Cave Trolls are a species native to SlugTerra. According to Will Shane, you can't find anyone more loyal or trustworthy than a Cave Troll. Cave Trolls are noted for being great engineers and are credited for creating most of the passage ways used in SlugTerra. In addition, Cave Trolls also controlled the Great Western Mecha Forge that produces Mecha-Beasts.
It is implied in "The World Beneath Our Feet Part 1" that Cave Trolls are not popular with other species. Both Trixie and Burpy are initially afraid of him, and Kord believes that Eli won't want to duel with him because he's a troll however Eli didn't seem afraid anyway.
