Sporty from the Krazy gang was black, and a positive role model, liking his sports and all that.
Freaky , from the same gang, was green ( being an alien), but they phased him out after a bit, because I don't think they knew what to do with him/ it.
Cheeky had a couple of racist stereotype mates like the Indian lad Gunga Jim ( " Oh, curry curry, hot stuff!" " Groan! They ought TURBAN jokes like that one!"), but that was from his spin- off comic Cheeky Weekly.
