why do so many heroes have *trusty side kicks* and what purpose do the sidekicks

[zinnprojectbig]

Side kicks are loyal.
Side kicks help the hero in times of need.
Side kicks sometimes ask the questions that heroes can answer.
Side kicks reminds heroes of what they need to do.

Heroes often have tragic flaws. Side kicks keep them on track.
