User blog comment:Xxkiiroxx/"Marco is Alive" Theory/@comment-10733658-20141004052737

Wow, that is some pretty extensive hunting down of theory posts. Bravo.

Conspiracy theories are fun, but ultimately we know that Marco is dead. Isayama has discussed his death in interviews, stating that he originally intended for Marco to live longer in the series. But he felt Marco's personality really didn't stand out among the cast, and decided to kill him off early.
