Role in the series
Master Zik is the wisest of the Deadly Six, serving as a source of wisdom for his student Zavok and others. He is very perceptive and has an eye for seeing potential in others.
Normally, Master Zik takes it easy in his semi-retirement. He is most of the time very calm and in a state of peace, telling Zavok calmly not be concerned when he asked Master Zik not trouble himself with Sonic and being impressed by Sonic despite him being a threat to them. Likewise, he never shows any sign of distress or surprise and is never fazed by insults or taunts. Despite the air of peace around him though, Master Zik can be very firm. He has no problem about stepping into a situation to handle it himself where others cannot and he can be very strict and grimly serious when the situation calls for it. He also does not tolerate disrespect, telling Sonic repeatedly that he needs to learn respect.
Master Zik is extremely confident in the wisdom granted him by his advanced age, believing it can always triumph over strength, and looks down upon younger, less-traveled people in general, thinking youth is truly wasted on them. Regardless, he does take a certain liking those that can impress him as he smiled after seeing Sonic's fighting skills. He also thinks highly of his student Zavok, believing that Zavok would eventually come up with the same idea he had for turning Sonic into a robot slave.
Like the other members of the Deadly Six, Master Zik is inherently malicious, sadistic and violent. An omnicidal monster, he takes a leveled joy in inflicting pain, torturing and killing others, and has no qualms about causing global genocide for his own gain. He will also gladly encourage others' genocidal ambitions, praising Zavok for his plan to destroy the world. He also comes off as vengeful, given that once he was freed from Eggman's enslavement, Master Zik launched an attack on the scientist.
