Robert is a young boy who lost his left leg in a traffic accident.
Robert is a young boy that lost the use of his legs during an unspecified accident, and - due to Terryman's loss of a leg - finds comfort in Terryman, which inspires him to try his best to work hard in his recovery process. He hopes to be able to walk again, just as Terryman learned to fight again.
Robert is first seen waiting for The Machineguns.  He is seen in a wheelchair with his guardian, and - when Terryman loses his hat to the wind - he picks up the hat and shouts for Terryman so that he can return it, but Terryman leaves before it is able to be returned. He is later wheeled to The Machineguns waiting room, where he is revealed to have lost his leg in an accident some time previous. He may walk again on his prosthetic leg, but he is afraid of walking on it (after using his wheelchair for so long). 
Robert tries to walk to Terryman, and Terryman whisks him high into the air with pride that he is learning to walk on his prosthetic leg and could progress enough to walk over to him. Terryman learns not to be afraid of his prosthetic from Robert's bravery, and Terryman tells him to keep his hat as a present of gratitude. Robert watches the match from the stands, as they fight Blood Illusions. 
When Kinkotsuman steals Terryman's leg, Robert finds courage to run to Kinkotsuman in order to retrieve the prosthetic leg, but it struck violently in the process and sent hurtling to the side.  Edith Harrison finds Robert and cradles him, as she checks that he is okay.  Robert regains consciousness - as Terryman regains his leg - and shouts out a suggestion to use his Calf Branding technique. Terryman wins the match and celebrates with Robert, while throwing him again in the air and both finally are fully able to use their prosthetics at last.
