During the first two seasons, all characters in the series were voiced by LittleKuriboh, even the female ones, adding to the comical effect of the parody. A notable exception of this were the characters of Rebecca Hawkins in the regular series and Gary Stu in the Other Abridged Movie, which were voiced by LittleKuriboh's now ex-wife, Abigail, mostly referred to by her screen-name Safty. However, with the introduction of Noah and The Big Five in Season 3, a number of other YouTube voice actors, mainly from the group Team Four Star, have become part of the main cast.
