I've been binge watching Helluva Boss (again) and I think I've realized something about Blitzo. As much as we see him dom Stolas and try to dom everything sound him, I think he likes being dominated more.
(Yes, I'm analyzing the kinks of a fictional demon)
Let's start with the Striker and Blitzo scene from episode 5.
Striker pinned Blitzo against the wall, and Blitzo mentioned how it was "kinda hot." He also smiles while saying this, and he seems pretty into it. And while you could say that it was acting, some parts of the scene seemed genuine (including contemplating joining him).
And off topic here, it's also the first time I realized how long Blitzo's head was. Looks like a potato or a pickle.
The next scene I wanna talk about is in episode 6, specifically how Blitzo reacted to Stolas in the little drug trip and how he reacted when Stolas saved I.M.P. I won't br full blown analyzing the drug trip (many videos doing that, I recommend watching Cartoon Universe's one).
In the dream, Blitzo crawled towards Stolas up golden stairs that were cleaned off by his feathers. A chain goes around Blitzo's neck when he reaches him, and dream Stolas puts a finger on his chin and pulls Blitzo forwards with the chain. While I don't think this is supposed to be a, "Blitzo turn on" scene, I do want to mention Blitzo's little blush. He also doesn't seem to try and leave it, but he's embarrassed that he doesn't want to leave.
And then the scene where Stolas saves I.M.P.
Blitzo's face isn't fear or complete shock. It looks almost like admiration. He's in awe that Stolas went into his full demon form, just to save him. He likes that Stolas went in full demon form to save him.
An honorary mention is Verosika Mayday, who is a tall Succubus that is definitely a top.
And now "Seeing Stars." This one kinda just proved this head canon to me. Especially with that. "BReaThlEsS" scene.
This is the first time we see Blitzo actually appreciate Stolas's advances. And it's when Stolas is acting like a dom. Usually, his flirting consists of "in your face" comments or just the most horrifying, nonsensical, kinky dirty talk ever (wtf is he gonna do with jelly sandwiches???). But the flirting here is a lot more subtle, and Stolas having complete control over the situation. Which was definitely a turn on for Blitzo. I think that Blitzo does enjoy being dominate most of the time but, to me, it seems like he's a switch.
It also make sense why he'd like being dominated at times. He feels like he has to do everything by himself (said in the "Truth Seekers" dream), and is probably used to doing everything by himself. Makes sense that he'd want someone to be in charge for a bit.
(Aka, I wanna see dom Stolas or power bottom Stolas. It'd be awesome)
