 * Varies A LOT: Initially, Rukia is The Lancer, but leaves and is briefly replaced by Uryu, who returns to Smart Guy when Renji joins the team.

 * Varies A LOT: One of the complicating factors is that, aside from The Big Guy, Rukia has some elements of all five roles, acting as the informative partner-mentor to Ichigo in the Substitution arc, posing as the primary focus of the Soul Society rescue arc, and in the first half of the story, was the series' co-star, important enough to be considered as The Hero for her own personal character arc.
 * In the Arrancar arc, Chad and Uryū are replaced by Renji/Ikkaku and Hitsugaya respectively, and Rukia becomes The Lancer again.
 * In the midst of the Soul Society Arc, Hitsugaya briefly substitutes for Ichigo as The Hero, with his friend, Momo Hinamori as The Chick and lieutenant Rangiku Matsumoto as The Lancer.
 * In all OVAs and filler arcs, Rukia is The Lancer and Renji the Sixth Ranger.
