Fenrir is Tagg's male Lucario, who he met as a Riolu at Floccesy Ranch, Fenir having sensed his Aura. Upon meeting him Tagg lampshaded the cliche of an Aura sensitive taking a Riolu as a party member, but did it anyway after fighting him in a battle. So far, Fenrir has proven to be a welcome asset in Tagg's new Unova team.
Fenrir is mostly stoic, but loves a good fight and challenging other mons to fights, as seen when he challenged Mirage and Kohai out of nowhere. He also can have a bit of a pigheaded streak when it comes to playing videogames, which got him in trouble with Audrey.
