With the situation neutralized, Optimus would be freed to focus on more pressing matters. Notably, the battle his allies were currently fighting. However, he didn't get more than a couple steps before some other being addressed him. Seeing as how it didn't want to fight, he deactivated his blasters. Though he was far from defenseless, it would at least show he wasn't hostile to an apparently neutral party. Not to saw he wasn't on guard. He could easily react should hostilities begin.
"I am Optimus Prime." he returned the beings greeting. Though he would sound terse, it was not without reason. He did have a battle to fight, and there was little time for distractions. He did, however, have to admit that this being before him seemed to admit a peaceful aura. To further this case, he had witnessed the being heal his previous opponent, although that could also advocate for it being a threat as well.
