Just going to share my thoughts about this never ending discussion.
Now im going to write this down in few points.
1. About the title, what does that mean?
People keep arguing about King & Queen and i'll jump right into the conclusion, yes King is stronger than Queen.
But, the major issues in here is few or maybe many people assuming the power gap between King & Queen is so big. In fact maybe its just like Kaku and Jabra doriki all over again.
Now, there is 2 major aspect in combat/fight.
There is an offensive aspect and defensive aspect.
2. King's Feats
King's feat so far is
- Kicking Big Mom Ship. (Offensive)
- Goes to war with Kaido, Queen, and the Beast Pirates 20 years ago. (Offensive and Defensive)
- Attacking Sanji and goes full Zoan form when Sanji trying to save Momo. (Offensive)
- About his fight against Marco, we dont know anything except he get up from Marco's Blue Bird in chapter 1006. (Defensive)
Now, we can make a conclusion if Oda showed King's feats is about his Offensive aspect more than Durability aspect.
3. Queen's Feats
Different from King, Oda already showed so many Quee 's feats so far.
- Doing a Brachio Bomber to Hakiless Big Mom in Udon Prison earlier (Offensive)
- Goes to war with Kaido and King 20 years ago against Oden and The Red Scabbards (Offensive and Defensive)
- Ice Oni and Plague Bullets (Offensive)
- Cyborg thingy inside his body (Offensive and could be Defensive too)
- Black Cofee / Laser Beam attack (Offensive)
- Got hit by Marco's Phoenix Claw in human form and looks clean one chapter later. (Defensive)
- Got hit by Marco's Phoenix Brand too before Phoenix Claw. (Defensive)
- Got Slapped by Chopper in Zoan Form (Defensive)
- Got hit by Sanji's Diable Jambe Rotisserie + Perospero Candy Arrow in Zoan Form (Defensive)
After we breaking down King and Queen feats until last chapter, now we can see if Queen feats so far shitting on King.
But because of the hierarchy system, you have an argument about King is stronger than Queen.
Now to sum it up, if we put in a number/stats, this will be the number.
King The Wildfire
Attack : ββββ
Defense : βββ
Queen The Plague
Attack : ββ
Defense : βββββ
