I got back into Transformers so here’s my 7 oc sisters. Main oc is Eve in the way bottom.
they were the oldest Cybertronians that were task in guarding Cybertron. They have different models from everyone and aren’t able to transform. From the first to the last are from oldest to youngest and Eve is the only one that survives the fall of Cybertron.
When she crashes into earth, she is taken by M.E.C.H and was taken apart and put back together, transforming her into a disfigured autobot. The autobots soon found her and take her back. Only Ratchet has seen her actual face hidden by the wing plates. Miko calls her Evangelion due to her appearance and she just accepts it.
