I am a bit of a chao nut so it seemed logical for me to make this! The
basic goal is to provide a quick refrence about the rare sorts of Chao in Sonic
Adventure 2:Battle. This list includes some breeding chao, black market chao and
a whole bunch of neat promotional chao. Whenever possible I will list how to obtain the
chao. Anyways here is the Table of Contents.
This is a list for only Sonic Adventure 2 BATTLE Chao
Immortal Chao
Tiny Chao Garden Chao Eggs
Black Market Chao Eggs
All S Chao
Breeding Chao
The Tails Chao in PSO!
Promotional Chao!
The Chao That Aren't
You've probably heard of these chao. They require a chao to love you enough to reincarnate, not once but TWICE!. However once you get them, these chao can not die! Any chao that can reincarnate can become an immortal chao so you don't have to worry about that :) Here are the steps to getting one.
Immortal Chao Instructions!
Inside of the tiny chao garden you recieve the option of buying chao eggs! These eggs almost resemble a jewel. Here is list of what you can find and for how much. Certain percantages are a bit off, but not by more than a quarter of one percent.
As you can see there are a lot of different chaos you can find. Not all chao cost the same and some are rarer than others. Topaz for example, is the rarest at .125% of the time. The other colors you can find at least 2% of the time
If you've been to the Black Market you probably saw the Eggs that they sell for you. These eggs come in 2 varieties.i Shiny and Non-Shiny. Non-Shiny are more common and if you breed (see Breeding Section you can make from Shiny Chao a whole lot! Anyways, here is a list of the Black Market Chao. Some of these chao need you to have more emblems then others.
If there shiny add an extra 0 to the end of the ring cost.
Have you ever been to the Chao Doctor with a chao and noticed how they
have a letter (A,B,C,D,E or S) next to there stat. This is there "rank".
The higher the "rank" the more the chao gains in the stat whenever he grows
a level. Chao that you recieve from the game and are first generation (not
children of 2 of your chao) have random rankings, which are almost never an
S rank. However when a chao metamorphisis they gain 1 rank (From E-D, D-C
and so on). This is determined by what they were fed earlier.
Red Animals/Chaos Drives = Power
Green = Run
Purple = Flying
Yellow = Swim
No/Mix Animals/Chaos Drives = Stamina
Other Colors = Semi-Random (if any stat (not stamina) is really high
its that one otherwise its Stamina)
When a chao is surrounded by an array of flowers that means it wants to breed. To breed find another chao (not a child) and place it in the flower patch. Unless the two chao dislike each other they will breed. A lone egg will be formed. This egg is a mix of the parents attributes. The egg has the following
Did you know that in Phantasy Star Online Episode 1 and 2 you can get a Tails Chao? Here is how!
The Tails is neat for seceral reasons, its stats are all level 1 and at 250 pts. each! In addition all of its ranks are A (which isn't shabby) and it looks cool
To date at japanese conventions Sonic Team has distributed some neat looking promotional chao. They are a Knuckles Chao, an Amy Chao, A strange Shadow and a strange Sonic chao. I have pictures of all of them.




Some chao can exsist but don't. It would be possible for you to have a chao that is an animal or looks like Omochao but so far these haven't been made. They might become possible one day but it doesn't seem like it will happen.
