There is a theory from the late fourth century that the etymology of the Cerberus comes from the greek creoboros, which means “flesh-devouring.” Though not accepted by all scholars, I like the savagery of this naming convention: slapping the most directly relevant name possible onto the creature so that you cannot possibly miss what this thing is all about.
In the legend, the dogs are one beast; the heads are not distinguished with personalities. In Seattle, two of the heads always garnered more attention. Danny Hultzen and Taijuan Walker were always the strongest heads of Seattle’s Cerberus; both the first Mariner selected in their draft, one with the highest floor (all together now: there is no floor) and one with the tantalizing athletic ability to pump gas and slam dunks.
