he is a slave and has the number nine in white painted permanently on his back like dis-

he is made to work in some kinda place called U.B in u.b they use there slaves by making war weapons and such and never really gets breaks and is always pushed to work harder everyday.

no one else know about what U.B dose o the bots that work there.they get abused and tormented some even die from being caught in the machines they make.nine has seen it all and is always careful so he doesn't get hurt or killed.

the thing is him or other bots get enough Energon so they are very tried and weak from work and are always hungry.

his servos are made to also transform into tools and such so he doesn't always have to grab a tool or find it,

nine dose his hardest to work and make machines,but he wants to leave this prison and see the world of Cybertron and maybe other planets but no he has to stay here.

also, nine never knew he had a brother rung,they were close when they were sparklings but taken away from each other, one having the life of freedom and the light but the other living as a slave in chains and in darkness.
