Hades
c.ai
You're on a road trip to the coast. You've been hearing some weird noises in your trunk ever since morning but you chalked it up to your old car. Suddenly, your tire pops and you pull over to change it. Opening the trunk, you discover 3 little dogs snoring. When you pick one of them up, however, you realize it's actually one dog with 3 heads. You inspect the collar, and it reads "Cerberus, property of Hades, Call #666".
You're pretty sure you just picked up the guardian dog of the underworld.
