I chose Ragnarok because according to the comics, when Thor dies Reed Richards (Mr. Fantastic), Hank Pym (Ant-man), and the great Tony Stark (Iron man) find a way to clone his DNA. While Stark fused him with stark technology he became a cyborg Thor. He then went mad because he thought he was the real Thor and that the other heroes were lying to him so he became a Villain with not only Thor's powers but a hammer made from adamantium and vibranium (not as good as Mjölnir but still very powerful) so anyone could wield it. During the anti-registration act Ragnarok kills allot of the anti-registration heroes such as Bill Foster (Black Goliath). But the Villain did not last long, facing off against Ororo Munroe (Storm) and Hercules he had his own hammer rammed through his face under the command of Odin. With that not being the final blow what initially put Ragnarok down was that Reed Richards (Mr. Fantastic) deactivated him with a vocal code. the way i see Ragnarok is a pissed off mixture of Thor and Ultron, sounds like the avengers would have their hands full with that one.
#4: Tony Stark/ Iron Man
Take away the suit and what does he got? Simple... playboy, genius, billionaire, philanthropist. He's as arrogant as it gets, also as rich and smart as it gets. plus he has a bad ass suit. how could you go wrong.... But really his expertise in mechanical and electrical engineering competes with the great minds of Reed Richards (Mr. Fantastic), Hank Pym (Ant-man), and Bruce Banner (The Hulk).in the marvel universe he is considered one of the most intelligent and charismatic heroes of all time. unlike batman's belt iron mans suit does lack a few things in some cases, yes he can fly, shoot repulsor rays, and has j.a.r.v.i.s telling him every thing going on such as power levels and how many enemies there are around him. but the downfall is that if the suit loses power in the field he is pretty much screwed.. but one thing is certain about Iron man, he always finds a way to accomplish what he sets out to do.
#3: The Joker/Villain
He's sick, sadistic, crazy and mysterious. I mean he's been around this long and no one even really knows who he is or his real name. Anytime he is up to his games Batman knows his hands are full and its always the best read. (and i'm a die hard marvel fan by the way) He tricked and seduced Harley Quinn and turned her into the psychopath she is. Using her love for him he's managed to become one of the most ruthless villains of all time. killing without second thought or remorse, he has shot Barbra Gordon (Bat girl) leaving her paralyzed from the waist down, kidnapped Alfred Pennyworth (and just recently cut his hand off). This man is so nuts he even jumped over to the Marvel universe and picked a fight with the hulk.. now if that's not crazy then i don't know what is.
#2: The Wolverine
The Wolverine has stood the tests of time, being a veteran of multiple wars in history such as the civil war and WW2, he has a long and often dark history. He's an all around bad ass that has shown time and time again. He also has a huge heart which in some cases are a downfall. though he has been a loner and in parts of groups such as the X-Men and the Avengers, He's undoubtedly one of the most versatile characters in the comic universe. Fearless in everything he does, he wouldn't back down from the hulk who ripped him in half (literally), having to kill the only woman he ever loved to save the world, and in 2014 ultimately dying. what intrigues me most though is that there is still so much to learn about his eventful past.
#1: The Hulk/Bruce Banner
Not only is the hulk the strongest superhero ever written, but possibly the smartest (Bruce Banner). i picked the hulk for my number one spot because when he was written he was some what an underdog, only having 5 issues published the incredible hulk was not a best seller, so marvel decided to put him as a guest star in the fantastic four. Of course two of the biggest strongest men in marvel comic history had to come to a showdown (probably because the hulk always let it be known that he was the strongest and it didn't matter who knew or not) but the thing could never get the best of the hulk. the angrier he gets the bigger he gets, the bigger the stronger. He even got to the point of strength that he picked up a mountain..... yes a mountain and smashed crusher creel (Absorbing Man). But as Bruce Banner he has accomplished things such as controlled fear and emotions like rage to keep somewhat control of the hulks body and teaching hulk the right way to help people. Bruce is also considered one of the most inspirational and intelligent heroes in comic history, from helping Tony Stark tuning up his suit, to figuring out a cure for the red hulk, or just smashing puny gods.
And another 10 honorable mentions.
