3- SHANKS
Shanks is the captain of the Red Hair Pirates and a member of the Yonko that rule over the New World.
He is known to be one of the four strongest pirates in the world but not much is known about his powers and abilities in detail neither what is his ultimate goal.
2- MONKEY D. DRAGON
Monkey D. Dragon is the greatest enigma in One Piece.
He’s the infamous leader of the Revolutionary Army, the World Government’s greatest enemy, and is the most dangerous and most wanted man in the world.
We still don’t know his real power neither why did he choose a life of hiding, secrecy and war.
1- IM
Im is an extremely high-ranking individual in the World Government and the actual holder of the Empty Throne whom even the Five Elders bow down to. However, Im’s existence is a secret to the rest of the world.
The full scope of Im’s abilities are unknown, but the fact that Im sits on the Empty Throne, a seat whose occupant would be associated with sole authority of the entire world, and the fact that the Five Elders, who are publicly considered to be the highest authorities of the World Government bow before him and address him with a great honorific, would indicate that Im has the greatest known authority within the World Government.
