Scarab

Scarab

Introduction
The Scarab is a towering Covenant walker, upheld on four long mechanical legs - it is extremely different from the Covenant's other ground-based vehicles, such as the Wraith, Ghost, or Spectre. Although it may seem suited for combat, as seen in Halo 2 scenarios and cases in the series of halo books, the truth being it is actually for digging for things such as finding forerunner tech, or to create tunnels for military reasons. This explains the fact that it uses large mechanical legs instead of a Boosted Gravity Propulsion System like most other covenant vehicles. It is the largest known ground-based vehicle, as well as the most resistant to damage.
