No? Once a chao has reincarnated twice and reached the state of being a Chaos Chao they simply... never die.
Chaos die at age 5 but the better you treat it the longer it lives and it will be reborn. If you treat it badly it dies quickly without a trace.
Chaos Chao is available if you give your chao all the animals that you can get in stages whether there going to be a hero or dark chao if you do these they will change to a chaos chao which in this form can never die and it won't turn into a baby but the looks of your chao will not show any animals and it can't mate and if your chao has any expressions on its face smiley or anything else it will NOT show on your chao anymore but its worth getting. By the way to get the ultimate chao you have to do those steps in sonic dx.
