No, not all chaos do, but it is possible to have a chao evolve so that it resembles Sonic by having it first evolve to a running-type hero chao, then have a second transformation again as running type.
If you mean a hero chao,pet it with a hero character while it's a baby until it turns white with blue highlights and emotiball. Then wait for evo. If you mean the Hero Chaos chao ask again.
it takes a little while for chao to get older but you have to care for it and after a while(depending on which character you use hero or evil)then the chao will go to the stage of chao death.
You've gotta unlock both Hero and Dark Gardens.
Get a green, pink, or normal chao. Balance with both hero and dark characters to care for it. Give it only purple fly chaos drives and red power chaos drives. When it evolves, it will be an elf chao!
