I know that Rogue can absorb “memories” when she touches someone, but that’s a very vague, handwavey term. Does she absorb practical skill sets as well? By that I mean not just the theory but the skills itself. Example- if she touched a martial arts master, does she just know how to throw a punch properly, or can she fight at a master level?
From her profile on Marvel.com (emphasis mine):
Rogue's mutant ability requires skin-to-skin contact to absorb memories, powers, personality traits, physical talents, and strength.
The combination of memories + physical talents indicates to me that, were she to touch a martial arts master, she would be able to fight at that master's level, as if she were that master.
