The combaticons were about to start their plan when the second giant appeared. "Combaticons, abort the plan!" Onslaught yelled, now trying to dodge the second giant. He could see no other solution than to combine. "We need to win this, Combaticons! Combine to form Bruticus!" He shouted. Swindle, now in truck-mode, drove up towards Onslaught, turning and formed a leg. Brawl followed suit, forming a leg from his tank-form. Onslaught transformed, he became the head and torso. Bruticus shifted one arm socket to the back, and Vortex latched on, becoming an arm. Blast Off did the same, and now there stood 80-90 feet of angry Cybertronia. Bruticus proceeded to punch the one launching red lasers in the face.

((I'm assuming Bruticus and Trigon are of similar height))
