Personality -
Suppressed Form: In his suppressed form, he pretends to be vain, but anyone who isn't an idiot can see that he really is insecure and hates himself quite a lot. He is so socially awkward that he's actually cool. He is a very ice-cold character, frigid-blooded, so to speak, caring little about what most think. He has a desire to please those he deems worthy. Another thing about Samaeal is that he is rather sophisticated, and manipulative, and often mischieviously playful. He rarely smiles, except in a mocking or playful leer.
True-Form: He retains his simpering-but-actually-hates-himself qualities, but only to an extent. Hot-headed, yet cold-blooded, he trades in his manipulative sophistication for savage brutality, becoming much more masochistic and sadistic, and waaay more morbid, and relies more on instinct than emotion or thought.
Appearance -
Suppressed Form: Samaeal is actually rather tall, at around maybe 6'2" or so in stature. He is fit, being lean, trim, and in-shape. He has thick, neatly ruffled (in a cool way) black hair, narrow blue-purple eyes, a patrician nose, and a strong jawline, with a neat stubble on occasion, sometimes. He has a colorful butterfly tattoo on the nape of his neck. He also has smsll, sharp little black horns that sometimes blend in with his hair. Also has black nails, and a very long, lean, whiplike tail with a devilish, narrow spade-tip end.
True Form: Standing at a bit over 7', weighing in at a bit over 240 lb, he appears as the "Devil" in Salem, did (look it up), as an upright doglike form, with his usual horns becoming longer, with a slight twist, and his devilish tail becoming longer, and more whiplike. He is blackish turquoise with burgundy tinge.
Talents: In his suppressed form, he's a good cook, a great cleaner, and can play videogames very well. Knows how to lay a brawler-style beatdown in true form.
Flaws: Has a streak of not being able to save his masters, hates himself way too much for no reason, a bad liar, ironically.
Powers: In his suppressed form, he has superhuman strength, stamina, agility, speed, durability and a healing factor, he has some very slightly canine powers such as superhuman sense of smell and hearing. In his true form, his physical prowess is almost doubled, his senses skyrocket, and he gains the ability to generate and extend new limbs, enhanced natural weapons and armor, and certain organs, which he can retract at will.
Other: Often weilds a katana with a long blade that has a dragon etched on it. Often wears a cool denim shirt.
