>>101107477not a theory, Astruc confirmed that 3D was explicitly so the spots would be easier to animate. the design is also so that "it would be recognizable from every angle," so basically just 100% spots
>>101112003actually they were the same "attractive blond boy" deuteragonist, fans just nicknamed him Felix when the PV came out, and when the show was actually finalized (3D animated) it was revealed the name was Adrien, but because of the clear departure in personality they kept Felix as the 2D version's nickname and Adrien for the 3D
kinda like how the protag was always Marietta/Marinette, but following Felix's convention fans nicknamed the PV version Bridgette
