Bisexuality, despite being the third letter in LGBTQ, doesn't get a lot of recognition in the media. Shows, books, and movies rarely have explicitly bi characters. This is especially frustrating when they act pretty blatantly bi. Things are getting better with more and more characters being openly queer in general, specifically with the new movie "Solo: A Star Wars Story" confirming Lando Calrissian as pansexual. But there are a lot of characters I've seen and read throughout the years who may be unconfirmed bisexuals.
1. Michael Scott.
2. Leslie Knope.
3. Becca Mitchel.
4. Lily Aldren.
5. Rick Sanchez.
6. Tobias Funke.
7. Dean Winchester.
8. Poe Dameron.
9. Li Shang.
Shang was definitely into Mulan, but he was kinda into Ping also. It's possible he was just super impressed with Ping's abilities and the progress he made over the "Darkside of the Moon" montage, but I think it was a little more than that.
11. Chad Danford.
Chad clearly does dance. He also might like guys. It doesn't come up except in the second movie when Ryan challenges him. But after that scene, they switch clothes, which opens up quite a few speculations.
12. Jo March.
Jo March, from the novel "Little Women" was largely based on the author, Louisa May Alcott. There is some speculation on Alcott's sexuality and a theory that she may have been bisexual. I would say that if it counts for the author, it counts for the character based on the author. Winona Rider's depiction of her certainly does not help.
13. Kara Danvers.
Now, I haven't seen much of the show "Supergirl" but from what I have seen, Kara definitely has a thing for Lena Luther. The show tries to pair her with other guys in the cast, but it's nothing compared to the chemistry with Kara and Lena.
I would love for more shows to have confirmed bisexual characters. I think having more bisexual representation in the media would help end some the stereotypes and misinformation that bisexuals deal with. Also, we are awesome and would be great on TV.
