Buy the black egg from the shop in the Tiny Chao Garden on Sonic Advance, SA II, Sonic Pinball, and SA III for 20,000 rings. Then send it to SA2 with the GC/GBA cable.
Even though I haven't heard of a "Onyx" Chao, I believe it might be a form of a Jewel Chao, or possibly a Shiny Chao.
SA2 is for the Dreamcast, while SA2B is for the GameCube. SA2 has Big cameos in the level, SA2B does not.(SA2B only has cut scene cameos but so does SA2.) SA2B has more 2 player stages than SA2. SA2 allows you to put your chao in the VMU, SA2B allows you to put your chao in the Tiny Chao Garden. SA2B has Chao Karate. some chao world structure is different.(dark garden is TOTALLY different.) There are more.
it can be a chaos chao
Hmmm...your opinion can depend on your question.You can make these Chao listed below and see which one you think looks super cool and is Hero Type: 1.Streamline Chao: A Streamline Chao is a Hero/Swim Chao.You make your Chao white when it's a baby and give it swim animals.Before it grows,it should have yellow markings on its body. http://chao.hippotank.com/sa2/images/evolution/hero/swimnone.jpg 2.Sky Chao: A Sky Chao is a Hero/Fly Chao.You make your Chao white when it's a baby and give it fly animals.Before it grows,it should have purple markings on its body. http://chao.hippotank.com/sa2/images/evolution/basic/herofly.jpg 3.Hero Run Chao: A Hero Run Chao is a Hero/Run Chao.You make your Chao white when it's a baby and give it run animals.Before it grows,it should have green markings on its body. http://chao.hippotank.com/sa2/images/evolution/basic/herorun.jpg 4.Energy Chao: An Energy Chao is a Hero/Power Chao.You make your Chao white when it's a baby and give it power animals.Before it grows,it should have red markings on its body. http://chao.hippotank.com/sa2/images/evolution/basic/heropower.jpg 5.Angel Chao: An Angel Chao is a Hero Chaos Chao.Reincarnate your Chao 2 or more times and give it one of each animal in the game.When it grows,it should be the Chao in the link below.This Chao is only available in Sonic Adventure 2 Battle.It doesn't matter what your Chao's previous evolutions were.There are 21 animals in the game. http://chao.hippotank.com/sa2/images/evolution/chaos/angel.jpg
No They are only on SA2B or SA2
These are very rare chao that are immortal and never die. Get any chao and reincarnate it twice. Feed it one of every 21 animals. No chaos drives!!!!!!!!!!!! When it evoles, it will be a chaos chao!
It is a angel chao.
No it will never die or reincarnate once it is a chaos chao.
this website has all of the chao evolution pics http://chao.hippotank.com/sa2/
But you can't before it is
Yes, it can like as many people as it wants but pet it a lot with hero char. if you want an angel chaos chao and the opposite with if you want a dark chaos chao. or use both to make nuetal (light chaos chao)
