[[Chat Noir]]'s civilian identity from [[prototype design|the beta premise]] of [i][[Miraculous Ladybug]][/i]. Originally he didn't have a name, but both community and creator decided Felix as his name.

Supposedly, he was an aloof and cold character, with a string of bad luck occurring around him because of a magic ring currently stuck on his finger. The reason he chased after [[ladybug (character)|Ladybug]] was because he was told that a kiss from her would remove the ring.

His Chat Noir form and [[adrien_agreste|Adrien's]] are very similar, but Felix has shoulder-length [[blonde hair]], prominent [[blue eyes]] instead of [[green eyes|green]], and a larger [[bell]] on his [[bodysuit]].

Felix's design and name were later retooled into Adrien's cousin [[Felix Fathom]].
