I did this some weeks (months? O_o) ago... I split in two some people's characters that requested it (just like I did with my witches time ago: [link] [link] [link] [link]).

-- First one was :iconmistylear:'s character, Aleph.
She divided into two new people: Beth and Tav (second and last letters in the Hebrew alphabet, since Alpeh is the first one :P).
- Beth got all of Aleph's shyness. She barely can talk or simply be too close to anyone. It's a serious problem. She's not a warrior, and the only magic she retains are healing powers. But it's hard for her just took enough courage to heal someone.
- Tav is curious, inquisitive and always wondering about people and how the world works. But she completely lacks manners. Not very ladylike or elegant, Beth got that part. In battle, she uses her offensive magic power without consideration, can be really scary at that point.

-- Second one was :iconzeroforever:'s Tammy, formerly Tim, from the Overlord Bob universe.
The two halves in which Tammy has been divided are:
- Thomasina: Even more sweet, tender, bubbly and bimbo-esque than Barbie. She's happy and in love with Barbie, and there's no much more to tell about her, because she's... well, you know, simple-minded.
- Tamylin: Basically, she has recovered Tim's original personality, but without any of his masculine traits. Theoretically, that would make her an enemy of Barbie again. However, she's still in love with Barbie, so she's gonna have a pretty high number in her "tsundere" stat. :P

-- And third, cyero's character Oublitette, who already has a double personality! (Sorta...)
Oubliette was separated in the following two parts:
- Miette: Well, that was unexpected! Even when Oubliette just *pretended* to be a silly teenager sometimes, this part of her mind has come to life in Miette's form. But Miette is much more innocent than her fake counterpart.
Being this her origin, she fells like a fraud, even if this time she's not posing!
It's very confusing for her, but she's a real part of Oubliette's mind... She's the part that makes Oubliette to hold herself back!
- Oblivion: With the good part of Oubliette's psique gone, Oblivion's got all the craziness and all the murderous thoughts. She can't barely react rationally, is near to behave like a beast.
Not a good idea to stay close to her. :P
