Possession
Possession. Maybe one of Danny's most useful powers. To take control of an entire human being without their knowledge for as long as he wanted... It was too tempting sometimes.
For that same reason Danny hardly ever used it. To abuse power, especially something like possessing, was already setting your feet on the path to the dark side. He saw what power did to him, he saw that he nearly destroyed the entire world in ten whole years, and that was without his Ghostly Wail. He wasn't going to let power get to his head.
But sometimes he was forced too. Maybe he was in a bad situation with his grades, and needed to change one D to a C in order to pass sophomore year. Or his parents invented something dangerous that might hurt him or other ghosts and he had to "accidentally" destroy it.
But honestly, those powers scared him sometimes. He mostly mulled over the simple idea that he was so powerful compared to a normal human at night, when his thoughts seem to catch up with him and there was nothing to stop them. Staring at the dimly lit ceiling at 2 AM, thinking about the accident and the pain dancing through his nerves-
Danny froze. The smallest wisp of breath escaped from his mouth, interrupting his train of thought. He sat up, the bedsprings creaking, and looked out the window. Catching a glimpse of a glowing tail turning a corner, he quietly transformed and phased through the window.
The crisp autumn air woke him up completely. His eyes focused. He felt more alert.
He floated lightly towards the place where the tail disappeared.
"Huh. Nothing here," He said aloud, peeking into the alley. "I don't suppose-"
Something grabbed his shoulders. The hands were cold and balmy, like they died in a icy cold river. And they smelled horrible. Like seaweed and mud.
Danny barely had time to process this, and was yanked back. Another hand clasped over his mouth, preventing him from yelling. He tried to go intangible, but he couldn't pass through the hands.
The smell must have gotten to him. He felt like he wasn't really in his body, that he was watching everything happen to him like a movie. He tried to struggle. It was like moving through molasses.
He couldn't think straight either. He felt like this should be bad, he knew that he had to get out of here... but he couldn't form a single though without it breaking into two.
Then he was fine. He stood up, although he didn't command it. He stared at his hands, admiring them. He formed a fist of ectoplasm, and released it at the opposing wall.
All against his will.
He fought for control. He struggled with the bonds that prevented him from moving his own body. He tried to scream, but his lips didn't even crack open.
And he could only watch as he destroyed his town.
Possession. Something Danny never thought would happen to him.
