Crimefighting with Cash: One of the earliest and greatest examples. Oliver Queen is one of the few superheroes whose original motivations for fighting crime basically came down to "Because I'm Bored and Because I Can". He later found more noble motivations, though. And in the most recent retellings of his origins, he always had a noble heart and a desire to help people.
Expy: During the Golden Age, he was given many similarities to Batman, right down to the Arrow-Car, Arrow-Cave, and a teen sidekick in Speedy (who is really just like Robin only a junky).
On the bright side, The Flash was able to adapt it into a weapon for fighting Captain Cold.
However, Batman is able to eat it with a smile on his face and just go, "Hrm...it could use more crackers."
Millionaire Playboy: Oliver Queen, for much of his history. When his fortune was stolen from him in the 1970s, it fully completed his shift to the liberal man of the people. He's regained money lately, but as the head of a number of charities.
