Now Adays you're average celestial dragon makes spandam look yonko level however I don't think that was always the case I believe they got weaker over time because they haven't had to fight for hundreds of years each generation weaker than the last.
Doffy is a fine example of how powerful a celestial dragon can be of they are forced to be strong
The gorosei, imu and Garland are potentially the last remaining actual powerful celestial dragons
But if you look at their resumes the celestial dragons where seemingly quite powerful
They won against the ancient kingdom in a war
They seemingly wiped out the lunarians, how do you wipe out a race of people that are seemingly invincible long as they have the Flames on
They where able to control the world and keep the status quo for hundreds of years
I'm willing to bet Dragon wasn't the first to start a revolutionary army or resistance group.
Over the years every uprising and resistance got crushed by celestial dragons
But over time has they began forming the world government and vuilding up fhe marines, the Admirals and all of those deterrents they got complacent they figured
Those filthy bugs can't touch us
So they grew weaker and weaker each passing generation until we got the fish bowl wearing jackasses we have today
