ZYX like all of Tezar-Xil's forms are a part of his personality. ZYX being his anger, hate and overall disgust for life in general. The creature odd razor toothed smile was never explained and seems to contrast his grim and bleak theme. He was made in a fit of rage upon discovering his wife was kidnapped and this beast was formed.

ZYX possesses skin as hard as dark steel with fierce claws and horns. the skin can be described as very smooth or at stage 2 as jagged dragon scales. Recently he has suffered wounds that broke through his shell like skin and relieved his magma like flesh, which causes most physical contact with him to be fatal. His claws have an odd property to them that when even a tiny scratch is delivered the victim will suffer 35 forms of cancer like growths as well as severe legion rashes throughout the body, which reach peak infection in a mere week. Also Eight snake like tentacles slither out from his back each thirty five feet in length which he uses to throw himself around the area in a fury to confuse and prey on enemies.

ZYX's personality is fairly non-existent as he his built on anger and rage he often is driven insane from manic needs for violence and cruelty. On rare calm moments he has shown little to no intelligence often in the form of frequent zoning out or crazed mumbling in the Titan language. All other times he will hunt down any living creature he sees with no reason only to leave the body and hunt a new victim.

When Tezar-xil gained peace in his essence ZYX showed an increase in intelligence but the loss of his vigor. At this point he seems rather focused on very small and often irrelevant. With the calming he also seems to lay in the tall grass for days pondering but never really talking to anyone on his own thoughts.
