Philippines bio Official M-Net SurvivorSA: Philippines bio (May, 2018):
"No-nonsense Marthunis is a devout Christian and father of one from Durban. As a member of MENSA, Marthunis is intellectually nimble but admits that he struggles to read people and their emotions, so the social aspect of this game may pose a challenge for him.
Marthunis says that viewers can expect him to be 100% real at all times during this competition – but how seriously will the other castaways take this suit-wearing investment advisor?"
