Ambitious, shrewd, and a strong leader. He thinks before he acts, has a good mind for the bigger picture, and works hard for a dream that may never happen. Better yet, his dreams and ambitions are often adopted by those around him. Of course, his goal of a peaceful world between mutants and humans have force him to compromise his principles and manipulate those around him. Professor X is a quintessential Slytherin
Like a lot of Slytherin, ambition is one of Booster Gold’s key character traits. He’s a guy that came from the future to use advanced technology and historical records to become a rich and famous superhero. Booster desperately wants to be admired and respected. He’s still heroic, but his tendency to sell his name for a quick buck gives him a distinct Slytherin vibe.
At fist glance, you’d probably put Batman in Gryffindor, or at least Ravenclaw. But think about it. Who else but a Slytherin would dedicate their lives to building up both their minds and bodies until perfection? Remember, Batman’s most useful weapon is his ability to think his way out of any situation. Besides, Batman would probably put himself in Slytherin just to keep an eye on everyone else.
Again, Spider-Man’s a character most people would put in another house. Spider-Man is plenty brave, smart, and has always been written as an everyman hero. But what’s really important is that Spider-Man originally used his powers for personal gain, which indirectly led to the death of his Uncle Ben. Even though Spider-Man swore then and their to use his great power responsibly, he constantly struggles with the temptation to take the easy way out. He’s basically a Slytherin that tries really hard to act like a Gryffindor.
If Slytherin are basically Hogwart’s popular kids, then Emma Frost would be their queen. She’s intelligent, attractive, and worst of all, she knows it. Emma Frost makes Draco Malfoy look like Forrest Gump. Hell, Emma Frost was an actual super villain for the majority of her existence and was indirectly responsible for the death of an entire planet. Voldemort eat you heart out.
