This Slug is exactly what its name says it is: a boon. In normal duels, this Slug is of little use, since its move set is so heavily geared towards dealing with Ghouls. However, in the approximately five years that Dr. Blakk kept SlugTerra in fear of his Ghouls, there were few better Slugs a Slinger could have in their arsenal.
Outside of deflecting and curing Ghouls, Boon Docs are also highly effective against Neotox Slugs, able to neutralize the worst of their attacks by using Lightshield on their Slinger and fellow Slugs.
The Boon Doc makes an excellent partner Slug for those in the medical field, as well as those who spend a lot of time working with young children.
- Since Billy of The Hooligang did not know what Doc was at first, it can be assumed that only people who are particularly knowledgeable about Slug species know what Boon Docs are.
- The fact that Boon Docs are so rare can explain this, since they are not common Slugs.
- Some of the Boon Doc's concept art designs are now the current designs of the Lariat and Phosphoro.
- Boon Docs are the only slugs that have legs when they transform.
- A Boon Doc slug can get overworked when there's too much Dark Water for them to neutralize at once - due to the high concentration of Dark Energy.
