Raven talked about her time working at MLP and there were a few things I found interesting
1) apparently Hasbro would not let the crew release storyboards, they were very strict
2) the crew was more or less upset about the Equestria Girl designs, they wanted the girls to be more diverse. human Twilight was originally supposed to be black but Hasbro (the ultimate evil) wasn’t very happy with this so to avoid the issue entirely they went with the rainbow color (and same model essentially)
3) in the wedding episodes Raven boarded the sequence in the crystal caverns + This Day Aria
4) (technically not FiM related but sorta) she did a voice role in Friendship is Witchcraft but is uncredited
5) Unlike EEnE and SU, where the boarders write the dialogue, for MLP the boarders got a super long audio track they would cut into pieces and board around (makes sense because Tara was recording her lines from Cali while everyone else was in the studio in Canada)
