Joining Martian Manhunter in that particular tier, is none other than Oliver Queen, the Green Arrow. A member of the Justice League, although not a founding member. Originally conceived as a Batman knockoff, with his own Arrow-Cave, Arrow-Car and plucky sidekick. Ollie was actually rather bland, all things considered way back when. Then they decided to give him a cause and a lot of liberal guilt. He got a lot more interesting, although he really DID tend to call poor Hal a Nazi waaaay too often.
Ok, he's taken a few people out over the years. Permanently, but man...they DESERVED it! That old Justice League is just too judgemental. Things are always a lot less exciting when Ollie isn't around.
Ollie is for the "little guy", and abhors the "fat cats". He also can't seem to keep it in his pants, and has a way of messing up his private life with dull regularity. But what the heck, he's fun in a bizarre sort of way, especially when he starts ranting. And who wouldn't love someone with a boxing glove arrow, a tiny vacumn arrow, and a dead cat arrow?
Not the women, apparently. He's got Black Canary, although they seem to be on the outs lately. But that won't last. He's got a couple of sidekicks, and a slew of illegitimate children, but that doens't slow him down. He likes to play Robin Hood and he shoots people with pointy sticks.
He may be a Bridesmaid, but he's the kind of Bridesmaid that has a HELLUVA good time at the wedding.
