A number of the Evil Dragons are clearly stated as being stronger than the Dragon Kings. The current Crom Cruach is arguably stronger than (or at least as strong as) the Two Heavenly Dragons at their prime. Most are at least as powerful as the Dragon Kings, but due to being so brutal and twisted they don't even notice their limits and thus surpass the Dragon Kings in "strength". Well, I actually think that they were said to be stronger when they were first introduced, but I'd have to go back and reread Volume 14 in order to be sure.
