My current main, The Tranarchist, is a vampire. She's loosely based on a Lasombra I (too briefly) played in Vampire: The Masquerade (V20/4th edition). Since the tabletop version had shadow controlling powers, I originally made her a Darkness Controller. But that wound up being no fun to solo, so I've rebooted her as a Necromancy/Darkness Mastermind, which has been super fun so far. (Who better than a Necromancer to raise this thread? 😅) She started as a Hero but she'll probably go Vigilante pretty quickly.
Since she's trans, she didn't start HRT until after her first puberty, and she didn't have much in the way of surgery before she became undead, I played around with the face and body sliders to try to make her more visibly trans. I started with the "Strong" face shape and then tweaked from there, made her whole head slightly larger in proportion to her body than usual, maxed out her shoulders while minimizing her hips, and cranked her physique up to the max. (I admit I also maxxed out the bust slider and that was purely self-indulgent on my part. I can have a little wish fulfillment as a treat.) I plan to periodically and indefinitely keep changing her hair color and I don't intend for it to ever be natural.
She originally had a trenchcoat but I decided to give her wings, so I chose the Bone Wings, because she's a Necromancer so it made sense to me that she could graft those on. The wings are only on her second costume, which is identical to her first in every other respect, so when I hit the macros I created she does an emote and switches from one to the other, so she only has wings when she's actually Hovering. She gets around on the ground in Panther Form (feels thematic) and in the air with Hover + Teleport (taking shortcuts through the same extradimensional Netherworld that Darkness powers tap into).
I used the Slime aura to make it look like she's cutting herself open and draining her own blood to fuel her powers and animate her zombies, except for Twilight Grasp and Life Drain, which she uses to drain her victim's blood from across the room like the titular protagonist of Blood Omen: Legacy of Kain.
