Design.
The visual appearance of Chitti was based on the G.I. Joe action figures. For Chitti's 2.0 version look, its hair was spiked and brown coloured lenses were used for its eyes, whereas for its "good robot" look, green coloured lenses were used. The wig used for Chitti's 2.0 look had a silver streak in the middle, made out of Yak hair, while its leather jacket was designed by Vogt. To make Vaseegaran look mature, the team made Rajinikanth sport an Oakley beard. Suits made of copper were used for Chitti's costumes.
