Mega-Octane is the cool, calculating leader of the Combiners. He is cruel and unfair, and uses his four subordinates as if they were his own limbs - he expects them to carry out his orders without question, and he has no tolerance with delays or mistakes. He is somewhat envious of Scourge, who snatched leadership of the Commandos directly from him. In missile trailer mode, Mega-Octane can launch missiles with a range of 65 miles (105 km). In robot mode, he carries a laser rifle. He can also transform into a combat station and perform maintenance on his teammates. He forms the torso and head of Ruination.
