Raymond Holt (Brooklyn Nine-Nine): Instead of being a classic "gay black man" character, he's a very strict police captain with a desert-dry sense of humor and an occasional flair for drama when he wants to be petty. While his sexuality is sometimes incorporated into some gags or storylines, it's far from his domineering trait. Gustavo Fring (Breaking Bad): I haven't seen Breaking Bad so I can't quite say, but from what I've been told, Gus could basically be a straight guy and the story wouldn't change. I didn't even know there were gay Breaking Bad characters until this post. Undyne the Undying (Undertale/Deltarune): You don't actually realize Undyne is a lesbian unless you go for the more pacifistic option and watch her date Alphys. You could play undertale start to finish and never realize it, but the ship between the royal guard & royal scientist is one of the best in game.
Dude, Raymond Holt being gay is central to his character. He struggled up through the ranks of the NYPD as a openly gay black man and that fact routinely backs his actions where he uses that experience to choose fairer more equitable choices over petty or self interested ones. He regularly cites his sexuallity as being core to who he is. While it certainly doesn't encompass his entire personality because all of Brooklyn 99's characters contain layers and multitudes it is undeniably central to his theme.
He just doesn't present as a stereotypical gay character.
