, and they are both known to fight crime with a variety of different high-tech gadgets.
However, gadgets aside, I've noticed that Peter Parker is closer to the character of Bruce Wayne than Tony Stark will ever be, because of these simple reasons:
Unlike Tony Stark, who lost his parents in his late teens, Peter Parker was raised without his parents from a young age, just like Bruce Wayne. After countless origin stories, I'm sure we all know about the tragic story of Thomas and Martha Wayne, who were shot down by a thug who was robbing them after a trip to the theater. The murderer fled, leaving a young Bruce Wayne to mourn his newly-deceased parents.
Richard and Mary Parker also died when Peter was just a young boy. However, they died in a plane accident. That doesn't necessarily mean that it wasn't murder though. As we see at the beginning of The Amazing Spider-Man 2, Richard and Mary were attacked in a plane, and the plane went down during the battle.
When both Bruce Wayne and Peter Parker started their lives of super-heroism, they adopted the symbol of a terrifying creature to represent themselves. Peter chose the spider for very obvious reasons. He was bitten by a radioactive spider in his teenage years, and from then on he adopted the strength and abilities of a spider. Only fitting that he should identify with one.
Bruce Wayne had a rather traumatizing event with bats at a young age, causing a fear of them that followed him for years. However, once he started his career as a vigilante crime-fighter, he used the bat as a symbol to strike that very same fear into his enemies. He dresses in all black, wore a cowl with pointed ears, and used a wing-shaped cape that he used to descend onto his victims.
When you think Thor, you think Loki. If you think Superman, you think Lex Luthor. However, if you think Spider-Man, you'll have a much longer list. If you want main villains, you'll have to decide between Venom, Green Goblin, and Doctor Octopus. But then you also have to consider Electro, Sandman, Kraven the Hunter, Mysterio, Vulture, Carnage, Hobgoblin, Rhino, and many, many more.
If you think Spider-Man has a lot of villains, then you are in for quite the trip when coming to Batman. Of course you have the Joker and Harley Quinn. And who doesn't know Bane and Two-Face? Well then you have Scarecrow, Mr. Freeze, the Penguin, Poison Ivy, Killer Croc, the Riddler, Solomon Grundy, Black Mask, Ra's Al Ghul, Mad Hatter, and at least a dozen more!
Yes, it was said that both Bruce and Peter lost their parents at a young age, but what really hit home for us were the moments where both heroes had to say good-bye to true love.
Bruce Wayne was friends with Rachel Dawes since they were kids, and as they both grew up, they only grew closer. They almost began a romantic relationship, but Rachel couldn't stand in the way of Bruce being the Batman. Unfortunately, in The Dark Knight, all hope of them ending up together was burned away as poor Rachel met her fate due to the Joker's dastardly schemes.
Peter admired Gwen Stacy for a while, and he finally gathered the courage to actually start dating her. They dated for a while, and even though their relationship hit hard times after the death of Gwen's father, they always managed to mend things up. However, in The Amazing Spider-Man 2, Gwen suffered an injury that could not be mended after the Green Goblin dropped her into a clock tower.
While Superman may be the grandfather of all superheroes, Batman is the real star of DC recently. After the massive success of The Dark Knight, the bat-symbol became increasingly popular on clothing and accessories as Batman took the mantle of favorite DC superhero. It's now at the point where Batman fans are finding every possible reason for him to beat Superman in the upcoming Batman vs. Superman: Dawn f Justice, just because they want him to reign triumphant.
Spider-Man represents the same kind of hero for Marvel. While The Avengers have been destroying the box-office and Spider-Man has disappointed us too many times, fans still clamor for more Spider-Man movies. When the first Avengers movies blew our minds, one of the most frequently-asked questions was "where is Spider-Man?", because everyone wants to see their favorite web-slinger fight alongside Thor and Captain America.
Batman and Spider-Man are both pretty much the faces for their respective universes now, and for good reason: they are both awesome!
