Whoops, I missed the Death and Return of Superman one, which was short and sweet, and didn't have the hero suffer an identity crisis of his own "I'm me, but I'm not me, I'm not really me, he is the real me, me am clone, but no, me is me. WAAAAAAHHH"
For this round I will go with Screwball, who I initially thought for being a Roxxie Rocket ripoff.
