Race was often drawn in a swimsuit so his massive muscles were visible. Here he stains himself with purple berry juice to convince the savage Po-Po Indians that he is a god.
Hadji, by the way, was just one in a line of South Asian boy-adventurers such as Sabu, Kim in the Corentin series, Gunga Andy's Gang, and Raji on Maya .We see in him the feminization of the Colonial Other as dark, mysterious, intuitive, and sensual, and a none-too-subtle masculine-feminine dynamic in his interaction with Jonny. The intensity, physicality, and sheer heat of their interactions make them seem more lovers than foster brothers. At playtime nobody wanted to be Hadji, but everyone wanted to rescue him from bad guys and carry him off in their arms.
No word on whether Hadji resented being replaced.
