Rate ODAs Favorite of SHC

Sanji - When asked about the coolest character in a recent interview. Oda immediately thought of Sanji and said that he thinks that fans would find him very cool. Oda also said Okamas are his favourite and linked them to Sanji. He also linked his childhood show, Super Sentai to Sanji. And literally gave a lot his own background to Sanji.....( previously working in the baratie/chain smoking/Pervert). Sure Oda doesnt realiss that hes treated Sanji bad in terms of fights. But you cant lie that hes focused a lot on him and general thinks hes done a good job.
