Andromeda
Yeah, let's just say that Aquila wasn't too happy about finding out the truth. Here's what went down.
"Remember when you were seven you asked me why you were so different from the rest of us, except for maybe me?" dad asked.
"Yeah, what about it?" Aquila answered.
"There's a reason for that. You have mismatched parts because of me. Before I met your mother, I had this thing for upgrades and mods. You're still a little too young to get it, but mods and upgrades are highly addictive, like drugs. It took a lot for me to ditch them. So I gave it all up for your mother and siblings. But, the damage had already been done. The addiction over time had gotten into my data, or genetics, as humans call it, and, unfortunately, you were the first data victim to succumb to my mistake".
Aquila was speechless. "But dad, you told me you were clean".
"I am, now. I haven't been involved with mods and upgrades since you're sister was born".
"But that doesn't make any sense. The boys were sparked when you had the upgrade addiction. Why aren't their parts mismatched?".
"Their parts are mismatched, it's just not as visible because their colors go with each other".
"And Andromeda? What about her?".
"Strangely enough, her parts aren't mixed. Your mother's data is dominant in her circuits, so… it could skip a generation".
"And me being a beast morph? Where's that come from? Is that from you too?!".
"That we don't know. As far as I can remember, no one on my side was a beast morph".
"What about on mom's side?".
"It's impossible for that".
"Why?".
"She…she was human when I met her".
If Aquila wasn't mad a minute ago, she was now.
"How in the world did she become a Cybertronian then?!".
"It's complicated. She saved me from a fight which could've killed me. She took me back to her family's ranch two hours outside of Detroit, Michigan, where she took care of me. During that time…we fell in love. But I was also suffering from circuit cancer. When I died of it, your mother wanted me back desperately, so Idunne, the Cybertronian goddess, made her a Cybertronian and she placed half her spark in me, which brought me back. Your brothers were sparked about a year later".
"So what, I'm organic as well?! I'm like Blackarachnia?! A techno-organic!".
"You're not organic. Idunne erased all traces of your mother ever being organic when she turned her".
"What do you know? About your family, I mean. What do you know?!".
"I don't know much, seeing as how my memory core was erased when my mother was killed by some Decepticon renegades. I know that she was an Autobot and my father was a Decepticon. My father was killed in the war, but my mother, of course, was murdered. I was rescued by a bounty hunter named Death Gar, who taught me the ways of the hunter. I've been like that since".
"So now you're a half blood?! Dad, how could you do this to me?! This is your fault! You made me this way!".
"Aquila, it's not entirely my fault-".
"Oh save it, dad. I'm not interested anymore! I'm out of here!" Aquila transformed and flew out of the room.
Since then, life was never the same for any of us. We learned the same shortly after Aquila did. But the truth would also lead to the greatest adventure of dad's function. The best hunt ever.
