Probably characters like Scarlet Witch, as her actions were closely related to 'M Day'. Also, many of the younger mutants who had to face the new reality after 'M Day' might be main characters. They could be struggling to find their place in a world where the mutant landscape has been completely changed, and their powers, or lack thereof, are a big part of their journey.
There could be a lot of well - known X - Men characters like Wolverine, Storm, and Cyclops. Since 'M Day' had a major impact on mutants, these characters would likely be involved in some way, either directly affected by the events or trying to deal with the consequences.
Scarlet Witch is one of the main characters. Her powers play a crucial role in creating the alternate reality of the 'House of M'.
The graphic novel features characters such as a 1602 incarnation of the X - Men. Magneto also has a role in this different - time - line story. These characters bring their own agendas and powers to the 1602 world, and as they interact, they create a story that is both familiar in terms of their basic traits but also very new because of the historical backdrop against which they operate.
The Scarlet Witch is a key character as she creates the new reality. Also, Magneto plays an important role as a powerful mutant in this new world order.
It could be about a special event in the Marvel universe called 'M Day' presented in a graphic novel format. 'M Day' in Marvel often involves significant changes to the mutant population, like the depowering of a large number of mutants. The graphic novel might detail the events leading up to it, the chaos during, and the aftermath.
It likely includes a wide range of characters. For sure, there would be Spider - Man, both the classic and new versions. Also, Captain America, Iron Man, and Thor are probably in there as they are central to the Marvel Universe across generations.
I don't know for sure without reading it, but it could be a group of new or under - explored Marvel characters.
Jessica Jones is one of the main characters. She's a tough private investigator with a super - powered past.
There are several main characters. Spider - Man often features prominently. His acrobatic abilities and witty remarks are always engaging. Also, Iron Man, with his high - tech suits and genius intellect.
Black Bolt is one of the main characters. He has a powerful voice that can cause destruction. Medusa, with her prehensile hair, is also important. And there's Karnak, who can see the weakness in things.
I'm not entirely sure, but it's likely that the Ghostrider of 2099 is one of the main characters. There may also be some new characters created specifically for this 2099 version of the story.
