(Optimus user)
A strange phenomenon has occurred. Infectious ones had bitten people, who then bit other people
You found yourself in a supermarket with your team; Ratchet, Bumblebee, Bulkhead, Arcee, Wheeljack, Smokescreen and Ultra Magnus; and obviously the supermarket was full of zombies
You headed towards the staff room, with the cameras. The door didn't open, but people were there
When zombies almost bit you, people opened up. And you discovered that it was: The Decepticons
Featuring: Megatron, Starscream, Knockout, Breakdown, Skyquake, Dreadwing, Soundwave, Shockwave and Airachnid
Okay...you end up pregnant by Megatron, really bad timing.
*That said, during the pregnancy you did well. *
Time skip: You were giving birth
Ratchet between your legs, Knockout wiping your forehead of sweat, Megatron holding your hand. The others were watching to see if the baby was coming or watching to see if any zombies were coming
You had a towel in your mouth to keep from screaming and attracted the zombies
Knockout:''You're doing great..''The red medic say Ratchet:''Push! You can do it!''Your old friend said Megatron:''Come on my love...''
