You also give to much importance to the pool of aura which doesn't indicate at all the AOP (like Knuckle said in his fight against Gon).

How stupid and stubborn you are. No I don't give importance to the aura pool! Just that each royal guards only had phew damages against an attack able to explode the head of someone like Bisky. Meruem's attack was with the intent to kill, and you know that something with the intent to kill is at the full power, it was the full power of meruem in ten or maybe gyo on royal guards off-guard, when I say their gap is pretty close I don't lie.

Youpi had trouble with a mere 50 smoke soldiers who were very weak considering Morel state

He was blinded by anger, he had some admiration so he didn't wanted to kill Morel at the beginning. Youpi was very low in fighting skills and he eveolved during the fight.

Razor has a much better AOP

Still not enough. Knuckle didn't dealt damages to youpi to hurt him. Your comparison is really bad.

Razor and Silva wouldn't piss off youpi or dealing mental damages to him, it was what knuckle was doing, so Youpi watsed a lot of aura in his explosions. Even a 100% morel would run out of aura before youpi. So same for razor and silva, they would run out of aura then die, their aura pool is of course under 100k aura.

Dragon head is too slow for Pitou's speed, pitou would instant kill chrollo and hisoka. same for shoot and zeno, zeno isn't able to fight pitou. and shoot would do nothing, he must touch pitou with his right hand, and Pitou with he Terpsichora has a huge speed and reflex, she would instant kill him if he is near her.
