Despite her trademark optimism and innocence, Ki has been show to act upon a more aggressive, competitive, and even devious side of her personality on occasion throughout the series. In Season 1, Episode 6, a day after Brian's embarrassing defeat at the hands of The Law, Ki ruthlessly defeated their teacher in an unnamed fighting game after she joined in the mocking of Brian. Also, in Season 1, Episode 7, although her intentions were pure, Ki went behind Ted's back and switched their school ID cards, causing him to sign her up for his father's rhythm gaming tryout while she signed him up for Drift Racing, which he had not wanted though later forgave her for.
- Her name is likely a reference to Kimberly Pine of "Scott Pilgrim vs. The World".
- Also, "ki" is the form of energy in "Dragon Ball Z", a refrence to her stating that her parents made a fighting game.
- At the end of Episode 8 when Ted is apologizing, Ki shoved Ted in the chest, and Ted swung right back, from hintings of the sound effect, Ted is being portrayed as the Gomboc: He has picked himself up.
