Here is an interesting thought! Teach himself said that his original devil fruit “truly holds the power of THE devil.” So could it be that due to this he is able to absorb other “devils” which in turn give him the power of that fruit. Also could it be that he can only do this once, after all Teach has been considered a master planner as everything he has done seems to be part of a giant plan he has laid out. I mean who else would go after Whitebeard, granted he didn’t until he was already injured. None the less he went after a specific power just like he waited to eat a specific fruit.
