Despite being off, Jon wasn't exactly out of it. He could still feel enough phantom power coursing through him to do something, and he realized with everything going on, he might just be the best shot at saving the day. He managed to turn himself on and attempted to chase after Mikey.
Jon caught up just as Mikey was making his way outside. Jon was sure his brother had stopped to make a mess of things on his way there, but he could fix all of that later.
"Mikey!" He demanded, "Give that back to me now!"
"No!" Was Mikey's only response as he zapped Jon again along with another target: their sunbathing neighbor.
The most welcome part of the fusing was Jon's head was smaller. It was now about the size of an average person's. It was round. He had hair -- although it was now long blonde hair -- but there was still a plastic shell under that hair. His face was completely flat and still a screen, but he no longer appeared to have an off button and his face took up the entire screen.
The unwelcome change was to his body. He was now busty and definitely female. He wore a skimpy bikini as well. He seemed to still have his male body hair. It probably would've been a very awkward sight if not for the even awkwarder sight of his screen-face.
Fortunately, thanks to his wish, he was still thinking 100% like Jon, but in the time it took his body to change, Mikey had run off somewhere else.
