RD-L1 stands at approximately 8 feet tall. His face is metallic, and has a Y-shaped green visor that can appear over his eyes.
His body is a jet black metal material, with various metal appendages and green tubes. Windshields are attached to his shoulders, blending in with the Racing Drones vehicles. He has green Racing Drones code across his torso and and wrists. His emblem is displayed prominently on his chest and on both his shoulders.
His legs bend in three different parts and end in a giant foot with two giant toes similar in style to headlights.
As the second-in-command, RD-L1 is loyal and follows Gelorum’s orders with the utmost precision.
"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.
