So, we've already had threads debating things like "Why is Steve Trevor such a hard sell?" and also "What can Steve Trevor be the best in the DCU at?" (Both are very interesting threads on these boards and are well worth a gander or two).
But I think there is an as-yet unexplored route to go with Mr. Trevor that could most clearly separate him from his perceived mediocrity: a dedication to pacifism that exceeds even Diana's.
Now, this is comic books, where violence not only sells, but is part and parcel of being a super-hero. Wonder Woman will not, and should not, flinch from dealing with supervillains in a violent way if push comes to shove.
But what if Steve is the one always seeking the most non-violent resolution to things? He would, rightly or wrongly, view violence always as this avoidable thing. This is one rare area where he could exceed Diana without necessarily diminishing her agency.
Of course, this would require changes. Big changes for Steve. Steve Trevor would have to stop being shown as a 2nd-rate Steve Rogers (the other blonde military guy who hangs out with superhumans).
Steve would have to get out of the military/espionage complex altogether and join something akin to the Peace Corp or Red Cross or something. Maybe convert the Oddfellows to an emergency response team to medical / natural disaster areas.
And while he can competently defend himself (sans guns), he is much more of a negotiator than a fighter.
I bet this idea for Steve wouldn't have many supporters among WW's already-fractured fanbase, at least not initially. But I think following any kind of "macho" route for Steve is doomed to fail.
What do you think?
