How many main villains you think the current OG 6 ninja could stop?

I was rewatching rise of the snakes and it made me think of how many people the Ninja have had to face but also how many main villains the current OG 6 in dragons rising could defeat with and without Draconus Form I'll give my thoughts and explanations for each one. By the way it'll take place in the same location where the battle was fought. S1- The Great Devourer- Yes Low Diff(No Draconus) One of the RDT Ninja can just fly into it's weak spot. S2- The overlord/Possessed Garmadon Yes...
