"Kekekeke! Yeah. That'd be "fair" wouldn't it Kaido?"
"Wororororo!"
The great blue dragon disappears and the large, ogre of a man crashes down next to you. He readies his kanabo and starts cracking his neck in preparation for what's to come.
"This is gonna be fun!"
"You've... got to be kidding me!"
"Smoker... What should we do?"
The two only realize now what a grave mistake they made. It's easy to forget you're an emperor, given how new and comparably short you are to the other giants. But now they face Kaido standing side by side with you. There is no ignoring the matter now and no way to escape the consequences of their actions either.
"So brat."
Kaido addresses you, completely ignoring the two marines.
"Let me ask you a question. Can you hear it?"
"Hear what?"
"It. The voices. The voices of the world. Do you really hear them?"
"Of course."
"Wororororo. Well then. Let me show you something. In exchange you can show if you're really worthy of the name Emperor!"
He places one foot in front of the other and starts winding up his kanabo before pouring his heart and soul into it. It starts to crackle with raw force even before it's swung.
"Do you hear it boy?"
"Yeah."
"Then let's do a combo, shall we?"
You mimic his pose and raise Argent high in the air. Though you don't think you can quite match what Kaido is doing you can get close. Your arms swell as you activate the Dumahim and start vibrating Argent as much as you possibly can. Ripples form in the air as the waves flowing through and out of the sword distort the air around it like a mirage. The very ground shakes as you manage to sync up with Kaido and feel the name of the attack that's being etched into the world itself by the roaring force that's built up. Kaido takes a step forward and you do the same, swinging your respective weapons at the same time as you shout.

"-KAI!"
The focused power of the two swings merges and surges forward with unprecedented speed. All that stands in its way gets obliterated. The mighty walls of Marineford turn to nothing as easily as the men standing before it. Not even their screams remain as the roar of the attack overwhelms even those. For one glorious moment it seems like nothing else but the attack exists as it drowns out all else. But even something of that magnitude must end once and it did at the hands of the marines.
Standing at the foot of the fort itself with no defensive wall left to guard them are the three Admirals and the Fleet Admiral all with their hands raised. Above and behind them are the five warlords, four of them with crossed arms and one with a soiled pair of pants. Behind even them are the veterans of the marines. Garp, Sengoku and Tsuru.
"Oh myyyyyy. That was quite scary wasn't it? What are we going to do now Fleet Admiral?"
"Shut your mouth Kizaru. We follow the plan. Kaido may be a problem but if we succeed we take out not one but two Emperors in one day!"
