Please start filling out the "reason/additional/other reason" drop-down and input fields when making deletions. It helps us all keep better records of our actions. I'm not disagreeing with your deleting the Man of Steel, Gal Gadot, and other pages (it's too early for them anyway and not exactly how I want to optimize contribution to the upcoming movie), but filling out these fields when doing so will foster clarity and transparency for visitors and follow editors alike.
Also, the Wonder Woman Wiki will soon be undergoing a streamlining in category tree structure, article indexing and overall indicia. Our primary focus will be on written content. This means no more "image-dumping" - our Wonder Woman wiki needs to grow with information, not just pictures of comic book covers. It would be great if we started adding written content to pages that need it. Also, search engine optimization (SEO) will be a primary factor in raising web-awareness for our wiki.
My own personal "TO-DO" list consists of whipping the Lynda Carter series section into shape (something I've fallen away from this year), so I'll be jumping back into that area soon. But I'll be looking over the entirety of the wiki to see where improvement can be made for the written word. If you have ideas, I'd love to hear them.
I agree that we need more information as well as images but the comic book covers are relevant too as they relate to the current stories featuring the character in the New 52 so each month we update the latest issues featuring her. I will eventually go through the New 52 volume of Wonder Woman and make sure all character articles are made and up to date.
