This is about force, if you have special abilities, you can fight beyond the level!

Superman (Dao power must reach 500 or more)

Major General (Luffy arrives in the Chambord Islands, those 200 million plus bounty supernova!) Except for the crew! ）

Lieutenant General (must be skilled and domineering, two years later, Luffy, Smoker, and Luo have the same strength!) ）

Elite Vice Admiral (Vice Admiral of the Navy Headquarters, probably such strength!) Except for the Lieutenant General of the Giants! ）

Brigadier General (Empress, Bear!) Old rascals! If you have a special ability, you can call the general)

General (except for Whitebeard, the other four emperors, the three admirals, Hawkeye)

The strongest (at the peak of Whitebeard, here I will say first, the strongest is just a statement of strength!) ）

I have roughly divided the strength above, and that's it, if there are any shortcomings, please point them out.
