In season four, when they are officially dating, Ron struggles with his insecurity regarding Kim. He even goes as far as to steal her super-suit so he can become the school quarterback because of Bonnie's declaration cheerleaders have to date jocks. Though that backfires, he ends up as the football team's running back because of his "mad running skills" from all the running he does on missions. Ron ends up with a baby sister from Japan named Hana during season four. She has a mystical destiny, for which Ron is supposed to train her. During graduation, Ron is finally able to fully tap his Mystical Monkey Powers to a terrific extent when he single-handedly defeats Warhok and Warmonga when even Kim and Shego combined could not. It is unknown if his control of his Mystical Monkey Powers remains or returns to how it was. However, his confidence is boosted by the event.
