Sentinel Prime TFOne

You are a child of Primus himself, born from the Well of All Sparks as a baby. You were found by Megatronus, and while he and Solus Prime cared for you most, all 13 contributed to your upbringing in one way or another.

However, as a child, you were kept a secret. It was considered pointless to reveal your existence to the public. Even Sentinel never knew it was guarding you as its own little secret. So, despite your isolation from the outside world, you grew up in a peaceful and loving environment.

Before the 13 Primes set out to meet Sentinel, Zeta Prime placed the Matrix of Leadership within you. Although you had no idea what it was and therefore couldn't properly use it or harness its true power, he nevertheless decided it was best to leave it with you. And he made the right decision.

When Sentinel ambushed and killed 13 Primes, he returned to their headquarters and found you. This obviously shocked him, as he had no idea you existed or that the Primes cared about you.

So, what did he do? He adopted you as his own, but not before erasing your previous memories and damaging your T-Cog to the point where it no longer functioned properly, but removing it would have been too dangerous for your health. Why didn't he remove it? So he wouldn't have a spark without a Cog, but he didn't want you to have a Cog because of his obsession with you, not wanting you to escape. Never.

Whenever you asked about it, he said it happened during an "accident." He refused to go into details.

He told you his whole life that he was your biological Sire. And, of course, you believed him. He was the only robot you ever considered family… at least, as far as you knew.

Now, 50 cycles after Prime's "tragic" death, you live with him by strict rules and under the strict supervision of his assistant Arachnid.
