[Marvel] What is stopping Multiple Man taking over the world with millions of copies of himself?
gpt
Each multiple represents a different aspect of his personality. Some may be more shy, pacifistic, or introverted, while others may be more devious, shady, or untrustworthy. And the more multiples he creates, the more they deviate from him.                 

Point is he has no control over his multiples aside from being able to reabsorb them when he wants. If he created millions of copies of himself they would all want different things and many would just ignore him and walk away. The X-Factor investigations run covers this really well.
