Mystique - Marvel
One of the coolest characters in the X-Men franchise, Mystique’s shapeshifty goodness and tendency to change sides makes her constantly intriguing. She is also bisexual, and happens to be the mother of Nightcrawler. Her longest and most substantial relationship, however, has been to be Destiny. Although the Comic Code Authority prevented the explicit depiction of gay characters for a long time, we learned the truth about Mystique and Destiny later.
