Author's Note: Haven't done a story on here in ages! So this is actually a cross-post from Archive Of Our Own (AO3) and finally decided to upload it onto this site.

This story will be based off of Transformers: Animated, however it will be AU and will not completely follow the storyline, mainly because I don't know the entire storyline but know most of the characters in the series.

Also here is a bio of my OC and who the story is going to be based off of :)

Name: Ome (Pronounced O-mey).

Age: Early 30s in human years.

Height: 5ft 5 inches tall.

Faction: Autobot.

Rank: Warrior.

Sexuality: Straight.

Birthplace: Cybertron.

Creator(s): Omega Supreme (Sire).

Accent: British.

Personality: She is seen as quiet and shy around those she doesn't know, even weary at times, but once she gets to know them she is friendly and can even be cheeky at times, but she can be fierce against the enemy, so she is not one to be underestimated.

Appearance: She has a strong and slender build and her armour is coloured electric blue with black accents, her optic colour is crystal blue but she has a scar on the right side of her face, so her righ optic is slightly lighter and is blind in it. She has audio fins and she has tendrils on her helm, they are swept back and reach down to just above her aft, they are coloured black and the ends coloured electric blue. They are also functional and can be used to grab things, plug into devices, and hack into devices if necessary, but they can also be used as an offensive attack by shocking the enemy. On her forearms are two powerful blasters, and she has a battle mask that covers her nose and mouth when in battle, but it can be retracted when not in battle.

Background: She was the last Sparkling born from Vector Sigma, unusually she had no Creators, so the initial decision was for her to be sent to the Youth Sectors. However the Autobot Guardian, Omega Supreme, did not want her to be without a family, so he decided right then and there to take her on as his own. He formed a family bond with her and raised her to the femme she is today, the two share a close Sire/Daughter relationship and she would always be seen with him, she would even team up with him as a last line of defence, other times she would be called in beforehand or to battles her Sire wasn't needed in. After the last battle on Cybertron, and after Omega had to be put into a modified stasis from severe injuries, she went with the Autobots to Earth to search for the AllSpark.

Human Appearance: She looks to be in her early 30s with a strong and slender build, her eye colour is the same crystal blue as her optics, but she has the same scar on the right side of her face, so the skin on that side is slightly lighter and rougher texture. Her hair is long and reaches to just above her aft and is coloured black, but the ends are dip-dyed electric blue. She usually wears a black t-shirt with a black and blue jacket on top, she also wears a pair of black combat jeans with a blue belt, along with blue and black trainers.

Likes: Music, Spending time with friends and family.

Fear(s): Loosing her Sire, pitch black darkness, creepy crawlies and lightning.

Now the other thing you need to know is about Omega Supreme, in the series Perceptor talks about how he has a 'simple processor',and Ratchet becomes his mentor bot. However in this story it will be different, if you have seen the Transformers G1 episode 'The Secret Of Omega Supreme', then you will know that he had a past with the Constructicons. I wanted TFA Omega to have the same past, the only difference is that there wouldn't have been a Robosmasher so Omega wouldn't have had his emotions effected, instead he would not be as quick to trust and no one would know of that part of his past, only Ome when she was an adult. So Omega would be a lot older, he wouldn't have a 'simple processor', and he would have more experience in the war, despite his younger-looking appearance, and he would have battle scars as well. He would have worked under the Elite Guard initially, until after the destruction of Crystal City (because of the Constructicons) where he would have had a new duty in being a last line of defence because of the war starting, Autobot Guardians are well respected and have leeway on who they want to follow orders from, and Omega had decided to join the Autobots as it worked out better for him. He would be the oldest Autobot Guardian and there would have been eleven others (search Omega Sentinels on Google), but now there are only two left, himself and Sigma Supreme who is the youngest and works for the Elite Guard, he would follow only Ultra Magnus' orders, while Omega would only follow Optimus' orders.

Omega would have met Ratchet after one of the battles near the early years of the war after he had sustained an injury (at this point he would be an Autobot rather than an Elite Guard), and it would have taken Omega a while to trust Ratchet as a friend, he already respected him as a Medic and would allow him to treat him. So in this story, Omega and Ratchet would be old friends rather than mentor and student.

Another thing is the weapons Omega has, in the cartoon he can't retract his weapons, but in this story he can retract his weapons which would reveal his hands, it would make things easier for him when it comes to raising Ome.

There is one more thing to be aware of, Omega would have PTSD (Post-Traumatic Stress Disorder) because of the betrayal and the battles he has seen, it would make sense. If this makes you uncomfortable, I apologise and would recommend you to not read this story if you feel it will be triggering for you, the last thing I want is to make anyone feel uncomfortable, so please read at your own discretion. But despite what he has, Omega loves his daughter and does do a great job taking care of her.

Also here are the personalities of each of the Autobot Guardians, just as a disclaimer it isn't head-canon to the TFA series, this is my own take on their personalities. So in age order, their personalities are:

Omega Supreme - The quiet one, hard time trusting, a bit serious, cares about his family, has a wit to him, someone one would not want to anger, will stand up for his family.

Alpha Supreme - Relatively quiet but not as much as Omega, calm, tactical, is sometimes the voice of reason, cares about his family and will stand up for them.

Beta Supreme - Cares about his family, relatively quiet, surprisingly he can be a little shy at times but will stand up for his family.

Gamma Supreme - Boisterous, likes to tease and have a laugh, a bit loud at times, cares about his family, says it how it is, will stand up for his family, is prone to swearing.

Delta Supreme - Likes to have a laugh, is relatively talkative and is Beta's voice sometimes, cares about his family and will stand up for them.

Epsilon Supreme - Relatively talkative, cares about his family, likes to tease every now and then, will stand up for his family.

Zeta Supreme - Boisterous, loud, likes to tease and have a laugh, says it how it is, is prone to swearing...a lot, cares about his family and will stand up for them.

Eta Supreme - Likes to have a laugh, likes to tease every now and then, cares about his family and will stand up for them.

Theta Supreme - Likes to tease every now and then, likes to have a laugh, cares about his family and will stand up for them.

Iota Supreme - Cheeky, likes to tease and have a laugh, cares about his family and will stand up for them, talkative.

Kappa Supreme - Sweet, cares about her family, a little talkative, will stand up for her family, a little sensitive.

Sigma Supreme - Chatty, bubbly, likes to tease and have a laugh, serious in battle, cares about his family and will stand up for them, is the unofficial favourite of Ultra Magnus.

Ultra Magnus does respect all the Autobot Guardians, but he has a soft spot for Sigma, which is no secret amongst the Guardians.

So I think that is everything, if you do have any questions, feel free to either PM me or leave a review, thanks for reading! The first chapter will come after this :D
