Although a release date for "Attack on Titan" season 2 has not been announced yet, fans are still excited about the return of the animated series. According to recent reports, season 2 will feature shocking deaths of major characters.

It is believed that Armin will meet his demise in the new season. Back in season 1, an unidentified creature was approaching Armin and it is assumed that this creature will attack and kill him. However, there are other reports suggesting that the creature would save Armin and help him escape his situation.

Besides the death of Armin, it is also rumored that season 2 will delve more into the history of Colossal Titans. According to Movie News Guide, fans will get to know how Titans came into the world and their origins as well.

Recently, a video of what is believed to be a scene from season 2 has been leaked. In the trailer, Hange and her squad have found out that a titan is living within the walls. Pastor Nick ordered the troops to kill the titan immediately and urged Hange to finish off the monster before it becomes active. However, Hange was surprised and persistently asked Nick to tell the truth as to why there's a titan inside the wall.

This is likely to pave way to the origins of the Titans as Hange will continue to dig in more clues to get some answers as to why the titan is inside.

Ymir will also be the highlight of the upcoming season. It is said that Ymir's story will be given focus since the first season didn't give much light to the character. He is said to hold a secret that should end the Titan mythology.

While plot rumors about the series continue to swirl, it remains to be seen when "Attack on Titan" will return. However, most media outlets report that "Attack on Titan" season 2 will return in the first half of 2017.
