ARC Survey: 023

We all know how many Xeros use the unique produce on OWAI-6 to gain new interesting traits but what else do they use it for? Some fruits are used for cooking, dyes, even knitting needles! How does your Xero use the special flora around our beautiful world?

What is a Xero?

Xero Info Subspecies Traits

A Xero - pronounced like ‘Zero’ - is a species of alien experiments that are ‘rebuilt’ from the species’ original DNA, combined with the DNA of other creatures from across the galaxy! There are several subspecies of Xero, each with unique features and traits.

To add a Xero to our Database, you can either adopt one from one of our Geneticists or earn Prestige and collect Wish Shards through the game to make your own Xero.

While owning a Xero is not required to participate in the game or enjoy the species, lets be real; it's probably why you're here! There are a few different ways to get your paws on one, including options that are completely free! The Project Xero community prides itself in being extremely welcoming to new members, and we have special affordable sales nearly every month for those who do not yet have their own Xero.


Official Xeros

Xeros can be purchased from NeonSlushie or other official Guest Artists when new ones are put up for sale! We will also occasionally run raffles or other events that you can participate in for a chance to win a free Xero!

Our Discord is the best way to stay notified of any official sales. We sometimes sell them here on the site too!

Trade for a Xero

Members may sometimes trade their Xeros for other Xeros, other characters, art, and more!

Xeros can be listed as UFT (Up For Trade) on the Masterlist, and you can bookmark your favorite Xeros to get a site notification if they're UFT! Trades between members occur most frequently in our Discord server.
