What character do you wanna see on a t-shirt?

So I recently started designing t-shirts here. I wanna know what you guys would like to see on a t-shirt w.r.t DC and Marvel characters. Also if anyone wants something specific, I will design it for you ( whether you actually buy it or not, doesn't matter). I'm not trying to advertise anything - I just wanna discuss what kind of t-shirts the community would like so that I can open myself up to those ideas and develop.
