What you don't like on your favorite character

[Trea]

Jiraiya, dragging Naruto around to baths so he can spy on women. Using Naruto's money instead of his own. Leaving Naruto to train by himself while he went out to get "lucky" with Naruto's money. Couldn't obtain perfect sage mode. He is my favorite character and he was good comic relief but he did look ugly in sage mode.
