Stand (JOJO) power of Kira Yoshikage from JoJo No Kimyou Na Bouken Part 4. Typically manifests as a pink, vaguely cat-like humanoid with gloves and skull emblems.
Its primary ability involves charging objects with explosive energy. When somebody touches this "booby trap", the energy flows into their body and they are caused to explode from within. This ability can also simply detonate the charged object.
Combining its power with Nekogusa's Stand "Stray Cat", Killer Queen can create invisible air bombs.
Namesake is Queen (Band)'s song "Killer Queen".
