What mythological beings did Apollo kill in revenge after Zeus struck down Asclepius?

Apollo's act of revenge was directed at the Cyclopes, who were responsible for forging the thunderbolts that Zeus used to defeat Asclepius. When Asclepius, the god of medicine, attempted to bring the dead back to life, Zeus struck him down to maintain the balance of life and death. Furious at the loss of his son, Apollo killed the Cyclopes as retribution, which exemplifies the way in which divine relationships and familial ties often play a crucial role in Greek mythology. The Cyclopes, with their association to fire and craftsmanship, directly linked to Zeus's power, make them a significant target for Apollo's wrath. The other options do not have a direct connection to this specific narrative of revenge, as Titans and Giants are generally associated with other mythological events, while Nymphs are typically seen as benevolent nature spirits rather than beings involved in the conflict between Apollo and Zeus.
