Well, there's Arbitrator, who's giving a good demonstration of what he's like further up in the thread (spoilers he's a real nasshead).

The Director - Who I think a lot of shippers are already familiar with. She always seems super professional but I bet she really is a giant romantic at heart.

Thad (or Inertia now) - Don't know if this one counts since he was here before. Don't know much about him myself. Mostly sticks to himself (I wonder if he's upset that Ladybug and Sovereign are both gone).

Valeria - Adorable but also way too much like having another Brainiac on board to be honest. Shippers leave her alone! She's way too young for that nass.

Archangel - Another that I think a lot of shippers are already familiar with (and with good reason, if I do say so my self). I was there for his beat down against Arbitrator and Umf!

Haven't heard much about Kimaris or Siegrune aside from names and faces, but they are both really attractive for humans, I can tell you that.

Zenyatta - Seems really nice but (and I kind of hate myself for this) after everything with Babbage I have a hard time really being around him. It's nothing against him, and I'm trying to get over it, because I know it's totally ridiculous, but still, yeah.

Bedrock - Any ARMORBROS shippers in the house that can help me out with this one? Still too new for me.

I think I might be missing a few others (or they might have been taken back home). But those were the ones I could think up off the top of my head.
