Immortality is a power and/or ability that enables a living being to continue to live for an indefinite period of time, free from old age, disease, or any other cause of natural death. However, this does not mean that "immoratals" cannot be killed; it simply takes different means of killing them.

The Guardians of the Universe, the Entity, and the seven Emotional Entities are all immortal, although for different reasons. The emotional entities are immortal because they are the living embodiments of seven particular emotions; as long as those emotions exist, the entities will continue to exist.
