Doc 'Guardian Slug'

Doc as a Guardian Slug

Guardian Slugs are ancient and powerful Slugs that have been specially trained by the Shadow Clan to energize the barriers that keep the Darkbane from entering SlugTerra.

Guardian Gates

Main article: Guardian Gate

Guardians Slugs energize the portal. When they are in their pedestals their element symbol appears above their head. For every element there's a Slug on a pedestal and once a Slug runs out of energy the symbol they represent will vanish from the portal.

  • Most slugs aspire to become guardians.
  • When slugs become guardians they gain new markings to show their new status.
  • Guardians can live for several years (centuries) making them the second oldest slugs after The Elementals. They're also the second most powerful slugs after the Elementals.
  • It only takes 4 elementals to power a gate, because they are the most powerful slugs
