I think the most powerful dragon pokemon is Rayquaza because if it have four moves like outrage,flamethrower, suft and thunderbolt with a high speacial attack it will be very strong
Well, I'm not so sure on that one. Because this is the legendary club, I got two, (Latias and Lotios) and the two পছন্দ for non-legendaries are Salamance and Garchomp
i whould say Arceus if he is dragon but if hes not id say................................................................stektins the coolest glitch pokemon!
