Zenars, despite being large, are childish not only in looks but mentally too. For some strange reason, Zenars can only infect children between age two to sixteen with some exceptions. If no children are around, the Zenar will bring back older or younger people, going up or down each time. Zenars have a constant crave for fruits and flesh but they themselves don't need to eat or drink at all. Their cells don't need constant upkeep and if any are damaged, they are either healed or replaced faster than they can affect the Zenar. However, for some strange reason, the more intelligent the Zenar, the hunger they feel, and the more ravenous they get.
As mentioned before, Zenars have a craving for fruit and meat, mainly raw meat from animals. Zenars also love the taste of water, especially cold water. Despite having two rows of sharp teeth and many carnivores features, Zenars mostly satisfy their hunger with fruits, which the virus liquid cultivates. While some may be confused as to why Zenars mainly seem to eat fruit, it is something that we should all be grateful for because if the Zenars start hunting us, there won't be anything we can do about it.
