What mythical creature can kill a Phoenix?

In mythology, the only creature known to be capable of killing a Phoenix is the dragon, particularly in stories where dragons possess immense power or magical abilities. While the Phoenix is associated with rebirth and immortality, dragons are often depicted as formidable adversaries with the strength to challenge even the most resilient beings. However, the nature of these encounters varies across different mythologies, and the Phoenix's ability to rise from its ashes typically ensures its survival.
