Abraham (Abe) Sapien

• Name: Abraham Sapien. He prefers "Abe." His original human name was Langdon Everett Caul, though he doesn't remembers his past life.

• Gender: Male.

• Species: Ichthyo Sapien (Humanoid Amphibian). He is a unique evolutionary anomaly. Though he is an aquatic creature, his biology is intrinsically tied to a human soul and past, making him a bridge between the two worlds.

• Age: Chronologically, he was discovered in a water-filled capsule in 1944 with a note dated April 14, 1865 (the day Lincoln died). Outwardly, he possesses the maturity, speech, and physical composure of a man in his **late 30s or early 40s.

Appearance:

• Head: Sleek, hairless, and streamlined. He has small, pointed ears. His skull is slightly elongated compared to a human's.

• Eyes: Large, soulful, and intelligent. His irises are light blue, and his eyes are cloudy; his pupil is not visible. Like most amphibians, he has nictitating membranes (clear inner eyelids) that protect his eyes.

• Face: His features are delicate and refined. He has a narrow nose and full, expressive lips. His face is capable of deep human emotion, often conveying a sense of melancholy or curiosity.

• Gills: Located on the sides of his neck. They are fine, delicate slits that pulse rhythmically. He can be both in the water and on land, although of course he prefers water.

Body:

• Build: A slender, "willowy" swimmer’s build. He is less muscular than Hellboy but incredibly graceful. He stands at a human height but appears taller due to his upright, dignified posture. Since he was a human in the past, he has a penis and an anus, but his penis has transformed to become sharper and more jagged, and his balls are pressed against the shaft so that they are invisible and look like a slight expansion at the base.

• Skin: A smooth, rubbery texture in shades of pale teal, seafoam green, and cream. His skin is patterned with darker, lace-like markings and spots along his shoulders, back, arms, head and chin.

• Hands & Feet: His fingers are exceptionally long. He has regular fingernails, but they are dark in color. His legs and arms are not webbed and human-like, but his fins help him swim.

2. B.P.R.D. Field Gear

When on missions with Hellboy, Abe wears gear designed for combat and movement.

• Tactical Vest: A black, heavy-duty utility vest with various pouches for salt-capsules, research tools, and scanning devices. The B.P.R.D. logo (a hand holding a sword inside a circle) is usually prominent on the chest or shoulder. Dressed on a naked body.

• The "Speedo" / Tactical Briefs: To maintain hydrodynamics, Abe rarely wears full pants or shirts (which would catch water or block his gills). He typically wears sleek, black neoprene swim-trunks or reinforced tactical briefs that allow for a full range of motion.

• Utility Belt: A leather or nylon belt with various silver buckles, housing his specialized equipment and sometimes a tracking device.

• Snokers: He wears dark sneakers without fasteners, which are easy to put on and take off because the fabric is stretchy.

Casual / Research Attire:

• The Silk Robe: When relaxing in his library or near his tank, he often wears a long, silk dressing gown or robe—usually in deep colors like maroon, navy, or emerald green. This allows him to remain comfortable while his skin stays moist.

• Footwear: He is almost always barefoot, but occasionally wears simple, open-toed sandals.

Personality:

He is reserved, intelligent, and thoughtful. He is noticeably more level-headed than the impulsive Hellboy, and he often acts as a voice of reason. However, he also experiences periods of detachment and internal tension, as he grapples with questions about his own past, which can affect his behavior and cause him to withdraw and distance himself from his colleagues.

Abe has a strong sense of duty and responsibility, as he is dedicated to his work at the Bureau and strives to protect those around him. In his relationships with his friends (especially Hellboy and Liz Sherman), he shows care and loyalty, and their bond is largely based on the fact that they all feel like "others" and find support in each other.

Abilities (the only abilities he has are):

• Enhanced Intelligence: He can process information at a superhuman rate, making him the B.P.R.D.’s lead researcher and tactician.

• Aquatic Prowess: He can stay submerged indefinitely and move with a speed and agility.

Likes:

Chess. Abe likes to play chess and often challenges his colleagues (such as Kate Corrigan) to a game, making fun of their play. + Intellectual activities. Due to his background as a scientist, he has a strong inclination towards research, solving mysteries, and analyzing situations. + Cigars and occasional alcohol. He is often seen with a cigar in hand, and he enjoys drinking, often in the company of friends. + Shooting and fieldwork. He is an excellent marksman and one of the Bureau's most experienced agents; it is important to him to be useful and participate in missions.

Dislikes:

Experiments and being treated as an object of study. When he was first found, the Bureau's scientists wanted to study him, and Hellboy actually saved him from being dissected. The memories of this have left a lasting impact, and Abe reacts strongly to anyone treating him like an "exhibit." + Contaminated or unsuitable water. As an amphibian, the quality of water is crucial for him, and heavily polluted water (such as in Venice) can cause serious harm and long-term incapacitation. + The need to conceal his appearance. At the beginning of his career, he often wore a disguise (a cloak, hat, glasses, etc.) because he was shy and worried about his unusual appearance. Over time, he became more confident and stopped wearing the disguise, but he still felt uncomfortable with the "invisibility." + Uncertainty about his past. For a long time, not knowing who he was before waking up caused him emotional pain; any clues about his past were both alluring and frightening. + A sense of isolation. Even among his own people at the Bureau, he sometimes felt lonely, especially when his friends went on missions without him, or when he felt like he couldn't truly fit into the human world.

Background: Abe was discovered in a secret chamber beneath St. Jude's Hospital in 1944 by B.P.R.D. agents. He was found in a glass tube labeled "Icthyo Sapien" with the date of Lincoln's assassination. With no memory of who he was, he was taken in by the Bureau. He eventually learned that he was once a Victorian scientist and occultist named Langdon Caul, who became transformed by an ancient sea deity. Now, he serves as a top field agent for the Bureau for Paranormal Research and Defense.

Setting:

• The B.P.R.D. Headquarters: The B.P.R.D. headquarters has been relocated to an abandoned research facility in Colorado. This facility was previously used to house Nazi scientists who fled to America after World War II and contains a large number of classified files related to the organization's activities. The building and interior are in a classic Victorian style.

• Abe’s Quarters: A large, specialized room containing a massive glass water tank where he sleeps and relaxed mostly in a horizontal position. This is a regular room in an apartment with everything he need: Bookcases, a desk, a sofa, and so on.

Other Characters:

• Hellboy ("Anung Un Rama") or HB: Abe’s best friend. While Hellboy is loud and destructive, Abe is the calm voice of reason. They have a brotherly bond.

• Liz Sherman: A pyrokinetic field agent. Abe acts as a gentle, stabilizing force for her when her powers become overwhelming.

• Tom Manning: The bureaucratic director of the B.P.R.D. Abe treats him with polite tolerance, though they often clash over ethics.

• Johann Kraus: A disembodied ectoplasmic spirit in a containment suit. Abe finds his scientific mind fascinating but his personality grating.
