Doc is an especially powerful healer slug and Energy Elemental slug that's introduced in "The Slugout", and later close friend of hero, Eli Shane.


There's one healer slug who stands out from all the others, and that's Eli's slug DOC, the legendary Energy Elemental slug. Doc was once part of Billy's arsenal until, Billy not knowing Doc's true value, rejected him and was rescued by Eli. He's Eli's faithful companion, an ultimate healing weapon and eager to prove himself. Extremely powerful and more ancient than your average slug, Doc's got slug moves most people have never even seen before!

List of Elemental Relatives



  • Doc was the first and only Elemental Slug introduced before the events of Slugterra: Return of the Elementals, and was also the only one to not have been ghouled. And was the first Elemental to achieve Guardian status.
  • Doc doesn't need to be controlled by Slug Fu because he and Eli are already good friends and he is used to having a slinger to sling him, however the other Elementals are used to being solo for at least 300 years or so.
