Seems as a few of my DC concepts yesterday seemed surprisingly popular, here's a couple of ideas of mine for the other side of the fence: Marvel.
The Great Lakes Avengers would be such an interesting look at the... well, not even second, more like eighth-stringers of the Marvel universe, and seeing them in a comedic series following their exploits as this group of marvellous misfits try and protect Wisconsin and the surrounding areas as best they can. There's so many pieces of the comics that would lead to humerous scenarios, too - be it them having to carry cardboard cutouts of Squirrel Girl after she left them due to their ineffectiveness, to the running joke of heroes known as the Grasshopper dying within seconds of joining the team, or even their forced rebrands over the years, all of them would be amazing.
The Agents of Atlas is, in my personal opinion, one of the single most interesting Marvel groups out there... even if the MCU would struggle to handle them given their 50s origin and the fact that Jimmy Woo, in the MCU, is a very modern person. An ensemble cast of various Marvel characters from the 50s specifically, in the throes of the Cold War and shining a light on an interesting and rarely-observed period in superhero media, I think this would be fun to see - as well as giving us a lot of really unique concepts to play around with, such as M-11's retro-futuristic arsenal and Gorilla-Man's... being a gorilla.
Triathlon would be a great addition to the concept of the Agents of Atlas. The successor to the 50s-era 3D-Man, Delroy Garrett Jr. is a disgraced athlete who ended up turning to a cult known as the Triune Understanding for support at his lowest point. Being given the power of the 3D-Man's glasses, giving him the physical strength, speed, and skills of three men, I think this story - a more personal tale of a man trying to climb out of his lowest point whilst the whole world seems to be against him - feels like a really cool addition, and a great way to observe such a relatively obscure character.
Lastly, a concept of my own. Stick 'n' Slick, which would prominently feature relatively obscure villains the Trapster (also known as Paste-Pot Pete) and Slyde, who decide to work together to produce and fund the inventions of villains who never got the chance and turned to villainy for it. Starting by selling Peter Petruski's Patented "Perfect Paste", an instantly solidifying adhesive paste with incredible uses for construction, and Jalome Beacher's "100% Slyde-Approved Lubricant", which has a lot of uses for mechanical equipment and... other things, I imagine this show being set up with similarities to The Office, whilst also being able to set up relatively obscure or less-powerful heroes as "big-bads" - something rare in a lot of hero-based properties.
And as for characters? The possibilities are endless! I'm personally thinking characters like Rocket Racer, Stilt-Man, Beetle IV, Hypno-Hustler, Clash, and even weird additions like the Living Brain, would work really well here.
Hope these are at least somewhat of interest!
