The planet of Savanarr is enriched with a pure, unbreakable metal that can absorb, store, and redirect kinetic energy, called Nepodium. Many species on the planet were affected by the abundance of this metal, which eventually merged with all life. Infused with this metal, tribal civilizations sprung up across the planet, the most notable of which are the Machetidae, who thrived as valiant and prideful warriors, harnessing the Nepodium they possessed internally alongside that which they obtained from the planet's natural resources for tools and weapons. The tribes mine the Nepodium using their own blades; as the only thing capable of cutting through the metal, is the metal itself. It has since been used vast societies and technologies classified as Level 9.
- Ben scanned the DNA sample and transformed into a Machetidae during the road trip, when he helped the Machetidae tribe stop Fistrick and Vulkanus from poaching members of their tribe for their blades and mined Nepodium to sell as weapons.
- Kleaver's concept art and powers were inspired by Wolverine and Black Panther from Marvel Comics.
- Machetidae is a portmanteau of machete and rhinocerotidae (the zoological family of rhinoceros).
- Nepodium blades are equal in strength to Taydenite, the hardest mineral known in the galaxy.
- Kleaver speaks with an Australian accent.
