This never happened.
This is Linlin's durability.
Linlin, on her own accord, used hardening, used her immense body weight, leaned forward thus putting the said body weight in use to produce a counter force to the force of WCI Luffy's punch and her arm rattled. Linlin used her own physical force and a layer of haki and leaned forward in a more advantageous position to have her arm rattle from a punch from WCI Luffy, that is pure physical force and not lethal. Occam's razor denotes she used COA and counterforce since she needed to use them.
Kaido taking a free fall from 10k meters and takes an onslaught of G4 attacks, without any protection, and ends up being disappointed
vs
Linlin falling from a castle and leaning forward putting her body-weight in use, uses hardening, counter force, and it still makes her arm rattle after only one G4 attack
Brulee, the eight daughter and the nineteenth child of Linlin, showed concern for Linlin as well.
She knows of Linlin's durability, and has known it her entire life, and was worried when the castle crumbled, and was explicitly expressing her concern for Linlin.
Moreover, Zeus, a homie infused with Linlin's soul, rushed over to save Linlin from the fall, and alleviate the impact of the fall.
Zeus is bewildered and is expressing his concern for Linlin as well.
Linlin was preparing a homie to guard against a laser from Franky.
Kizaru straight up kills her lmfao.
Jimbei was tossing her around like a bowling ball.
And welcoming an attempt to kill him. Basically taunting her.
The same Jimbei that knew he could only buy time before he dies to an Admiral
It's Akainu, but Akainu is only marginally stronger than Kizaru, if at all.
Someone with lackluster COO cannot even hope to spot Kizaru, let alone engage him in a fight.
His DC output is amazing, and we have yet to see him use awakening.
He casually destroys a giant mangrove tree that dwarfs houses
Kizaru's lasers create massive explosions, from a distance
With his Yasakani no magatama he has a large AOE
When it comes to Akainu, refer to what I said above.
Linlin, on her own accord, used hardening, used her immense body weight, leaned forward thus putting the said body weight in use to produce a counter force to the force of WCI Luffy's punch and her arm rattled. So, Linlin used counter force and another layer of protection on top of the counter force to match Luffy's punch, and her arm rattled still. Take note that Luffy's punches are in no way lethal, as it is the blunt physical force behind them. So Linlin used her own physical force and a layer of haki and leaned forward in a more advantageous position to have her arm rattle from a punch from WCI Luffy, that is pure physical force and not lethal.
What happens when she gets punched by Akainu? Someone who has more potency behind his attack than WCI Luffy, as he was able to match WB's gura punches
and as an Admiral, and a certified top tier, has better physical stats. On top of having more attack potency behind his punch than WCI Luffy, Akainu also packs something Luffy lacks (not talking about a brain). Akainu has one of the highest offensive powers when it comes to devil fruits, and one of the most lethal offences in the manga. Akainu's lethality>>>>>>>>>(infinite number of >)> WCI Luffy's lethality, Akainu's attack potency>>>>>WCI Luffy's physical force behind a punch. Linlin's arm, while using a counter force and another layer of protection on top of the aforementioned counter force, was rattled by a purely physical punch from someone far weaker than Akainu, and someone who lacks lethality, something Akainu excels at.
As the initiator, aka the offence, Akainu is far more likely to penetrate the stagnant mass, aka the defense.
Zeus and Prometheus are useless against Akainu. Linlin has never used haki in conjunction with them. Moreover Prometheus is a one shot ready to happen when facing Akainu.
So that leaves Napoleon Linlin against Akainu. Akainu already has better haki feats than Linlin,
and has the on panel haki that can probably hurt Linlin, as Luffy implied it would be enough to pass Kaido's tough scales,
who has a better dura hype than Linlin, Kaido taking a free fall from 10k meters and takes an onslaught of G4 attacks, without any protection, and ends up being disappointed
vs
Linlin falling from a castle and leaning forward putting her body-weight in use, uses hardening, counter force, and it still makes her arm rattle after only one G4 attack
and scaling from Kizaru better speed feats as well. In cqc he is more skilled, having been trained in various styles as a marine.
If it's the hurr durr magma homie argument, Akainu can absorb the residue magma around him thus limiting the homie, or limiting the option of creating the homie, or luring it in and thus causing it to betray Linlin, something that already happened in the manga. Akainu should be also able to consume the magma around the homie making it weaker and weaker. Akainu should be able to consume the entire homie into his body and maybe kill him like that.
Akainu got back up from a sneak punch from the WSM, enraged sneak punch from someone hyped to possess the power to destroy the world.
The first punch landed by surprise, yet Akainu got back up immediately, launched a counterattack and melted half of WB's face
and not even that could stop him, as evident here and explained
What's Linlin's offence going to do to him? A very limited offence as well. This is enraged Linlin using haki
Not even in the same league as an enraged gura punch from the back by the WSM.
Lol no.
Kaido, I've stated is debatable, however, you need high level COA, that the Admirals have displayed thus far, hence they were not present at Kaido's executions or he would have been dead.
Nah, any Admiral can do that.
Kaido hit an exhausted fatigued, FS-less Boundman in an unprotected area
And all the Admirals were dunking on him. And they had to restrain themselves not to cause damage to MF.
The Admirals were restricted due to the battle taking place in MF, aka their home turf. Akainu was trying to preserve the island and the town.
He mentions it twice.
This is what happens when unrestricted Admirals can
fight fully.
All the Admirals were fighting WB perfectly fine.
Akainu melted half of his face even though he was attacked from
behind with a surprise attack.
And yet he could still continue, as evident
here and explained
What's also interesting to note is that he first thing Akainu did was build a tunnel underground to avoid unnecessary battles, and went right back to chasing Luffy. Whitebeard was literally not even the second thing on Akainu's mind. He was an annoyance just like everyone else, keeping him from getting to Luffy.
Wb himself and Akainu stated MF is WB's place of death. Akainu didn't have WB on his mind, he was busy trying to exterminate the two future threats, Luffy and Ace.
Akainu's sole focus was on getting rid of the
threats of the future, WB was just an annoyance, like anyone else, in his way to Luffy and Ace.
Aokiji morphed around WB's attack, and was preparing an attack from close distance that had to be
stopped by Jozu.
WB tried to prevent Kizaru from attacking Luffy, with Kizaru not even knowing WB was there, and yet WB did nothing to Kizaru. Kizaru then pinned his bisento down, using one leg, and
shot a hole in WB.
None of them had a problem with WB in duels. The war when started was never debatable. The outcome of the war was never questionable.
