The Cuddly Killer

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

The adorable creature with a deadly or 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 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 Brains isn't fooled by the Cuddly Killer and tries to warn their friends about its evilness, but they all call them the Psycho 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 Brains, as we all knew would happen, will be proven right as the Cuddly Killer turns against its fooled caretakers in an attempt to end their lives with whatever means it has at its disposal.
