Well, it's Deadpool. His unique sense of humor and his anti - hero nature make the graphic novel stand out. He breaks the fourth wall constantly, which is really entertaining.
Obviously, the main characters are the two Deadpools. They are both versions of the same character but with potentially different backstories and personalities in this graphic novel.
Well, one key point is the battle between the two Deadpools. They likely have different motives or versions of themselves that lead to the fight. Maybe one is from an alternate universe.
It's likely about the adventures of Catwoman. Maybe it shows her heists, her battles against villains in Gotham, and her complex relationships with other characters in the DC universe.
Definitely 'Deadpool vs. Thanos'. This one is popular because it pits two very different but equally interesting characters against each other. The battles between Deadpool and Thanos are epic, and the comical banter throughout the graphic novel adds to its charm.
