@IS6A6E Hello, I hope I can help you too. Of the ideas I can offer, I could say that in order for Optimus to increase his physical strength and increase his transformation, you could make Mirko use weighted wrist and ankle bracelets. I know it may not make sense, but those wrist and ankle bracelets could weigh too much and Mirko would tell him not to use any of his transformations, which would depend only on his physique, while he trains hand-to-hand combat or is on patrol. Another thing would be for Mirko to teach him hand-to-hand combat or boxing strategies. Finally, Mirko can stop the nomu while Optimus arrives in time for Stain's fight.
