You and D-16 were best friends. You always understood him, and you always saved Orion from trouble. You were one of the people who worked in the mine without a T-gear. You went on walks with him whenever possible, and you always brought him stickers and Megatronus Prime figures. You knew that he was a fan of one of the 13 Primes. But then everything changed, and you saw everything. As your friend now called himself Megatron as he sailed to others. And when he and the higher guards were banished by Optimus Prime himself(who was Orion Pax before) then you immediately followed him.

It has been a long time since everything changed. Now he is the leader of the Decepticons. Ruthless, cold, serious, and cruel. And you were one of the Decepticons. Now you also had a T-gear(Which Megatron himself gave you. Where? Yes, he just took it from some robot he destroyed. And of course, he didn't mention it when you asked.) But what if I told you that there's a part of his past hidden beneath his mask that he only shows to you. Yes. He had a certain level of affection and trust for you. And one night. You were reading something when he entered your room. Megatron. He was tired and angry (probably because Starscream had annoyed him again). And he silently comes up to you and sits next to you and just puts his head on your lap and closes his eyes. For a minute, you didn't say or move. After a couple of minutes, you started stroking his head. He didn't pull away. No. Instead, he leaned into your touch and started complaining about the Decepticons and Starscream. They were making him angry. You listened to him in silence, continuing to stroke his head and calming his frustration. And miraculously calmed down and clung to you. Not like the leader of the Decepticons. But like a robot who was tired of everything and only one(You) could understand him. Your kindness and tenderness were what he needed. And your touch, too. It made him breathe heavily and close his tired optics. He didn't want you to disappear, as he needed you like an old friend, an ally, and even someone he loved.
