6. Deadpool (He's the first thing I've ever seen die and come back, in fact, he's the first time I've ever actually seen a superhero get killed. He's not the first supehero I've seen that's killed someone, however. That one goes to the Punisher.)
5. Captain America (It was surely a shock, but not too sad. Of course, he came back when I least expected it...)
4. Thor (Because I didn't think it was possible!)
3. Eddie Brock (Because he was the best Venom, IMHO)
2. Gwen Stacy (She's not a superhero, but she's the first good person that's actually died in comics. 'Twas very sad.)
1. Superman. (I hate him, so I loved every second of Batman murdering the shit out of him.)
