Brick Flagg

Brick Flagg is the star quarterback of the school football team. He once thought Kim liked him, due to a fraudulent story Ron wrote for the school newspaper, as seen in the episode. Despite being cast in the role of the stereotypical "dumb jock", Brick does manage to avoid being cast in a "school bully"-type role. In fact, aside from a confrontation he had with Japanese transfer student Hirotaka in the episode "Exchange", Brick typically does not make it a point to throw his weight around and actually seems to be a genuinely nice, if slow-witted, guy.

Personality
For most of the first three seasons, Bonnie Rockwaller was his on-again/off-again girlfriend, but it didn't seem to be a genuine attachment, as in, he showed some interest in Kim's friend, Monique. By , he had apparently dumped Bonnie, now that he was in college. During that episode, Ron called him and tried to convince him to get back together with Bonnie, to which Brick informed Ron that he had no intentions of resuming a relationship with Bonnie. Ron also realized during their conversation that college had actually made Brick much smarter.

In , a bald and fat future version of Brick Flagg was seen. He looks similar to the future Beast Boy seen in the Teen Titans episode, How Long is Forever.

Brick was initially stated to be only a year older than Kim and Ron, according to a press release, but he seems to be much older than that, because at the beginning of Ron's senior year Mr. Barkin stated that, "after seven years, Brick Flagg graduated last June", although it is uncertain if seven was the total number of years he was in high school––indicating he was held back for three years––or the number of times he failed to graduate––meaning he was in high school even longer; none of which addresses if he was held back in any of the other grades.

In the episode, , he was in the same Driver's Ed. class as Kim, Ron, and Bonnie. He kept crashing into the cones, rather than try to avoid any of them. He was also in the same class as Kim, Ron, Monique, and Bonnie in the episode, , he was partnered with Bonnie, which may have been when they began dating. There's also an apparent continuity error between   and   since in the first episode Brick is running for class president against Kim, but in the latter he's stated to have graduated before Kim.
