The End Of The Universe IV.
Starscream, using his new Quintesson powers gained from his encounter with them, incapacitates the Transformers, thwarting any escape plans they initiate. While he judges some Transformers, Optimus, Bumblebee and an injured Wheeljack escape into the multiverse. Meanwhile, Windblade heads to Maccadam's, fights off the Quintesson Sharkticons and fully awakens Iaconus with assistance from Maccadam. In response, Starscream summons a brainwashed Croaton to attack Iaconus. Amidst the battle, Maccadam frees the captives before getting killed by a stray blast from Croaton. Starscream then uses Unspace to decapitate Iaconus' head and sends Croaton to destroy Iacon city. Optimus, Bumblebee and Wheeljack return from the multiverse and confront the Quintesson Scientist, with Wheeljack locating the Scientist's real body and killing it before Starscream attacks Optimus's team...
