The Mermaid Trio

Electric Ray Physiology: As a Japanese Sleeper Ray Mermaid (which is a species of electric ray), Kaminari is able to produce electricity naturally with her body. She can use these electric shocks to either temporaly stun her foe or to subdue her prey (usually smaller fish). While she is normally able to control her electricity, she tends to unintentionally release an electric shock if she gets startled.

Kaminari is normally a slower swimmer, but can do short faster outbursts and is very manouverable. Due to her arms are connected to her wing-like ray fins, she swims through the water as if she was flying, while steering herself with her tail. Luckily, her ray fins are flexible enough to allow Kaminari to move her hands like normal.

Human form: Like many other mermaids, Kaminari can take on a human form while on land. However, she gets transformed back into her true form if she gets submerged in water. Kaminari retains her ability to produce electricity even in her human form.

Musical and singing skills: As a musician, Kaminari is very skilled in playing on her shamisen. Her music is good enough to attract the attenntion of many people whenever she is performing somewhere.

She is also a good singer, usually coming up with her own lyrics for her music.

Staffmanship: As a former shrine maiden, Kaminari possesses a staff (which is a mix between a kakkhara and a purification rod), which she also can fly on, more like a witches broom (when flying she fits on it sideways). It can be also used as a melee weapon and amplifying certain spells. When it is not used, it takes on the form of a golden ring, which Kaminari wears on her right hand.

Ofuda: Her main ability as a shrine maiden is being able to create Ofuda (paper talismans) for various effects such as offense, defense and healing. Her Ofuda Spells:

- Talisman Bomber: Kaminari creates several paper talismans which throws at her foe. These talismans explode on contact.
- Talisman Blade: Kaminari throws several paper talismans at her opponent akin shurikens. These ones are sharp enough to cut stone.
- Sleep Spell: Kaminari uses a single paper talisman to throw at the foe, which sticks onto their forehead and putting them asleep.
- Healing Spell: Kaminari puts a single paper talisman at the forehead of the person, then uses her staff to channel Spiritual Energy, healing them.
- Divine Spell - Kagutsuchi Flame: Kaminari throws three paper talismans, which gets engulfed with fire and merge into a single projectile of fire.
- Divine Spell - Raijin Shock: Kaminari throws three paper talismans which turn into a powerful electric blast.
- Divine Spell - Barrier of Purity: Kaminari throws four paper talismans onto the ground to form a square. She then taps her staff to the ground to create a powerful pyramid-shaped barrier to defend against enemy attacks.
- Divine Spell - Fujin Breath: Kaminari creates one paper talisman between her index and middle finger then points it forward, releasing a blast of powerful whirlwind.
- Talisman of Light: Kaminari uses a paper talisman which can emit a bright light. It can be used to several purposes, such as blinding an enemy temporaly or creating a beacon of light (by placing it to the end of her staff).
- Talisman Double: Kaminari creates a paper talisman which can transform into an illusionary clone of herself. It can be used as a diversion.

Spiritual Energy: She possesses spiritual energy to use her shrine maiden skills, which can be depleted with Kaminari using her abilities too much, but she can restore it by eating and sleeping.

Placoderm Physiology: As a Botheriolepis Mermaid, Petra has bony plates (called osteoderms) to cover her upper body. These osteoderms provide her good protection against marine predators, such as sharks, greatly increasing the durability of her body. The plates on her arms can be also used as shields in case of an attack.

Her strength is slightly larger compared to a normal mermaid, but still inferior to that of a Merrow. Petra is strong enough to send medium-sized sharks packing.

Due to her armored body, Petra is on the slower side when it comes to swimming.

Hand-to-hand Combat: Due to her brave and adventurous nature often gets her into trouble, Petra has trained herself in hand-to-hand combat. Combined with her natural strenght, she can be a formidable opponent during a fight. During fights, she not only just throws powerful punches, but would also strike hard with her tail.

Survival Skills: Seeing her hotheaded personality, one could not tell that Petra is skilled in survival out of the wild. Actually it is her adventure-loving nature which allows her to think outside of the box and get herself out of a tight situation... or just punch her out of it.

Human form: Just like many other merfolk, Petra is able to take on a human form while on land. However, she gets transformed back instantly if she is submerged into water.

Hydrokinesis: Amethyst has potent hydrokinetic abilities , which allows her to control a certain amount of water in her vicinity. Others often describe it as if she is using water as an extension of her own body. While her hydrokinetic abilities are potent enough to whip up whirlpool capable to capsize smaller ships, she does have a limit how much she can control at once.

Water Magic: During her time of being captured by a Cecaelia and later on her land journeys, she gained an affinity for witchcraft and water magic. With the latter, she is able to conjure water magically as opposed to just taking control of existing water (as with her Hydrokinesis).

Her water spells:
- Arcane Torrent: Amethyst puts her hands together and fires a powerful stream of water.

- Abyssal Slicer: By waving one hand, Amethyst releases several blades of water.

- Glaucus Bomber: Amethyst fires several bombs of water from her hands.

- Hydro Javelin: Amethyst lifts up one hand and creates several spears of water, which she launches at the foe.

- Aqua Aegis: Amethyst puts her hands together and creates a dome of water around herself and her allies for protection.

- Ocean Waltz: An underwater Hydrokinesis technique. Amethyst swims circles around the foe, stirring up a whirlpool in order to trap them.

- Jet Hammer: Amethyst surrond her right fist with water and strikes the foe with great power.

- Hydro Lash: Amethyst uses a whip of water to strike or bind the opponent.

Potion making: Amethyst is shown to have some skill in potion making, since she made one which is able to turn humans permanently into merfolk.

Merrow Physiology: As a Merrow, Amethyst is particarly strong. She is much stronger than a human and is able to lift up heavy object with ease, as well as to wrestle powerful aquatic predators (such as sharks) and grown human men into submission.

Her mouth is also full of sharp teeth (with her canines being fang-like) and has a powerful jaw. I myself could compare this to that of an otter.

Being a Merrow, she is also a fast and skilled swimmer.

Human form: Just like many other merfolk, Amethyst is able to take on a human form while on land. However, she gets transformed back instantly if she is submerged into water.
