Kontiki is one of the names of the Inca creator deity Viracocha. (In the 1940s, it was used as the name of the Kon-Tiki expedition across the Pacific.)

Malkocoglu was likely picked up from a character in the Turkish TV series Muhtesem Yuzyil, which has become particularly popular in Chile (as El Sultán).
