- Caesar was designed after pierrot clowns/clowns as a whole, hence why his first name is "Clown". This is also likely why he was given white skin and has defined lips and eyeline
Caesar’s scientific knowledge allows him to use the Gasu Gasu no Mi to a much further extent than any other user would be able to. It’s a fruit where scientific knowledge will dramatically increase the potential of its abilities
- Monet was rescued alongside her little sister Sugar 13 years ago by Doflamingo and was fed the Yuki Yuki no Mi afterwards. Monet feels such deep gratitude towards Doflamingo for saving her life that she’s even willing to put her own life on the line
Monet is farsighted and has a hard time seeing things up close, to the point that she needs very thick glasses to write
While not outright confirmed, the card does seem to imply that she is dead, with the final point on her timeline being "pierced through the heart by Caesar"
- Not much about Vergo, but something interesting is how while using Armament Haki, he was able to keep the consistency of the bamboo cane he used (allowing it to inflate like that), I guess similarly to how Luffy was able to keep the consistency of rubber with Gear Fourth
