The Tread Assault was a large 4x4 used by Cole. It resembles a big black 4x4 vehicle with elements corresponding to Earth. The Tread Assault can be summoned by focusing one's mind on a weapon (in Cole's case, the Scythe of Quakes).
After Wu told the Ninja they are capable of using their Golden Weapons as vehicles, Cole summoned the Tread Assault to retrieve the Fangpyre Staff for the anti-venom. However, they all lost control of their vehicles and are unable to summon them again.
- This is the only Golden Weapon vehicle to have a shooter in the Season 1 sets.
- It is the only Golden Weapon vehicle to not be remade in the Legacy set wave.
