- This creature can be seen in Joe Star of Dreams's DMRP-04魔 artwork.
- This creature is featured in most Jojojo Jokers printings.
- This creature is Joe Kirifuda's first Signature Card and the first created Jokers in the anime. It can say "There's no second chance to pull the trigger, one pull decides all!" (引き金は二度引かねぇ、一発が全てだ！, Hikigane wa nido hikane, Ippatsu ga Subete Da!), but does not seem to say anything else until very later on in Joe's Saga. This sentence actually came from the cowboy television show that Joe Kirifuda watched when he was young in VSRF.
- In its first appearance, it descended from the top of a cliff when summoned by Joe, while in future episodes it was airdropped by an aircraft.
- This is the first card in a major expansion that has 10000 power by itself.
- Zouny the Zony is based on this creature.
