He has quite an sadistic fondness for Ollamalitzli, the Meso-American ball game played by Tulio and Miguel. While a humble servant of the gods, Tzekel-Kan is otherwise very power-hungry, sadistic and bloodthirsty. He is also scheming and manipulative, and even psychotic. In his spare time, he plays with spiders.
