# Characters
There are only 10,000 Kodas
## Kodas
Kodas are the main characters of Otherside.\
They use **Soma** to create forms and **Chaos** to take them away.\
If someone owns a Koda, they can play as that Koda.
In the Resource game, Kodas have special uses that gives players advantages.
## Voyagers
Kodas create Voyagers out of **Soma** or **Chaos**. They are the exoskeletons for these two forces, enabling them to move around and explore Otherside.
Soon, these Voyager exoskeletons will be upgraded to be customizable exoskeletons for Soma and Chaos.
## Custom Characters
In the world of Otherside, Kodas and Voyagers work together so that people can bring in their own characters and build their own worlds.
In this documentation, we'll sometimes refer to Custom Characters as Third Party Avatars (not created by Yuga Labs or one of its partners).
In the mainline Otherside experience, the use of custom characters must be unlocked.
In the ODK experiences, all custom characters are available to experience designers. While experience designers may place some limits, the core technology is designed for **maximum interoperability**.
