Slugterra

Set in a luminous, high-tech underground world beneath the Earth's surface known as Slugterra, the series follows Eli Shane, a fifteen-year-old determined to become the greatest Slugslinging hero of them all. Alongside his loyal companions—Pronto the tracker, Trixie the surface-born videographer, and Kord Zane, a heavy-lifting cave troll—Eli explores the 99 caverns, collects and trains various species of living ammunition called Slugs, and battles evil forces. Their primary adversary is Dr. Thaddeus Blakk, a ruthless slinger who aims to ghoul the magical slugs and conquer Slugterra. Throughout their adventures, Eli must live up to the legacy of his missing father, Will Shane, while uncovering secrets about the dark history of Slugterra. As the series progresses, the gang faces escalating threats, ranging from corrupted ghouled slugs and dark slinger syndicates to ancient evil entities threatening the very balance of the subterranean realm. Through courage, friendship, and clever tactical use of his slugs' unique transformations, Eli fights to keep Slugterra safe.
