- The card art may be explicitly referring to the legendary boar which caused the death of Diarmuid. (This is supported by the boar seemingly-chewing at a broken Gae Buidhe).
- The card art may also be a reference to a piece of Type-Moon April Fool's art.
- This boar - a.k.a. the Calydonian Boar, appeared in FGO 2016 Summer Event as a Boss-type Enemy.
