- His name, when associated with Killa (a character seen discussing with Jewel very often during the 25th tournament), is a pun on the word "kilojoule" (a measurement of energy similar to a calorie).
- His style of behavior is very similar to both Caroni (one of Mr. Satan's disciples) and Nareg (a contestant in the 28th Tournament); all three are blond, and loved by women.
- In an art error, when he is carried to the hospital on a stretcher, he has a mark on his face as if he has been kicked there, but Android 18 kicked him in the chest, not the face.
