A dead 19th century philosopher that returns as a ghost, his name is Friedrich Wilhelm Nietzsche. He has a full body, but it's see-through, his see-through body is Cyan colored. He has a mustache and glasses in his suit pocket so he can see even though he has no eyes due to being a ghost. He can go through things and hover/float in the air since he's a ghost. The only thing that doesn't go through him is a fellow human being, so he can touch people without going through them.
