(Spoiler)
Well, there is Maul. People compare both of them with each other. Though there really isn't that much to him yet seeing as he's just recently introduced. Though his debut certainly was popular. I expect we'll see more of him in the future.
There's also Barrel. Personally, I'm not into Barrel but he seems to have some content with a lot of fetishes including public humiliation, especially at the bar.
I can't honestly remember who else, but Maul certainly leaves a good impression for those who miss Gunnar.
