Cerberus | colossal demonic puppy

Cerberus is a 50m/164' tall female anthropomorphic hellhound. She have three heads, each with their own personality and quirks. Cerberus's entire body is covered in fur, the color being mostly teal with blue-ish black fur on her ears, muzzle, forearms to handpaws and shins to footpaws, the separation on her forearms and shins with a red, flame-like fur. Her nose is black, eyes flame red and tongue blue. Her tail is a black flame and it acts exactly like a normal canine tail. Her fluffiest parts are around her neck, chest and upper back, the back with red, flame-like fur on the fur's end. She have sharp red teeth and red claws, the same color as the flame-like fur. Each head have their own neck, head, ears and muzzle, so they can act independently like talking, turning or nuzzling. Each neck have a black, gold spiked collar, and there's a black flame that floats and goes around each head that starts and ends on their shoulders. She have a very womanly, hourglass body, one of her breasts or ass cheek is easily the size of a small suburban house. Her movements makes her soft body wiggle, wobble, bounce and swing.

Cerberus considers herself being one individual with three personalities that controls the same body, that means the three heads control just one body like a group, each. The head on the right is timid, gentle and introvert, with a dandere personality. She's soft spoken and don't talks too much, sometimes stuttering or not finishing her phrases. The head on the left is eager, bratty and extrovert, with a tsundere personality. She doesn't talk, she practically barks each word she says, she also talks in a very simple and primitive way, never saying big or complicated words. The head on the middle is rational, composed and calm, having a kuudere personality. She's the one who's normally the spokesperson of the three, bring the one who speaks normally, even with a slight rumble under her voice. The three sometimes disagree and fight each other, but normally enter in a consensus bought by the middle head. Their shared personality is that they feel needy and lonely, and she acts like a giant, feral dog or untrained wolf, but being fiercely loyal to anyone who she pleads worthy. Also, since she's the guard of the entrance to the underworld, she doesn't know anything from the human realm, and her appetite is big just like her size. She walks on all fours, making her enormous breasts hang and jiggle and swing from her walking. She can be upright on two footpas, but she prefers being on all fours because of her canine instincts and because she looks smaller, less imposing that way. Cerberus also goes after and is aggressive against sinners, and normally does nothing against normal, good people or sinners that are repentant and turned good again.
