i shouldn't have paused working on my big bang fic to write this, but oh well.
anyway, almost certainly an au, as I highly doubt Oda has this planned. enjoy.
"I cannot wait until he sees your dead body lying here, Law," Doflamingo said, standing over Law's body.
Law barked in pained laughter, his arm moving up to press at his face as the laughter worsened.
Taken aback by the sudden noise, Doflamingo asked, "What the hell is so funny?"
"I can't believe you haven't seen it!" The laughter reached a fever pitch before it was cut off in choking coughs. "Fuck, something's definitely broken. Cap'n's gonna be pissed." There was another huff of laughter. "Anyway, since you haven't noticed, you big pink sack of feathers, I'm not Trafalgar Law."
There was a moment of silence before Doflamingo slammed his foot onto Law's stomach. "Law is the only one with the Ope Ope no Mi and you know it, scum," he hissed, grinding his heel in.
'Law' coughed up some blood, but he was still grinning. "The Shambles is a marvelous ability," he mouthed off, "since it swaps people's consciousnesses." He turned his head and spit out some blood that had pooled in his mouth. "Penguin, First Mate of the Heart Pirates at your service," he mocked.
"DOFLAMINGOOOOOOOOOOOOO!" Luffy yelled from somewhere below, in the ruins of the building.
"Tick-tock, Doflamingo," Penguin said, grinning manically in Law's body. "Time's a-wasting!" He gripped Doflamingo's ankle. "What'll you do? Kill me then deal with an absolutely even more enraged Strawhat? Or will you deal with him and let me bleed out in the meantime?"
Instead of responding, Doflamingo ground his foot further into Law's stomach. Penguin only huffed in pain, gritting his teeth.
"Well? Which will it be?" he taunted again.
"I'm going to kill you and then find the rest of you rats and kill all of them too!" Doflamingo growled, raising his hand.
"Torao!" Luffy's voice was closer.
"Looks like your time's up, dickface," Penguin said. "Strawhat-ya!" he yelled, mimicking the way Law would have perfectly.
"Doflamingo! I'm going to beat the shit out of you!" Luffy yelled.
