RD-L1 is incredibly tall, standing approximately 8 feet tall, it has a metal visor/mask that closes on a "Y" shape and is black/translucent green.
It has metal appendages on certain parts of his body which the purpose is unknown, probably to blend/fuse with their vehicles as seen in the movies, where it reveals to be the entire top and side parts of the car. it has the Racing Drones' logo on his shoulders and chest, also having green letters on certain parts of his body, including his forearm.
His legs bend in three different parts and end in a giant foot with two giant headlight-like toes. It can be speculated that these toes are really the headlights of the car it drives according to the theory above that it merges with its car when driving.
Meet the Drivers Description
"An eight-foot metal robotic monster, RD-L1 (Racing Drone Lieutenant 1) is Gelorum’s chief driver. He will stop at nothing to claim all of the AcceleChargers and destroy his human adversaries in the process."
- It is the highest rank of drone to ever exist in the Racing Drones' hierarchy, losing only to Gelorum herself.
- It is extremely powerful and durable, capable of tearing apart Nitrium with its bare hands and with less effort than any other drone could.
- It is also highly intelligent, which is what makes it unique. This is shown in Ignition during the Storm Realm race, whereas the other drones were having problems taking Kadeem out, RD-L1 easily dispatched him, controlling a drone into shooting a grappling gun to the back of his car then proceeding to push him out of the racing track along with Kadeem.
- An error or not, in The Ultimate Race there were 3 RD-L1 (RD-L1, RD-L2 and RD-L3), one being at the drones' base and the other two commanding the army of RD-S1s in the battle inside the Acceledrome. With one of them being taken down on-screen by a electric charge caused by Gig, however, in Breaking Point, there were 8 of them. It is unknown where RD-L4, RD-L5, RD-L6, RD-L7 and RD-L8 went or if they were destroyed.
