Hatch a normal egg, and raise its Run level by a lot, like 50, or even 99.
The spikes grow on the back of its head when you raise the Run, and eventually, if you level it enough, it should start to turn blue.
this is how i did it i traded my chao from sonic dx to another chao from sonic advance 2 for the GBA then i traded that same chao to my one of my chao in sonic 2 battle
You need to have a regular chao to get a sonic chao on Sonic Adventure DX. Before your regular chao evolves to a neutral chao, you need to give it a lot of speed. As it evolves to green, give it more speed so it turns blue.

Yes they are.

get a blue chao and make it a neutral run type
buy a golden chao then make it run type.
monotone chaos are the chao that you buy from the black market
You Can In Sonic Adventure 2 Battle. I Think you can in DX.
