The chapter was also a theorists dream. Like:

Chapter 784: First appearance of Gear Forth. Chapter 478: First appearance of Nightmare Luffy.

Knew it already? Alrighty then.

Chapter 894: Luffy's new Gear forth form, Snake Man, is mentioned for the first time. Chapter 489: Boa Hancock, the Snake Princess, is mentioned for the first time. (Also, Lola mentions her mother for the first time and gives Nami Big Mom's Vivre Card.)
