Human: Before being infected by the Spider Queen's venom, Syntax was originally an average human, and had black hair and wore a pair of lime-colored glasses. He also possessed a white labcoat along with an indigo and lime-colored shirt, and black pants.
Spider Demon: After being transformed into a Spider Demon, Syntax's skin and hair were changed into lavender and lime respectively, and grew four mechanical spider legs out of his back. His lab coat and lapels were also changed to black and lime respectively. He also possesses black VR goggles.
Unlike his appearance in the show, Syntax has a lanyard with an ID badge and five pockets on his lab coat, the mechanical spider legs on his back are used as extra hands instead of spider legs, and also has three eyes instead of two. He also has a purple cybernetic monocle.
Spider Queen: The Spider Queen is one of Syntax's allies, as well as his boss. At some point in time, Syntax was recruited by the Spider Queen to help her with the delivery systems for her robot spiders. In "Revenge of the Spider Queen", it was revealed that he often back talks at her. However, after he was corrupted by the Spider Queen's venom, Syntax became more loyal to the Spider Queen than he was before.
