This is RD-L1's primary ride up until Speed of Silence. Easily confused with RD-L1's other vehicle (RD-05) you can tell this one by its pointed wheel wells. Despite being replaced later, this one is still one monster SUV with its forward-mounted cannon and deployable slam ram hyperpod built-in. RD-08's body is shared in part with RD-L1.
RD-08 was destroyed in the Swamp Realm. It was also seen driving off the track in the Cavern Realm - it's unclear if the vehicle was recovered or rebuilt before the Lava Realm.
