Alright, here's the character profile for my 3-D being who used 4-D powers to defeat an Infinite-D, I came up with him last night, so I already have some stuff ready:
Good or evil: Evil, he's the villain.
Gender: None.
Indentifies as: Male.
Race: Living plot hole.
Originates from: Nowhere. He is the living embodiment of a mistake made by God, he is simply a piece of reality that makes no sense, he is a "plot hole".
Physical appearence: Human. White skin and black hair, easy to miss in a crowd if you don't pay attention.
Goal: To defeat "god" and take total control over the "plot", so he could rewrite the world so he could actually fit inside of it. The world he plans on creating is entirelly "wrong" and would not last much, resulting in the total destruction of reality.
Relationships:" Hates "god" for never helping him or fising the "plot hole". Starts by seeing the main characters as annoying people who get in the way of his journey, but later grows to respect them. Loves the ghost of his daugther, and wants to keep her away from the fight.
Friends: The ghost of his daughter. Both his daugther and wife died in an accident, because "god" affected the plot. "Plot holes" are easy to destroy when they are children, but it gets harder when they grow up, that's why "god" can't kill him in the same way, but "god" does try to kill him like that frequently, which ended up basically destroying his life.
Sexuality: Bixesual.
Skills: Good leader and strategist.
Weaknesses:" Not very good at fighting directly, and can get nervous if his plans go wrong.
Occupation: Unemployed
Hobbies: Likes to read bad fanfiction in his spare time.
Introvert or extrovert: Introvert, he is easily forgetable, and doesn't like to talk to people. He is also very analitical, but can get angry in certain situations.
Fears: Fears being defeated and having to suffer the wrath of "god". Fears that his daugther's ghost is not actually a ghost, but actually a hallucination, and that he is actually just a mad man. Fears that even if he sucesseds, he will still not fit into his new world.
Religious or atheist: Religious, knows for a fact that "god" exists.
Would be willing to give up his life so that: So that he could escape "god" and have peace. So that his daugther could come back and have a normal life.
Basically, this guy was created by mistake, he shouldn't exist, and so "god" is trying to undo him via Plot Manipulation, which ends up destroying his life, but he survives. He retaliates by making up a plan to kill "god", and the main characters have to stop him, because his actions may end up destroying the entire world.
I didn't write any story featuring him yet, and I'm not sure if I ever will, I just had this idea last night.
