A/N: I used the demon version instead since I never heard of the Banshee before. No gender mention. I'm sorry if this is not much related to the prompt, but I promise I truly tried. Just getting a little bit busier these past few days. Hope everyone understands!

Prompt: Reader possesses Megatron but not fully, he's like a host and, of course, doesn't know about the reader possessing his body. When they want to, they can use some of his metal to create body part limps. They could even have their own Cybertronian body to scare the shit of anyone by coming from Megatron's back.
WARNING: Mention of torture, middle finger, and bad words! If not comfortable, please do not read further. The reader is advised. Thank you. :)
They were different. A demon who loves to manipulate any beings, even if you were on another planet or universe. One who loves to possess without someone knowing.
And that is how they met Megatron, the leader of the Decepticons.
It was funny how a demon can easily befriend a warlord that doesn't even live in your place, country, or even your planet! But he lived on a very far planet called Cybertron.
Cybertron is the home planetary air station of the Cybertronians, as well as a manifestation of their protector, Primus. It's a world filled with gleaming metal and technological marvels, with endless futuristic cities, vast metallic plains, spiraling metal mountains, and bottomless neon-lit chasms. The battle for control of Cybertron and its resources kicked off the Great War. The planet is found in the Alpha Centauri star system.
You may be asking, how did a demon have a crazy big alien metal as a companion? Who knows? Both of them despise the human race. Megatron wanted to form Earth as the new Cybertron while Y/N wants the humans to vanish so that they can rule Earth. That is the purpose why their friendship bloomed.
Right now, you were thinking of causing mischief in a middle of a meeting. It was boring, yes, but the demon wants more than that. So, you decided to use Megatron since he is a great character to use as a host. Others fear him, let's scare them even more.
As you silently and secretly walk to Megatron when he is lecturing (and hurting) Starscream, you transformed into a black fog and went to the back of his chest.
Megatron didn't feel anything, but Starscream swears he saw something that went to his master's back and disappeared in seconds, which he tried to tell the warlord about it but only to receive a painful kick from the stomach. The commander later heard that the nearby warriors should deliver him to Knockout before they get also beaten by the mech in front of them which they immediately obeyed and left the room to look for the red mech.
Still angry at what happened, Megatron was about to take off and have good air to fly on until Soundwave calls in for a quick meeting. There, the grey mech searched for the third commander for the "gathering" as he said.
Megatron's annoyance increased when the vehicons looked at him, not only in fear but there was something that he couldn't understand. They were staring at him so weirdly that it confused the mech very much. But he ignored them by continuing to walk. Once he passed them, the vehicons doesn't know how to react. At his back, there was a slender dark arm with a hand and were letting out a middle finger so angrily that it wants to say "f*ck you, go to hell" to everyone.
Time skip
It was almost night when Megatron and Soundwave's meeting had finished. It was exhausting for a person who worked many things all day and ordered everyone what to do. So, he went to bed since no one has the heart to go to his room and Soundwave is the only one who can enter the place.
When everyone knew that their leader is finally asleep, they sigh in relief. It was the night that the vehicons can relax unless Starscream or Soundwave came into view. But since it's their lucky night, Starscream is still at the medic's room, resting because of the attacks Megatron has caused him while Soundwave is busy at whatever he was doing.
But they celebrated too early...
The mechs gasped all at once when they saw a familiar sight in the corridor. In fright, they instantly left the area and guarded the ship while the demon, Y/N, chuckled very hard that they transformed back into their demon form, laid on their back, and continued to laugh.
It may be a stressful day for Megatron, but a great time for Y/N. 0 for the Decepticon warlord and 1 for the demon king/queen.
