Mmmph...well, in this story I assumed that the Light robots have some sort of nervous system because they seem to feel pain in the shows. (And if they didn't, half the premise would be off--Rock wouldn't feel any pain at all, so the whole 'let's hurt him!' thing wouldn't really exist, ne?)
As to the helmet--if you remember in the Prologue I said that it had been torn in half from the impact.
Chapter Six
"Welcome to the Wily Show!" snickered a familiar voice as the holovision turned itself on. Roll growled as Wily's ugly mug filled the screen. She tried to turn the blasted thing off, but it only turned itself back on again. She nearly swore as the newsbeam invaded every single monitor in the compound, including the ones that were controlling the security system for the lab's defense, switching them off. Now she was the only robot defending Dr. Light—and though she was enough (she'd proven it numerous times as the Robot Masters tried to invade the compound) it meant she couldn't even try to get out and avenge Mega Man, which frustrated and maddened her.
Dr. Light only watched impassively. He seemed to not care, as though he had finally given up.
"Today on the Wily Show we have a special guest!" said Wily, bringing their attention back to himself. "And I'm sure you're all dying to know who it is."
The camera focused on a beaten figure.
The world stopped and stared, speechless.
"Yes," said Wily into the silence. "The one, and only…Mega Man."
Roll and Dr. Light stared at the screen in horror, and tried to put their thoughts together. Mega was there all right, but he looked…wrong. His helmet was torn in half, and his eyes wouldn't focus on the camera, as though he couldn't see it. He fidgeted uncomfortably, and rubbed his left arm with a pained expression as it accidentally hit the person standing next to him...someone horribly familiar…
Protoman.
"Oh, God…" Roll whispered. She no longer cared about Dr. Light's rule to never swear.
All she cared about was that her brother was in the hands of his worst enemies and she couldn't do a damn thing about it.
