Boy Genius Dexter makes amazing invention after amazing invention including a time machine that his annoying sister Dee Dee first used in the first episode, “DeeDeemensional.” I enjoyed the way it ended.

When the evil Aku returns to threaten the empire, a young prince trains for years to eventually fight and defeat him, but before Aku can be fully vanquished, he sends the prince into the future where he battles through threat after threat (with stories told in pictures more than words) in his quest to return to his own time.
