Their Importance: Jem was an extremely popular cartoon and though I didn't grow up in the 80s, it's now a cult show. One thing I noticed was how many minorities this series featured as main characters. (characters like Ba Nee, Regine Cesaire, and Krissie were not included on here or the list would get waaay too big). Aja is a logical woman and has great mechanic, leadership, and deciphering skills. Shana is a rare example of a feminine black girl, being a fashion designer and loving the colour purple, but is shy and can snap at people a lot due to insecurities about people judging her or thinking her designs are ugly. Raya is a very shy and girly Mexican woman who later becomes the drummer of the Holograms, replacing Shana. and is loyal to her friends. Rio is Jem/Jerrica's boyfriend but is severely unlikeable in terms of his rudeness and he is fairly toxic to Jerrica and hates deception but can't tell Jem is a hologram of his girlfriend. Pizzazz is the lead singer of the rival band, the Misfits, and while she was mean for most of the series, she started to mellow out in season 3 after falling in love with Riot of the Stingers, and later helps Jem rescue Ba Nee from danger and they all make up. Roxy is a stereotypical "passionate, tough Italian-American" and hates Jetta with absolute fury. The episode "Roxy Rumbles" shows us a more sympathetic side of Roxy where we eventually learn she's illiterate, and by the end of the episode, she learns to read.
