i'll put a new pretty image here eventually. hold this spot.

Siobhan Chark (she/they) is a tall dark-skinned Black woman, standing at 6'6", with impeccable posture; as a professional athlete, she has a well-toned physique. She has long teal hair typically kept in box braids and in an updo or semi-updo, though other styles aren't unusual.

As an Atlantean, Siobhan has an array of aquatic traits and adaptations; they have black sclera and uncannily pale blue irises, and their ears finish in grey fins. Their teeth are quite sharp, though unlike a real shark they don't have more waiting in reserve.

In the dark, Siobhan's fins and skin light up with bioluminescence in a faintly freckle-like pattern.

Covering her left shoulder, part of her left upper arm, and reaching to her neck and left cheek, Siobhan has a lichtenberg scar. It's long-healed, but normally it glows with a faint neon pink light; this glow becomes a violent light when in the presence of reality stuttering or certain kinds of arcane radiation. This is a god-scar, left by being caught in reality flickers too many times over too short a period, and may register as magically or supernaturally unusual / containing the residue of a divine entity to anyone who can sense that.

She keeps a sharkskin tied around her waist when not in her home city of Atlantis, and can use this to change between her "human" form and a "mer" form, where her lower body is replaced with one resembling a shark's. In mer form, Siobhan can swim through sand and the air just as easily as water, and their gills make them fully capable of indefinite underwater survival.

Siobhan has a very faint Irish accent. They suspect they're at least a thousand years old and may have originally been human, though long exposure to the shifting realities of Atlantis has made their memories... 'multiple-choice', for lack of a better word. Did they do that, or did some other Siobhan in a timeline and world very much like this?

As a Blaseball player, when in universes where the game exists and she is actively on a roster, Siobhan cannot be killed by anything except what the game has ruled can kill Players. This may be why she doesn't age (players don't age), but she thinks she probably would be immortal regardless. It's hard to say.

She's not actually a shark selkie, she doesn't have a full shark form (only mer and 'human'), but that's the rules of reality her current existence mostly plays by. She's not a shark, she's a "shark", but she's not going to correct you. Yes, she can hear the quotation marks. No, it's not really that important.
