Sheer Heart Attack: An automatic sub-stand. Contained in Killer Queen's left hand. It's nigh-indestructible and will follow and attack the nearest heat source via explosion.
Another One Bites The Dust: After Kira was pierced by Stand Arrow for the second time he developed this sub-stand. Kira can tell the person his secrets and then place AOBTD in his body. It will live inside inside person's eye. If anyone tries to get information about Kira from that person, AOBTD will kill them (by destroying them on atomic level just like Killer Queen does). It can cause time loop where these people will die over and over again regardless if they ask about Kira again or not. Only Kira can cancel this time loop.
Stray Cat: A Stand of a cat which was hit by arrow. Can manipulate air to increase Killer Queen's range and power and give it more deadly attacks.
Invisible bomb: With a help of Stray Cat, Killer Queen can fire small invisible air bullets which will explode by Kira's command and can phase through defenses. Kira manipulates bullet's trajectory. Can also be used as a defensive barrier.
