User blog comment:Raul123alin/My theory about the origin of the titans/@comment-76.78.3.39-20131012071034

Interesting. One thing i am almost sure of is that titan were created by humans. Also, one titan with the coordinate ability can order the titans to only eat humans, and that would happen. Also, human shifting titans are times more powerful than normal titans. One way to see this is that whoever created the titans was human and created it as a way of boosting our bodys, but he hated humanity or a part of it or something went wrong and a lot of humans were turned into titans definitively (the weak kind). So what we have can be a struggle of human shifting titans against humans, which makes sense since we had colossal and armored trying to break the walls. But they stopped by some reason, and by the looks i think they changed their mind about erasing humanity as they were infiltrated as spies into humanity. Most likely Eren's father is also a titan (since he gave the power to Eren) and one of the leaders, but as it seems he doesn't hate humanity. Where he is now and doing what is a mistery, but i guess that he's already dead or imprisoned for helping humanity. As we saw in Connie's village humans can be tranformed into the weak titans. If the ape titan is also a shifter, then he could be the leader of the human shifting titans. If he's the leader, then he may have created the titans and the powerful titans, and he's the enemy of mankind. That's my speculation about it xD
