Sidekick

This person is almost always with a partner called a Buddy. Sidekick tends to enjoy the company of Buddy's girlfriend or boyfriend. When asked, "How's it going?" the sidekick may respond "Not much"...(long pause)..."You?" The sidekick may either be in class, the computer lab, or working out. The sidekick may be more or less powerful than the Buddy, but they tend to train in some form of Karate.

"Looks like Sidekick just got back from working out."
"There's Buddy and Sidekick."
