Zarkt

Zarkt is an evil being who has no empathy towards his enemies like the rest of the Forbidden Five, such as when he and the others mockingly laughed at Zarkar, who was emotionally shocked after losing the majority of his tribe to them and their destructive power.

While being in the Nether-Space, he was shown to get easily frustrated, being the only trapped member who complained to Nokt and Rox's soul and then ordering the two to hurry and find a way to free him and the others during their exile. This is further proven when he shoved Kur during an argument over being patient for their release. However, when he heard rocks moving, he went to check the location but in his arrogance, he didn't bother to see Bonzle and Kai. Also, when he realized Sora was pretending to be unable to hear him after he failed to get the Prismatic Blade, he left with a growl. His frustration also made him impatient when looking for the blue Prismatic Blade with the Dragonians, grabbing Tyr's collar and ordering him to hurry. When telling Rox of his failure, Zarkt remained calm when he tried to explain what happened but was ignored.

Like Thunderfang and the rest of the Five, Zarkt also has a sense of entitlement, such as when he backed his claim that everything they desire belongs to them by right of conquest. He is also very power-hungry, desiring the extra power Thunderfang had promised them once the Five free him.
