Sharing some interesting concept art for Miraculous Ladybug and Cat Noir season 4.
All these concepts were shown in behind the scene with Lindalee Rose video about Miraculous Ladybug toys from Playmates.
You can see a partial realization of these concepts in the already released figures Miraculous Ladybug Playmates articulated doll figures. Like Ladybug and Cat Noir's Winged Backpacks, or Rena Rouge's hooded cape.
It is not known exactly how much these concepts repeat the images from the animated series, but as you can see the Cosmobug mask is pretty same in the series as it can be seen in concept. Co maybe we will se Rena Rouge in cape and fusion of Miraculous Ladybug and Bee powers.
