Even the "Copy Ninja" Kakashi has lost his original gimmick and replaced it with a Mangekyou Sharigan that warps space and time, as Assertn has just pointed out.
First we're told that the Sharingan copies enemy jutsu, and that was cool. Several hundred chapters later we're being told that it can also control the Kyuubi. It's a pretty telling example of how the series has progressed over the years. Sorry for going so off-topic, everyone.
