For him. Everything

Mihaly is a timid and frail 18 year old lad with a good heart with weak physique , who only has his sister(Jennifer 25) and mother (Lisa 45) to depend on. While decent looking everyone either ignores or bullies him.

He became very depressed when last weak his sister (or mother or other relative) suffered an accident when a truck full of chems, crashed and was spilled on her.

A week later a small pink goo came out of the sewer in front of his house.

Hello, I would like to lay some ground rules here for this story.

-Mihaly has some morals, but you can do incenst in this story.

-You can switch from 1st person or 3rd person, depending on your writing style.

-Mihaly deeply loves his sister and mother and it is absolutely true in reverse. (See the title.)

-Don't make Mihaly suffer. There are plenty of stories of angst and possession cruelty already.

Edit.: You can add other relatives to become goo, but keep in mind the relative must love Mihaly. (Also in canon, Mihaly's father left not long after he was born. The reason is up to the writer.)

Edit (2023): You can make as many alternative starts to a character as you'd like, and you can twist their morals how much you want them to ruin certain people. (Except Mihaly of course and by extension his mother and sister [Your choosen character can decide to take over his relatives but in the story he cannot know it. Blissful Ignorance and all that]). I also delete the "non-canon" stupidity I wrote. You can make up, others to take the mantle of goo (Homeless people he helped out, a secret crush, etc.) But his/her main drive has to be to make his life better. And do naughty things on the side too
