Law's Devil Fruit, Kidd's Devil Fruit, Kaido's Devil Fruit, Big Mom's Devil Fruit, Brook's Devil Fruit (Big Mom and Brook devil fruits should enhance his soul and even make him able to manipulate it), Sengoku's Devil Fruit, Whitebeard's Devil Fruit, Marco's Devil Fruit, Jozu's Devil Fruit, Boa Hancock's devil fruit (important), Doflamingo's and his subordinates' Devil Fruits, Gecko Moria's Devil Fruit, Three Admirals Devil Fruits, Luffy's Devil Fruit (since he is there, I doubt Hector will ignore any devil fruit), Smoker's devil fruit (great mobility, ability to fly by turning lower body to smoke, being unharmed by most attacks), Crocodile's Devil Fruit, Issho(Fujitora) and Armaki's Devil Fruits, Since He went to Impel Down then I assume he took Douglas Bullet's Devil Fruit power, Dr. Vegapunk's Devil Fruit ability (it will surely make him even smarter the brain-brain fruit, which make the brain bigger and thus you become smarter but since Hector can manipuate his body he can totally compress the huge brain into a smaller one with same capabilities), Foxy's Devil Fruit too. a hope he copied Rogue's power cuz I'd like to see him copy the biology of Kaido and King(Lunarian), Fishman Biology and learn Fishman Karate, Vinsmoke for their enhancements, this is the most important powers that he should copy/steal.
