Monkey D. Dragon, commonly known as "Dragon the Revolutionary", is the father of the StrawHat Pirate Captain Monkey D. Luffy and the son of the Marine ViceAdmiral Monkey D. Garp. He is the also the leader of the Revolutionary Army who has been continuously attempting to overthrow the World Government. He is the most wanted man in the OnePiece world. Even though Dragon has been shown and foreshadowed to be a fearsome character, His powers have not been shown yet. He is known as the worst criminal but his bounty is still unknown. His character has been kept secret from us since the beginning of one piece but we all can tell that he will have a huge role to play in the nearby future along with other unknown members of the revolutionary army.
Even though I believe dragon can control wind and has powers related to wind, I personally believe that Dragon doesn't have Wind Logia Devil Fruit but has a Mythical Zoan Devil Fruit. I think that he is based on ancient Japanese god Fujin just like previous other OnePiece characters that have been showed such as Fleet Admiral Sengoku who had the power of Buddha another ancient god and Enel who is based on Raijin that is a god of lightning, thunder and storms. Sengoku has Mythical Zoan Devil Fruit and hence can transform into the form of ancient god Buddha, Similarly, I believe Dragon has Mythical Zoan Devil fruit power of Fujin and can even transform to his Zoan form.
Fujin is the Japanese god of the wind and one of the eldest Shinto gods. Fujin is portrayed as a terrifying wizard-like demon carrying a large bag of winds on his shoulders. I believe Dragon can take the form of Fujin and that is probably the reason why Dragon was able to save Luffy in Lougetown when he was going to be caught by Smoker. We saw a Huge Lightning and strong wind blowing when Luffy was being saved by Dragon. It was not the only plot where oda has foreshadowed that Dragon could manipulate Wind, he showed us the same type of wind power when Dragon rescued Sabo when he was drowning and brought him back to the ship using his powers. The third time it was shown is when dragon saved People from Gray Terminal. There have been multiple scenarios where oda hinted us that dragon is having wind manipulation power. And Instead of having wind logia as a devil fruit it would make sense if worst criminal of the OnePiece World will have a power of ancient god Raijin a mythical Zoan devil fruit.
Apart from his powers there is one more thing that is unusual about dragon. In the flashback when Gol D. Roger was getting executed in LougeTown,East Blue dragon was shown with no tattoo in his face but many years after he was shown to have a tattoo in his face covering the whole left part of his face.This tattoo might also have some significant meaning and relationship to either dragons power or his past.
