Angel Dust (Hazbin Hotel)

Canonically gay, has had (mostly toxic) relationships with men.

Pepe Le Pew (Looney Tunes)

Pepé's personality and dating life changed over the decades, and that's not only him having toned down from obsessive to just very flirty (a good change). While originally he showed interest only in what he thought was a female skunk (most often Penelopé the Cat), fairly early he also started including Sylvester as an object of his desire too (Sylvester in these scenarios never had a female disguise, just skunk). Over the years, his focus on the species was more and more ignored as well.
While these could still be argued to not be canonical due to disguise and the joking nature, in his final canonical appearance in the early 2020s, he openly flirts with Yakko Warner (not in disguise, drag, or anything like that) who accidentally kissed him. Pepé did not mind that and just commented it goes a little fast. Considering this was from a time when cartoons featured more and more canonically LGBTQ characters and fan accounts analyzing characters' sexualities, we can read this as canonical confirmation from Warner Bros. that he's bi, maybe with a female preference, but still.
I hope we can bring Pepé back with a more updated, modern personality. He could still be a flirty character who respects boundaries. Considering he's a bi icon, it'd be a loss not to. I also just like the character.

Chazwick Thurman (Helluva Boss)

Like many characters in the Helluvaverse, Chazwick Thurman (a.k.a. a high contender for the title of scene-stealing one-off character of the day most deserving of being a recurring character of the 2020s) is LGBTQ+.
In this case, he's pansexual, having had at least flings if not full-blown relationships with all 3 protagonists (2 men and 1 woman).

Virgil Pigsdy (The Pigpen)
