- Wilfried is called "Pére WI2NY" by the fans because of how fatherly he acts towards the fans and because of his cameo within Ultimate Mecha Strike III in "Gamer".
- While Wilfried loves all of the characters, some of his favorite characters are Chloé Bourgeois and Alya.
- He likes Chloé in both her regular and akumatized forms.
- He likes Alya because she is the best friend, the sidekick, and doesn't hide in the shadows with her blog. "She is like the Jiminy Cricket (Pinocchio) for Marinette."
- His favorite male character is Gabriel Agreste because "I'm a father and I love my wife ... I can relate to him."
- The Evillustrator's powers interest Wilfried because Wilfried is a storyboard artist.
- Between Ladybug and Cat Noir, Wilfried prefers Cat Noir.
- He likes Cat Noir's night vision, puns, cool attitude, forced style, and bad timing.

- His absolute favorites are A River Run Through It and My Name is Nobody.
