He is a Healslime, a variant of the Slime monster from the series, who aspires to become a human, joining the warrior Ragnar McRyan in his quest to rescue kidnapped children from minions of Psaro.

He has been among the more popular companions and monsters in the Dragon Quest series, praised by critics for being cute and a reliable partner to Ragnar and cited as an example of moe aesthetic in gaming.

Additional praise has been given for how well he helps illustrate the mechanics of Dragon Quest IV due to his role as an AI-controlled support character.

In promotional media for the franchise, Healie is featured alongside the character Dragonlord in a live-action commercial for Dragon Quest Monsters: Super Light, where he is portrayed by Kanna Hashimoto.

[10] The Healslime, the species Healie belongs to, was first introduced in Dragon Quest II as a variant of the Slime race that has the ability to heal.

[19] Further praise came for the character's portrayal, with his human appearance in The Dark Prince becoming a hot topic on social media according to the staff of Den Fami Nico Gamer.

[4] Futabanet writer Amami discussed how intriguing Healie was as a character thanks to his dialogue, noting how significant the Party Chat feature added to the PlayStation was due to that.

[22] Dengeki Online staff appreciated the additional dialogue the Party Chat system produced for him, finding it cute and echoing the earlier moe comparison and feeling that he stood out among companion characters in Dragon Quest IV.
