Shockwave was doing an experiment. Trying to make a ray-gun that could change the gender of any bot. Specifically the Autobots. Him and Megatron both thought that most femmes were weak, so they were making this ray so they could change the Autobots and it would give them the upper hand in this on-going war.

But- Shockwave messed up… sort off…

Now the gun worked- but this kind of power came from the Allspark itself! So no doubt it was powerful. Too powerful one might say..

A battle was raging that day:

“Now Shockwave!” Megatron yelled the order across the battle field.

Up the top of a hill close by was Shockwave holding the gun. He set it too high and aimed it towards the Autobots- and fired. But the gun was too powerful and it exploded! As dust cleared up around the area- bots looked around. They then realized something… They were all the opposite gender then they were before!!

“What the!?!” Starscream yelped “Shockwave you dumbass! Look what’ve done!” Megatron yelled- enraged that her and her whole army were now femmes.

“Wow… this is new..” Wheeljack said- checking herself out. “AHHHHHHHHH!” Elite and Arcee both screamed. Realizing they were both mechs now..
