Shinzu
Species- Human
Height- 5'11"
Age- 39
Eyes- Usually dark brown; Red if using Fire Aspect, Blue if using Water Aspect, Grey if using Air Aspect, and Green if using Earth Aspect.
Hair- Long, and dark brown; tied back in a low and loose ponytail.
Build- Athletic and quite muscular.
Clothing- Grey, cotton vest, and loose cotton pants.
Abilities- Skilled mixed martial artist (with a favor for kung-fu), extremely strong and fast. Has Elemental Aspect abilities. Fire Aspect increases his strength and the ferocity of his attacks tremendously, but decreases his awareness. Water aspect increases his awareness, mobility, and grace when fighting, enabling more accuracy and the ability to sense attacks before they reach him. Air Aspect increases his speed and heightens his jumping. Earth Aspect makes it harder to hurt him, and much harder do knock him down.
Personality- Shinzu is kind, patient, and selfless. He's someone who always wants to do the right thing and help everyone he can.

Jennifer Suki, M.D.
Species: Demon
Eyes: Yellow with slitted pupils. In public, wears colored contacts.
Height: 6'1"
Hair: Shoulder length, pink.
Build: Athletic
Occupation: Diagnostician (Head of Diagnostics Department)
Personality/background: She's cynical, sarcastic, and can be a bit abrasive. She's rough around the edges, but she's got a soft center.
Suki has been around for a while. A long while. She struggles with making friends because she hates living past there life spans (watching them die) and decides avoiding the problem is the best answer.
She did try dating someone before, but once they found out she was a demon, they left.
Still hurt by this, she doesn't open up to people easily. Once she does, however, she is very loyal, and can be a big softy.
As a side note, she's very musically inclined, and can play cello, piano. and guitar!

For those who don't know about Undertale... (MAY CONTAIN SPOILERS)

-UNDERTALE is a role-playing game that uses a top-down perspective. In the game, the player controls a child and completes objectives in order to progress through the story. Players explore an underground world filled with towns and caves and are required to solve numerous puzzles on their journey. The underground world is the home of monsters, many of whom challenge the player in combat; players decide whether to kill, flee, or befriend them. Choices made by the player radically affect the plot and general progression of the game, with the player's morality acting as the cornerstone for the game's development.-

-CANNON THINGS that MAY be important to know when RPing in my verse-

STATS
(Don't worry, I'm not going to go DnD on you. These are just for fun)

HP- Hit Points, or Health Points
ATT- This is ATTACK. Essentially, this is how much DAMAGE a someone can give when fighting.
DEF- This is DEFENSE. This is how much damage someone can take without lowering their HP.

LOVE (Lv)- An acronym. Level Of Violence. This is a stat for humans (canonically) that measures how many monsters they have killed. The more LOVE a human has, the stronger they become.
Exp- Another acronym. Execution Points. This how a human increases their LOVE; by killing monsters.

BLUE and ORANGE Attacks

Blue- If you stay still while being hit by a blue attack, nothing happens, and you don't take damage. If you move, that's a different story...
Orange- Orange, is the opposite of blue. If you can't dodge, move through it, and you will be a-okay.

REGARDING MY AU

LOVE- It doesn't just apply to Humans; it applies to Monsters as well! It's the same mechanism, it just works for both races.

MAGIC LEVEL- This is used to measure the strength/complexity of someone's magical abilities, on a scale from 0-10, 0 being almost no magic, and 11/10 being someone who exceeds ASRIEL DREEMURR in magical ability.
(Magic Level doesn't necessarily measure power.)

SOUL TRAITS
Instead of seven HUMAN SOULS (referred to as soul traits), my AU has 17.
The seven original traits each have an opposite, with the exception of Determination:

DETERMINATION (Red)

BRAVERY (Orange) | COWARDICE (Navy)

JUSTICE (Yellow) | CORRUPTION (Dark Purple)

KINDNESS (Green) | CRUELTY (Maroon)

PATIENCE (Cyan) | AGITATION (Rust Orange)

INTEGRITY (Royal Blue) | DECEIT (Darkest Orange)

PERSEVERANCE (Bright Purple) | CAPITULATION (Dark Yellow)

BITTERNESS (Light Grey)

SPITE (Dark Grey)

VENGEANCE (Firey Orange, glows Yellow)

HATE (Black)

Both Humans and Monsters can have Bitterness, Spite, and Vengeance, but only humans can have HATE.
Bitterness may lead to spite, and spite to vengeance in Monsters, and spite leads to Hate in Humans.
