You can't put DTO in the breeding den because he contains the corrupt element which can't be bred. Likewise Dark Prime Chrono. There are also several other dragons that you can't put in the breeding den. For example Passion you can never breed, and his Parents Leftheart and Rightheart you can only breed sometimes during Valentine's day/week to obtain Passion. You can't breed the bomb and dynamite types and the food type neither. I guess the new Mystic type also can't be bred. We'll see.
