Rise of Galvatron by Deadeyes

Optimus has returned to earth, finished with what he needed to do. He has discovered that another Legendary Knight is still alive: A large set female with black metal and a sword and spear. She and her crew of new Autobots have joined Optimus and his crew. She has brought a new medic and weapons specialist. Titanius, the new and quite stubborn medic, Bull, the huge Autobot with a sort of deer skull like head and only his fists do the fighting, Dreads, the gun-crazy weapons specalist, and Nightfall, the Knight. Their fights may tear their trust in each other apart rather quickly.
