Killian Arquette ([mlb] faewren)

Faewren is an eccentric and loud miraculous holder that ocassionally pops in to assist Chat Noir and Ladybug with fighting pesky akumas. Neither Chat nor Ladybug knows why he suddenly appeared to help out or where he obtained a miraculous, leading to a bit a distrust at first, but he proves to be welcome help using his miraculous power Fairy Ring that creates a temporary ring-shaped barrier that's unable to be crossed by those afflicted with an akuma. 

• Faewren often calls others "Fam", but calls Ladybug "Chief".
• He has a friendly rivalry with Chat Noir, but it tends to become more friendly after Chat Noir discovers his identity.
