As I don't know the story well, I can't say for sure what the main events are.
I'm not really familiar with the 'the headless man Molbo story'. It might be a very specific or regional story. Maybe it's about a man named Molbo who has some strange or supernatural encounter related to being headless.
No, the Headless Horseman origin story is not based on real events. It is a fictional creation that has emerged from the realm of folklore. While it might incorporate elements like the Hessian soldiers which were real, the idea of a headless ghost riding around is pure superstition and a product of people's imaginations over time.
The main events in the Spider - Man 2 story include the appearance of Doctor Octopus. He starts causing chaos in the city with his powerful mechanical arms. Spider - Man has to step in to stop him. Peter Parker is also struggling with his identity. He wants to be with Mary Jane but his duties as Spider - Man keep getting in the way. There are intense fight scenes between Spider - Man and Doc Ock which are crucial to the story.
Since the story is unknown to me, I can only guess. Maybe the main events could be centered around the man experiencing a series of unfortunate incidents one after another, such as getting into accidents, having financial losses, or being misunderstood by people around him.
In Mega Man 1 story, it starts with Dr. Wily's betrayal. Then Mega Man's battles with Cut Man, Guts Man, Ice Man, Bomb Man, Fire Man and Elec Man are the key events. Each battle is different, like when facing Ice Man, Mega Man has to deal with his icy attacks. Finally, Mega Man confronting Dr. Wily in his lair is a major event as well.
One main event is Scott Lang getting the Ant Man suit and learning to shrink. Another is his fight against Darren Cross. Also, his team - up with Hank Pym is important.
In the story, the man might encounter the wolf in the forest. Maybe he tries to escape from the wolf. And perhaps in the end, either the man outsmarts the wolf or gets rescued.
One main event is the appearance of Ivan Vanko as a villain. He creates his own armored suit and attacks Stark. Another is the government's attempt to get Iron Man's technology. Also, Stark's discovery of a new element for his suit is a big event.
One of the main events is the main character getting involved in a new and dangerous mission. Another is the growing suspicions within his family. His wife starts to notice his strange behavior more often.
As I don't know the Pi Man story specifically, I can't tell the main events. It could involve events related to the discovery of something related to 'pi' by the Pi Man, like finding a hidden pattern in nature that is based on pi.
