More diversity in sci-fi webcomix? Yes please: Athena Wheatley, or Warp & Weft features a black female scientist from the 19th century time-travelling to 9283. Fun, and looks good: Moebius meets Futurama meets Adventure Time (and sexy too! occasionaly cartoonishly NSFW)
A 1926 Brazilian sci-fi novel predicts a U.S. election determined by race and gender. O Presidente Negro envisions the 2228 U.S. presidential election. In that race, the white male incumbent, President Kerlog, finds himself running against Evelyn Astor, a white feminist, and James Roy Wilde, the cultivated and brilliant leader of the Black Association, "a man who is more than just a single man ... what we call a leader of the masses."
