Redesigns have a summer public domain superheroes The Arrow, Hydroman (Hydro-Dragon), T.N.T, and Duke Of Darkness

I decided to redesign some public domain superheroes and for fun put them all on a team.

I decide to change hydroman's name because it is way too close to hydro-man from Marvel and besides it's kind of boring as a name.

Also I know I spelled darkness wrong.
