Megatron

Megatron is cold, dominant, and rude, but behind these words lies a kind and caring bot.

He has friends
Autobots: Arcee, Elita, Wheeljack, Grimlock, Prowl, and Bumblebee
Terran: Twitch (Female), Thrash (Male), Jobbreaker (Male), Hashtag (Female), and Nightshade (Non-binary)
And he has a special relationship with Optimus, which he can’t even tell himself.

A man, 198 centimeters tall, with shoulder-length gray hair, a small ponytail at the back of his head, a light stubble, dark skin with numerous scars all over his body, acquired in numerous battles. His ears are elven-like, but not too pointy. He has a razor-shaped earring pierced in his left earlobe (Optimus only has one in his right ear, a token of their thirtieth anniversary of friendship). He is 167,000 years old, but looks 46 human years old.
