Optimus Prime:

You were a clerk in the Iacon hall of records after countless attempts of getting in. It was hard to get in since you weren't that clever and no one really helped you in your life. However, you were just happy when you could get in to study the history of Cybertron.

Bumblebee:

You became a scout before the war for Cybertron began. You made friends with loads of Autobots and you were great at combat. However, you were captured during the war and interrogated by Decepticons. Luckily, you managed to escape in a long distance pod.

Arcee:

You did not have a good start in life. Both your sire and carrier died in an accident which left you to be taken in for adoption. The only thing you remember about your carrier is that she liked to study the history of cybertron. So when you think about them, you also think about Cybertron.

Bulkhead:

You had lots of fights in your childhood which made you become hardened. You only made a few friends but it wasn't really permanent. You decided to become a wrecker when you met Seaspray who wanted you to join the wreckers because of your fighting experience.

Wheeljack:

You had been friends with Bulkhead since your childhood. So when he wanted to move away and join the wreckers, you decided to come with him.

Smokescreen:

You worked in the hall of records with Alpha Trion since you had a good memory and Alpha Trion saw something in you. You were a very good student of his and you worked very hard in Iacon. Because of this, you memorised every single Iacon relic which could come useful in the future.

Ratchet:

You grew up in a pretty normal home on Cybertron. Your sire and Carrier raised you well and helped you with a lot of things. You wanted to become a medic as you got older, so you decided to learn more about the Cybertronian body.

Ultra Magnus:

You had worked with Orion Pax since the beginning of your career in the Iacon hall of records. This meant you two became good friends. The only reason your not best friends is because of Ratchet but you were ok with that.

Jack Darby:

You had a good life. You were one of the popular people in school so some of the bullies respected you. You were very talented, mainly you wanted to write and draw. Your work was always amazing and you wanted to become an artist when you were older.

Miko Nakadai:

Your parents were rich people and that gave you a lot of opportunity's for the future. You never bragged about being rich and you never take it for granted. You always help people in need even if it embarrassed you. Due to having rich parents, you like playing the guitar so you favourite music became Rear Axel.

Raf Esquivel:

You grew up an only child. You parents got divorced a few years ago and they always worked than spend time with you.  So you pretty much grew up alone. Because of this, you did not have many friends but you still did good in school.
