>>5265136For your Marvel Figures, why not a busy main street brawl. Instead of a the usual dank, dreary alleyway bullshit, have some vibrant, brightly lit storefronts, wrecked up phone booths, benches, fire hydrants, all that stuff. Make it bright colored, high energy, and comic booky.
Or hell even just a rooftop with a nice cityscape backdrop.
As for your Monsterarts and NECA stuff, I'd recommend looking into the Monsterarts Effect packs. There's three or so different sets I think, and each of them come with some little wrecked up buildings you could touch up with a little paint, beam effects, and even some scale military vehicles. Or you could go a little off road and make it a tropical setting, for a Monster Island thing.
