The second season of the most watched "Attack on Titan" was announced to be delayed yet again. Reports say that it will be available by next year, an extended wait for fans.
The Season 1 of the anime "Attack on Titan" has already included 34 manga chapters. These includes four story arcs: "The Fall of Shiganshina," "104th Trainees Squad," "Battle of Trost District" and "The Female Titan." The manga is only two story arcs ahead which causes the delay in making the second season of its anime.
It ended with the death of the female titan who turns out to be Annie Leonhart, leaving anime followers to ask how humans shift into a titan and where they get this kind of ability.
Spoiler ahead! Read at your own risk.
The following are from the Attack on Titan Wiki.
The 15-meter tall Armored Titan with yellow golden plates covering his entire body is no other than Reiner Braun. Reiner Braun is the 2nd in rank in his class, and a graduate of the 104th Trainees Squad. He is a former member of the Survey Corps.
The 60-meter tall Colossal Titan that lacks skin entirely and with a jaw and facial structure that seem to be heavily changed from the human form is actually Bertolt Hoover. Bertolt Hoover is the best friend of Reiner Braun. He is also a graduate of the 104th Trainees Squad and ranked 3rd in his class.
The Creator of the Wall is also a human with the ability to turn into a titan. He is named the First King and it is said that he has the ability to control titans, alter memories, pass down his own memories, and titan-shift.
Did you know? The three Walls, Maria, Rose and Sina, were actually hardened and enclosed Titans who were controlled and made into structures by the First King.
