Breeds (PS3 / 360)
There are many different breeds of Chao which can be obtained. When we talk about a Chao's breed, we are referring to its colour pattern, completely separate from and unrelated to its evolution. There are many factors (such as colour and tone) which combine to form the Chao's overall breed. This page will attempt to describe all these factors in detail.
Unfortunately, the PS3 and Xbox 360 versions of Sonic Adventure DX seem to have heavily modified the breeding system, with the changes being for the worst. We still do not know everything about these games work, as they were recently released and not much research has been done. However, it seems that many breeds have been removed from the game and made unobtainable.
A Normal Chao has multiple colours on its body. Those colours vary depending on the Chao's current alignment and evolution. The very first Chao that you start with is a Normal Chao, and this is why you can see it change colour depending on how you raise it.
It is recommended that you keep at least two of your initial Normal Chao for breeding purposes, and do not have them transform into Chaos Chao. This is because you cannot obtain any additional Normal Chao without breeding the ones you start with. This will be explained further on the Mating page.
You may hear people call this a Two-Tone Chao; that term indicates that the Chao has multiple tones or colours on its body. On other games, it is possible to get different colours of Two-Tone Chao. Unfortunately, it seems that the PS3 and Xbox 360 versions only include the Two-Tone Normal Chao.
A Coloured Chao has a single solid colour all over its body. You can purchase these as eggs from the Black Market. The available colours are: White, Red, Blue, Yellow, Pink, Purple, Aqua, Orange, Green, Brown, Grey, Light Green, and Black. You can find images of each colour in the Chao Gallery.
You may hear people call this a Mono-Tone Chao; that term indicates that the Chao only has a single colour on its body. On other games, it is possible to get a Mono-Tone Chao in the Normal colour, meaning that the Chao has a single colour which varies depending on its alignment and evolution. Unfortunately, it seems that the PS3 and Xbox 360 versions do not include the Mono-Tone Normal Chao.
Shiny Chao are similar to Coloured Chao. The difference is that they have a very bright shine over their bodies. They come in the same colours, and they can also be purchased as eggs from the Black Market.
On other games, it is possible to get Shiny Two-Tone Coloured Chao and Shiny Mono-Tone Normal Chao. Unfortunately, it seems that the PS3 and Xbox 360 versions do not include these breeds.
Jewel Chao are rare breeds of Chao which have a special jewel-like pattern to them; imagine a shiny, sparkling crystal. It is also commonly thought of as a metallic sheen. There are only two Jewel Chao available: Gold and Silver. The eggs are hidden in the Adventure Fields.
On other games, it is possible to get many more kinds of Jewel Chao: Ruby, Sapphire, Amethyst, Emerald, Garnet, Aquamarine, Peridot, Topaz, and Onyx; it is also possible to get Shiny Jewel Chao, which have strange and unusual appearances such as being transparent. Unfortunately, it seems that the PS3 and Xbox 360 versions do not include any of these.
