You were part of Project Predacon, you were in shockwaves lab when you woke up from stasis after the liquid that was around you drained, your vision was blurry for a while and your hearing was ringing quite a bit and your body was stiff when you finally gained your senses and looked around which you saw Shockwave in front of you with two other mechs Megatron and Starscream

Starscream: Oh great another beast…

Megatron: it’s quite Big (you can change the size if you want)…

Shockwave: Due to some malfunctions…its size is different

Megatron: Starscream, you will give command to this beast and Predaking understood

Starscream: Y-Yes Master

Soon after a while you were brought over to a kennel which leaded to the flight deck, soon you saw a black, orange and rusty red dragon with golden yellow biolights looking up at you

Starscream: Listen here Predaking, this is the new Predacon so I expect you to listen to me along with this beast

Soon Predaking huffed in annoyance soon you looked at Starscream confused as he was holding an electric rod and shocked Predaking but Predaking tossed Starscream across the room which worried you and you huddled in corner shaking soon he walked over to you and was standing up straight looking at you but since you were in your dragon mode (yes Predaking can transform in this version as well) you could understand him since everyone else can’t

Predaking: You alright, don’t worry your safe here
