Wilhurt is unique among the other wolves, as his fur is black while the other wolves are often gray. While it is not confirmed by LEGO or in the television series, Wilhurt appears to be Worriz' right hand man, as he is the only other wolf who wears a cape and is often seen with Worriz.
- Wilhurt's name most likely comes from the pun of "will hurt" as in "I will hurt you".
- In the television series and in a promotional image on LEGO.com, Wilhurt wears a cape that is identical to Worriz. None of the Wilhurt Minifigures included in LEGO sets include a cape for Wilhurt, except for 70009 Worriz's Combat Lair. Though the instructions say to give Windra the cape.
