With great power comes great responsibility and with great spider-powers comes the opportunity to become Spider-Man.
Miles Morales was an average kid (besides being pretty smart) who happened to be in a situation that lead to him gaining spider-powers. With the death of Peter Parker in the Ultimate Universe, Miles decided that he should do the responsible thing and become the next Spider-Man. He has the powers and the world is full of threats that need to be taken care of.
The problem is, Miles is young and inexperienced when it coms to being a superhero. For all of Peter Parker's time as Spider-Man, after all the battles he fought and won, it still wasn't enough to prevent his death. Miles has had a few fights under his belt but is he really ready to become the next Spider-Man?== TEASER ==
If Peter Parker could do it, why not Miles Morales?
Peter was a little older. While both have spider-powers, there are some differences. Peter's were mainly super strength, agility, spider-sense and wall-crawling (he was able to design web shooters off his dad's research).
Miles' powers are a little different. He's just getting a handle on his camouflage and venom-sting powers. Fighting superpowered villains while not fully understanding how his powers work or if they'll suddenly give out while being used isn't the smartest idea.
What's odd is Miles is being allowed to be a Spider-Man despite his young age and lack of experience and guidance. He might have been able to deal with Electro but winning a couple battles isn't enough to allow him to graduate to a full-fledged hero. Nick Fury gave Miles his blessings by giving him a new Spider-Man suit.
For a guy that felt deep guilt and remorse over the death of Peter Parker, letting another young kid step into those same shoes is insane. He told Mary Jane that he met Peter when he was an baby. He was happy when Peter gained powers and was planning on grooming him. Yet, he allowed him to place himself into danger for a long time before insisting he be trained.
It was during the time when he was supposed to be under the Ultimates care that lead to his death. He was shot saving Captain America's life. During the chaos afterwards, the Ultimates didn't seem concerned that a shot kid disappeared. They assumed he sought out medical care as they regrouped back at their headquarters. Fury could have done more to make sure he was alright.
Miles is an extremely intelligent child. He's been studying footage of Peter Parker but that still isn't enough to fully prepare him. He could use some actual training with experienced heroes but trying to fit that into his school schedule without his parents or friends finding out could be tricky.
The idea that Fury is willing to give Miles "one chance" without a single bit of training is ridiculous. He's seen what happens when a kid with a decent amount of experience puts himself into dangerous situations. Miles was able to take on Electro but was it because of his abilities or because he got lucky?
Miles has shown huge potential. He definitely has what it takes to be a great hero. The last thing we need is another dead Spider-Man. Ultimate Peter Parker was a beloved character but Miles has earned the right to be the next Spider-Man. That role is more than just about having spider-powers. Miles needs proper and official training. Nick Fury needs to make sure that happens. Miles could be a great hero and Fury shouldn't make the same mistake twice.
