He revealed his power in Episode 54, Chapter 100, a powerful malevolent wind appeared in Lougetown that could destroy metal canons, structures and ships. And also a Lightningball appeared and hit Captain Buggy .It might be a "Storm" or some "Cloud Controll" that manipulates the Sky Weather.. .In my own Theory I think "Monkey D. Dragon" has an ability to manipulate the Sky. And can travel the whole Grandline without sailing his Galley and without being detected by anyone. I think he can turn himself into a different types or moods of "Wind".Just like what happend in the Lougetown before "Captain Buggy The Clown" attempted to cutoff Luffy's head, the wind blows acting so different. Its like something is just about to happen there or that blow of wind represents that there might be something arriving in the Lougetown island. The other strawhat crews like Rolonoa Zoro & Nami notice that odd feeling about the wind and the sky.

I think "Monkey D Dragon" is very Powerful and Brilliant Man but i think he dont want his power to be revealed because he knows that many Pirates and Marines will hunt him down. And it is a wise choice to for him as founder and for the Revolutionary Army to hide his identity or any information about him to avoid unnessesary actions that may lead his Revolutionary Army into riskful situation or downfall.
