We need a new trinity or an alterna-trinity. The trinity is of course Superman, Wonder Woman, and Batman. They're great and fantastic but what I envision is taking those three personality types and taking away their superpowers. They would not longer fight world-threatening villains but deal with more day-to-day mundane sort of adventures, or at least things that seem more humdrum that what appears usually in the pages of Superman, Batman, and Wonder Woman's respective titles.
I'd like to keep their relationships platonic. Nothing screws things up like romance. Its okay for them to have romantic partners or friends-with-benefits, but no menage-a-deux ou trois involving two or more the trinity.
Yes, Batman does have superpowers even if he can't fly, isn't super strong, and does not have a golden lasso.
Maybe they could all be in mid management in the same industry but working for competing firms. I don't want the plot to involve some corporate conspiracy. I want there to be character development, dammit! Character not plot should drive the stories. Inner turmoil, I want to see inner turmoil and confusion. They shouldn't all experience exactly the same things in the same way but they should all have their ups and downs.
Is their room for other supporting cast (Lois Lane, Steve Trevor, Alfred Pennyworth, etc.)? Yes, but I don't want them to be identical or too similar to the characters they are supposed to be mirroring.
Now what would really be great is if these alterna-trinity characters could exist in the DCU and occasionally run into or spot one of the their super-powered counterparts. The super-powered trinity would know nothing of the other alterna-trinity.
I just like the idea of ordinary people being the main characters. I think that's what fueled this post.
