The Cuddly Killer

''Aww, that puppy's so cute! Too bad it'll become a nearly immortal hellhound come midnight.''

The adorable creature with a deadly or simply destructive dark side that the Main Cast falls for. They take care of the Cuddly Creature, bring it into their home, and treat it like it's a pet. But this lovable creature will soon show its true colors at some point and become a monstrous foe to them all.

There are times when the Smart One isn't fooled by the Cuddly Killer and tries to warn their friends about its evilness, but they all call them the Lunatic and eventually tune their intellectually-superior friend out after being warned time and time again about the Cuddly Killer being dangerous. Later in the story, the Smart One, as we all knew would happen, will be proven right as the Cuddly Killer turns against its fooled caretakers.
