How do you make a neutral Knuckles Chao in Sonic Adventure 2 Battle?

Answer 1

To get a neutral chaos chao in SA2B, your chao must have been reborn twice. You get them reborn by treating and training them well throughout their lives until they die. When they do die, a cocoon will appear around them and if they are going to be reborn into an egg, the cocoon will be pink. If the chao is going to die and not come back, the cocoon will become grey.

So, once your chao has been reborn twice (you'll need to get it reborn after the first time), you have to feed it one of every animal AND NO CHAOS DRIVES. Then you feed it either a dark fruit, a hero fruit or a chao fruit depending on what you want it to be (in your case you feed it a chao fruit) and then wait until it evolves. If you've done it correctly, you'll have yourself a neutral chaos chao.

Answer 2

You can't.Knuckles Chao never existed in the U.S.A version of SA2B.They only existed in Tokyo,Japan.But,the only way you can get a Knuckles Chao is by via hacking.
