(I love this thread. We're all talking about Kakashi's good points. <3 )
We can't forget chidori. For one thing, it is an elemental technique and for Kakashi to be able to configure his own affinity into a technique of his very own is amazing, not to mention he was like... 13.
I recall that Kakashi said he made the chidori because he couldn't fuse his affinity chakra with the rasengan. That also means he mastered rasengan before he was 13. WOAH.
Well, he did manage to take down two of Kakuzu's hearts with help, but he wasn't doing too awesome. Still, that doesn't make him any LESS awesome.
People mentioned it prior, but Kakashi graduated from the academy at the age of five and became a chunin when he was six. That's VERY crazy. And he also became an anbu leader. Judging from the pictures, he was probably in his late teens or early twenties. That's pretty amazing as well.
He was acknowledged by Minato in the fourth shippuden movie and was taken along Minato's freakin' anbu team when he was just TEN. TEN man... (Okay, he didn't do much, but for the third to comply, that just shows how talented Kakashi was.)
I know Kakashi lost to Itachi in the first part of Naruto, but Itachi came back to warn Danzo that he was still alive. He took out Kakashi to show how strong he was... being able to take down one of Konoha's best.
Kakashi can practically use all five elements. (If you compile from the anime, manga, and video games.)
When Kakashi fought Kakuzu, he was able to bring out water in an area where water wasn't available. (I think) to do so, that person has to have precise control over that element.
Kakashi's awesome and he has looks to back him up.
WHAT NOW TROLLERS?!!!
