He can temporaily(probably didnt spell that right) absorb the devil fruit powers( yet not use them, to my knowledge) from a living devil fruit user by touching them, ex Blackbeard grabing Luffy and smashing him down on the floor in Impel Down and it hurt Luffy. His rubber body would protect him under normal circumstances yet like I said Blackbeard absorbed his devil fruit temporaily while Luffy was in his grasp.
