Furthermore, Kira cannot use the ability on himself, akin to how Josuke cannot use his Crazy Diamond to heal himself.

Using Bites the Dust forcibly prevents Kira from summoning Killer Queen because the host of Bites the Dust is harboring it he must deactivate Bites the Dust and withdraw Killer Queen if he needs to defend himself.

It doesn't activate when Josuke overhears Kira revealing his identity himself. Hayato deduces that Bites the Dust can only become the host of non-Stand users, as Kira can only tell a non-Stand user his secrets to enable the ability. The bomb can detonate multiple people in the vicinity simultaneously if they discover Kira's secrets from the host. When this happens, a miniature Killer Queen enters the eye of the person and causes an explosion, killing them. When planted in Hayato, it automatically activates when Kira's identity is revealed audibly or through writing, as well as when someone questions Hayato about anything related to Kira. Bites the Dust acts independently of Kira's will. When someone learns of Kira's secrets, Killer Queen is separated from Kira and planted into their body, making them the Stand's host.

It is born from Kira's desire to prevent anyone from knowing his true identity, as well as his desperation following his impulsive murder of Hayato Kawajiri. Yoshikage Kira is granted this ability when Yoshihiro Kira's Stand-creating Arrow pierces him a second time.

Bites the Dust detaches itself from Kira's right hand, similar to how Sheer Heart Attack detaches itself from Kira's left hand. Killer Queen Bites the Dust takes the form of a miniaturized Killer Queen.
