TIL (CW: Transformers, Trans Representation)
So, apparently, IDW's Arcee (from the long run that started 2008) is actually canonically trans.
and before I get yelled at, I know that run has problems, and isn't woke at times, but it's MY most enjoyed version of a toy commercial. The arcs and stories i love the most minimize human involvement and focus on the drama of a different society.
