Modern!Hades finds a stray puppy that he feeds everyday. The puppy comes to his house three times a day and Hades for the life of him can’t figure out how this small thing isn’t fat yet. This keeps happening for a while and he grows fond of the dog and names him Cerberus. But then one day, instead of eating, the puppy takes the food somewhere else so Hades decides to follow him. And lo and behold, he sees that there is not one, not two, but three identical puppies that he had been feeding this entire time. He adopts them all. Cause he already called the puppy Cerberus, he decides to call all of them Cerberus and every single time they respond together and move together like one doggy.
