Indeed.

It's been errata'd :
"The text of this card reads: “Before the beginning of each player’s first turn, that player chooses a team symbol possessed by an opposing character. The first opposing character with that team symbol that is defeated is worth additional victory points equal to half of that character’s point value.”"
(from the Player's Guide)

Arch enemies? Nah. Spider-man 3 finished them off.

Spidey and the new Green Goblin became buddies, then Spidey and Sandman had a bromance moment and practically hugged near the end...

You're telling me.

No freakin' Spider-Man 6: The Sinister 6

Honestly, that was so stupid killing off the original GG, Ock, Venom, and letting Sandman be Gone With The Wind.
