This from the Miraculous Ladybug Anime, the one that got cancelled. The image I found was from Pinterest, and the person from Pinterest, who uploaded this was Alexandra Slynko.

This Felix is not exactly the same as the Felix in the 3D one because Felix IS Cat Noir. And also the fact he's not a villain(?), but rather a different version of Adrien Agreste; so he's a hero. Or... Is he?

After finishing: Yo, this Miraculous ain't so cute, huh? The original tale of MLB is so tuff yet so dark bruh 😭
