Smoker is a smoke man. He can "create, control, and transform into smoke at will" – [One Piece wiki](http://onepiece.wikia.com/wiki/Moku_Moku_no_Mi)

Caesar is a gas man. He can "create, manipulate, and transform into gas at will." – [One Piece wiki](http://onepiece.wikia.com/wiki/Gasu_Gasu_no_Mi)

Since smoke is a gas, could Caesar control Smoker when he turns into smoke?
