I love the color spread. It gives me Thriller Bark feels. Especially, Franky's Zombie Night impression. (Tumblr lost its mind over LuNa, tho. It makes me sick...)

As for the chapter, welp... I kinda knew it was going to be something silly. Turns out Gear 4th is Bouncy Ball Nightmare Luffy. The sweet tats may or may not allude to those multi-colored ones I remember from childhood.

The longer I think about it, the more "simple but brilliant" it gets. The trick with G4th is that Luffy doesn't actually punch Mingo but he simply releases all the force he used to pull the arm inside his body (which is a lot if you have ever tried to press a bouncy ball together). That way there is no loss of force as in his other techniques. (rubber bands lose more force when rebounding than bouncy balls upon bouncing due to shape and material properties.)
