Don’t get me wrong, he should feel fear when he’s physically threatened, but WHY is he being physically threatened?! Before the new body, he could seemingly perfectly control Robot using just his mind/tech remotely. When getting the new body, he had the twins install the tech to continue to control them remotely. He even controls the giant one perfectly when fighting them.

So why is he putting himself inside the Robot suit now?! Fear of being injured or hurt threw him off his game, so why not go back to remotely/wireless control?! Seems like an easy way to stop being scared on the battlefield.
