In some lore, a God named Bahamut exists. He's generally a good guy. He occasionally goes on strolls through the material planes in the disguise of an old man. He takes his posse of 7 Ancient Gold Dragons with him in the form of 7 Canaries.

People pick on the old man because it's just an old man with some birds. Then the old man unfolds into what is arguably THE good God in a lot of DnD lore (or at least the primary good God) with 7 immensely powerful creatures that start maxing out the challenge ratings.

The likelihood of surviving this encounter are very very very very slim. People talk about terrasques all the time. Giant mountain sized monsters but no. This is how you get annihilated.
