Seriously, why is everything about Luffy so full of lies, and the newspaper needs to lie 10 times more about everything he does? Like, now he supposedly killed Vegapunk and destroyed an island, the fraudulent Pirate King. Random people in the world, and even the important ones, are going to have a completely false idea of the Pirate King.
OMGD the man who orchestrated a plan of such precision and destroyed Big Mom's castle and so on, etc., etc. The lie started there.
