I'm so glad you enjoyed Warrior! It's a fantastic show for so many different reasons :D
As for some other shows, here's some that I'd recommend:
- The Legend of Korra: POC bisexual main character with another POC bisexual character. Huge for representation, but it's catered to a younger audience so different from Warrior.
- Person of Interest: It's been ages since I watched this, but Shaw is a POC and bisexual. I remember really liking it when I was younger.
- Sense8: Unfortunately this show didn't get the marketing and ending it deserved, but still very interesting and explores the whole spectrum of sexualities and genders.
- Blue Eye Samurai: This is a new show that's filled with action and character driven plot. It's enjoyable and the sexualities aren't canonically stated, but there's clearly queer shit happening. Very mature version of Mulan if it were set in Japan and were more explicit.
- Wynonna Earp: Waverly is bisexual and she's hot so...
Here are some added shows that I've never watched, but know there's action and bisexuals: Killing Eve, Lost Girl, The 100 (but like... bury your gays), She-Ra (I think), and The Shannara Chronicles.
