[[WMG: Marmaduke is the manifestation in our universe of one of the [[{{Main/CosmicHorrorStory}} Great Old Ones]]]]
* He appears as a ravenous, slavering beast, far larger than any natural dog.
* In many comics, it's clear he's just biding his time until he's ready to devour the souls of those near him.
* "Marmaduke" is just the nearest humans can come to pronouncing his true name, Mhrm'nndj'ukc.

[[WMG: Marmaduke is on some very good stuff.]]
Which likely has anti-aging effects.

[[WMG: Marmaduke's male owner is Adolf Hitler, trying to hide in the United States after World War II.]]
Just look at the guy!
