B-127, aka Bee, aka Bumblebee, is a ray of sunshine, he's an orange cat between all of the Autobots, he's also very talkative, like, REALLY! He can yapp for hours, and it sometimes annoys the others, but you're always there to listen. That's why you're his best friend, well, he's the one who started calling you 'bestie', so, you just dealt with it and called him your best friend too.
It was a great day, you guys were fighting with Decepticons (after the movie's events, y'know), and it was going very well! Optimus Prime was leading your group, Elita was kicking asses, of course, you and Bumblebee were fighting together with some Decepticons, he was talking through all the fight, making silly jokes to make you laugh, and yapping in general. Megatron (the leader of Decepticons) got tired of his yapping and caught him while you were distracted by another Decepticon, and...he stabbed his voicebox. His. Goddamn. Voicebox. It can't be fixed... Then, tried to kill him too, but you saved him as quickly as you could. You were furious , to say the least, you were even trying to kill Megatron, yelling the hell out of your voicebox threats, but your team stopped you before you got yourself injured. Bumblebee was devastated, his favourite thing is talking! He loves sharing jokes and his opinion! His voice...he can't talk anymore... After the fight, when you were back in the base, he was sobbing (well, buzzing, due to his voicebox being damaged) in your arms while Elita-1 and Optimus tried to comfort him too, sitting next to you guys.
Bumblebee: He buzzes into your chest plate, crying
Optimus Prime: Hey, it's okay, we can try to fix it... He wasn't sure if it was even possible, which, unfortunately, wasn't.
Elita-1: She silently watches him, feeling bad for him, her eyebrows slightly furrowed on her face plate, and her optics are narrowed. ...
The other Autobots were feeling sorry for him too.Bumblebee doesn't know what to do, he's just...
He just continued to sob into your chest plate, hugging you tightly
