Thor woke up three days later feeling different then he had ever felt before. Very, very different. Soft. Weak. Small.
In a panic, he opened his eyes to find the Avengers standing over him with curious expressions on their faces. They looked somehow looked shocked, amazed, and horrified at the same time.
"What's happened?" Thor queried, noticing that his voice sounded different, too. He knew something was extremely wrong when Bruce burst into tears and shouted an apology as he ran out of the room. Tony looked very sad.
"Here," he said, and he handed Thor a mirror.
Thor sat up and took the mirror. The other Avengers heard a small gasp before Thor collapsed.
. . .
A few minutes later, Thor sat up in bed and said "Please let that have been a dream."
When he saw his teammates serious faces, he realized otherwise.
"What happened? Tell me!" he shouted.
Tony explained. "You went into Bruce's lab when he was experimenting with gamma radiation. He didn't see you until it was too late. You walked right into it. Thank god you weren't human."
"'Weren't human'?" Thor interrupted. "Of course I wasn't human!"
"I'm sorry," said Tony. "But the gamma radiation affected you strangely because your DNA was so different from ours. It turned you into a mortal. You are now physically equal to a human teenager."
