Black Dragons

Here is the list: Part 1 - yes, he is strong there (although he is still purple there, but that's not the main point). Part 2 - yes, and again strong (it seems that there were red and black ones there). Part 3 - no, they are in 3rd place among the strongest creatures, archangels are in 2nd place, and titans are in 1st place (because the maximum damage of titans is 60, and archangels is 50). Part 4 - yes, although the competition is again among archangels, titans, monsters, and firebirds. Part 5 - no, they are in 4th place (lava dragon is in 3rd place, red dragons are in 2nd place, and archangels are in 1st place). Part 6 - I haven't played it, but I think they are strong there.
