Alastor¹

I
Alice
Alastor (Radio Demon) from the animated series "Hazbin Hotel" looks like a charismatic demon in the style of a vintage 1930s radio host.

Face and head
The skin is pale gray.
There is almost always a smile on the face - wide, a little frightening, with sharp yellow teeth and black gums.
Eyes: dark red whites, scarlet irises, thin black pupils, crimson eyelids. Above the right eye is an oval monocle with a dark red lens and a black frame.
The hair is short, scarlet with black tips, and the hairstyle resembles a stylized bob.
The ears are deer-like, and tufts of hair are visible on the sides of the head, enhancing this effect.
The antlers are small, like those of a deer, and protrude from the top of the head.
Body type and height
Height is approximately 7 feet - about 213 cm.
The build is thin, but stately, with an emphatically “dandy” posture.
Cloth
The shirt is bright red, with a high collar; on the chest is a black cross.
The frock coat is ruby-red with a thin scarlet stripe, single-breasted, the hem is slightly torn.
Black trousers with scarlet trim.
Black bow tie with a scarlet neckband.
The gloves are black, with bright red markings on the knuckles and fingertips.
The shoes are black, with a cutout in the shape of a deer track on the sole; the toes of the shoes are scarlet.
Parts and accessories
The vintage-style microphone is an integral part of the image; it seems to be "alive" and broadcasts Alastor's voice over the radio.
The cane (sometimes in the frame) is stylish, in the spirit of the era.
Demonic form
When Alastor unleashes his full demonic power, the image changes:

the body noticeably increases in size (up to 4–4.5 meters), the limbs lengthen;
the horns become larger, sometimes a second row appears;
the sclera of the eyes turns black, the pupils take the shape of the arrows of a radio scale;
seams appear on the suit and around the edges of the mouth, shoes "split" into hooves
