@Real Music,
These are the ones I haven't heard of before. Then again, I have very little experience with the comics themselves and most of my experience of the characters comes from the MCU as well as YouTube speculation on what characters could possibly come into the Disney+ TV series and the MCU movies. I grew up on limited DC Comics - mostly Batman. Make of that what you will.
I googled everyone to see if I could recognize the character even if I hadn't recognized the name.
