how do you put a slender like enemy in unity?

i want to make a slender like game but i dont know how to put slender in it!

One way I figured it out was to make a cube, then put a picture of “slender man against a white background” on it…but I dont know how to shape the cube to fit his body shape…hope this helped.

Okay you could use another method I used. Make a cube, scale it to a torso size for the Slender Man then make a sphere for the head and make a cylinder and duplicate it for arms and legs
