While "Attack on Titan" season 2 is not expected to air in spring next year, various rumors and speculations have already surfaced online as to how the story of the anime series may pan out when it returns. However, there is no denying that one of the loudest plot theories associated with the anime series' upcoming season is that it will feature the death of Captain Erwin Smith.

According to rumors, fans must brace themselves for the demise of one of "Attack on Titans" fan-favorite characters, Captain Erwin Smith, who is said to die in the hands of the titans. Allegedly, the great leader and fighter of the 13th Scout Regiment will be killed immediately in the first episode of the anime series and will finally bid goodbye to the story and fans of the series.

As Captain Erwin Smith is not only a beloved character by the fans but also by his comrades, it goes without saying that "Attack on Titan" season 2 will be filled with grief and mourning almost immediately after its return. However, the death of Captain Erwin Smith will also trigger more action-packed scenes in the future as it is said that it will fuel Eren's desire to slaughter the titans. After all, Eren and Captain Erwin Smith have a special bond as the latter even lost a hand while saving the former in the past.

Apart from the death of Captain Erwin Smith, it is also alleged that the upcoming season of "Attack on Titan" will also shed light on the history of the titans. According to reports, the upcoming season will finally unravel the secrets hidden in the basement of Eren's father, Dr. Yeager, which will shed light on how the titans came into being.

Meanwhile, there is still no official date as to when "Attack on Titan" season 2 will really arrive to the small screen. Nonetheless, it is believed that the anime series will arrive within the months of spring next year.
