First Evolution

As previously mentioned, a Chao is considered to be a child for the first three to five hours of its life. It then goes through a metamorphosis in a turqoise cocoon; this is called the first evolution.

Chao can evolve into three different alignments and five different ability types. This makes for a total of fifteen different possible first evolutions. In addition to this, there are three special evolutions, which are separately explained on the Chaos Chao page. You should already know how to control your Chao's alignment. This page will explain how to control its ability type, and will present the fifteen different first evolutions.

Please keep in mind that a chao will evolve into the alignment and ability type that it favours most at the very point it enters its cocoon. For this reason, you must maintain the Chao and keep it how you want it to be until it actually does evolve.

Ability Types

A Chao doesn't just evolve into a Hero, Dark, or Neutral alignment: it also evolves into one of five different ability types. These ability types are Swim, Fly, Run, Power, and Normal.

It is very commonly believed that a Chao evolves into the Swim, Fly, Run, or Power types if the corresponding stat is the highest, and that the Normal type is based on Stamina or a balance between the other four stats. All of this is completely false! Evolution is more complicated than that, and actually is not based on stats at all. Instead, it is based on a Chao's recent interaction with animals or Chaos Drives.

For example, you may have a Chao which is level 99 in the Fly stat and level 5 in all other stats. This does not mean in any way that it will evolve into the Fly type. Maybe it will, or maybe it won't; the stats tell us nothing. If the Chao was most recently given Fly animals, then it probably will evolve into the Fly type. However, if it was last given some Run animals, then it could well evolve into the Run type instead.

A Chao evolves into a Normal type if it has recently interacted with animals or Chaos Drives in a balanced way. Here are two examples to help explain this:

  1. You give your Chao 100 Run animals, then 100 Power animals, then 100 Fly animals, and then 100 Swim animals. You have given it an equal amount of every type, but only over a long period. Most recently, you have only given it a large amount of Swim animals. The Chao will evolve into the Swim type.
  2. You give your Chao 5 Run animals, then 5 Power animals, then 5 Fly animals, and then 5 Swim animals. You repeat this process 20 times, so that it has had a total of 100 of each kind. Because the Chao most recently interacted with a balance of all types, it will evolve into the Normal type.

The above explanation was just a summary of how it works. For more in-depth information on this, see the Gradual Evolution page.
