I liked it. A bit fast and slightly lacked emotion in a few places, but maybe it's only me. I guess I've been reading far too many stories that are categorized as angst and tragedy. :D

Nice story, but Ben had better be ready to fight without the omnitrix, his enemies will still want revenge.

Didn't like the way you chose to get rid of the Omnitrix. You could have elucidated more as to why it came of so easily and what caused the malfunction in the first place. That right there is lost potential and would have made the story so much better. With that annoyance out of the way I can say that I enjoyed the story. Keep up the good work.

They didn't notice the Omnitrix was missing. Keep up the good work!
