Yes.
Give it a heart fruit
In Sonic Adventure 2 battle a chao that looks like sonic would be neutral/running/running you could give it chao fruit just as long as the skill with the highest level is running for both evolutionary cycles.
This may not work but try this with a newborn chao.Always see that chao with Sonic.Give it chaos drives and animals then help with run.And feed it fruit everyday.If this doesn`t work,keep looking for answers.
To make a chaos breed you have to give the chaos that you want breed heart fruits.
make it chaos chao and give it a dark fruit......easy huh???^_^
Buy it at the Black Market.
Get rings and hopefully you will get it
what you do is just increase your chaos fruit level by stamina until it reaches 12 after that take it to the doctors and then just wait till it evolves in hero or dark or neutral chao bye by tyler pearce morecambe 13
Give each chao a heart fruit (buyable at the black market) and wait for them to have flowers around them. It may take a few heart fruit to get flowers but when you do, you set them next to each other.
you have to give the seed to a chao that likes the fruit it likes then it will pick a spot where you can use a seed waterer toplant it
Buy heart fruit and give it to your chao and he will mate
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.
