Guardian

A Guardian is the manifestation of the soul from what is referred to as a "Guardian user." A Guardian can only be seen by other Guardian users, or even those who don't have one, but qualify such as family. These beings are what have been described as the Guardian Angels from stories, though their origin is unknown. Guardians are usually awakened during times of trouble. The Guardians are sustained to their users, meaning any damage they take is inflicted onto the user as well. If a Guardian were to die, so would the user. However, if vice versa, the Guardian could help regenerate the user by massaging the user's heart or closing up any wounds.

In the Smurf Me Up series, Angelo Smurfling is the first character revealed to have a guardian, whom everyone at first believed to be an imaginary friend. Alchemist Smurf is the second character revealed to have a Guardian as well.
