I've been thinking that hydras are overpowered. Take a 12 header. Add the regrowing heads part. Add cyro or pyro. A hydra that regrows heads can have up yo double the original number of heads. Pyro and Cyro give it a breath weapon at 3d6 per head. So 24 heads time 3d6 equals 72d6 breath weapon.

All that in a CR14 or so. CR24 dragons don't have a breath weapon that good. They do have a higher DC check on the save and better abilities overall but still.
