Ooo, yes I like this! I was thinking of Quark being more of a "villain," but a very small time one who uses his powers for personal financial gain and not any major villainous activities. I really like the idea of Quark having super hearing! He would use it to trade in secrets and further his profits, but he would also tell Odo about any significantly dangerous issues he should know about, and Odo would sometimes have to recruit him (reluctantly, lol) to help him with missions. (The Batman/Catwoman dynamic is right on the nose!) I imagine Odo is more of a loner superhero, but he does manage to make friends with some other superheroes who absolutely do not understand his obsession with small-time crook Quark. Anytime anything bad happens, Odo immediately suspects Quark, even though everyone else is like, "This is way bigger than Quark. I don't think it's him." It gives Odo the chance to rough up Quark a bit before actually questioning him to find out if he has any useful information. Ngl, I'm a little in love with this idea now lol. 🥹😆
