Using the names of the Toa @JediTimeLord824 picked but switching them to the ones who take the masks, as @UltimateMustacheX suggested, works incredibly well. Tuyet’s betrayal could be caused by a disagreement about taking the masks from the matoran, which instead of betrayal, could be looked at as a difference of opinion or even the defending of her peoples’ rights.
@Bokarda, if you need another set of Toa for a future pitch, I recommend maybe the other protectors from g2 as I don’t believe they’ve been used yet.
