User blog comment:Raul123alin/My theory about the origin of the titans/@comment-29395380-20160801082028

first it's starts from 1st king reiss.titans are definetly bio-weapons.

POSSIBLE SPOILER...girisha yeager  is not dead.there might be some memory whipping and constructing power similar to 1st king used on humans inside wall but in this case its used on eren and eren ate frieda reiss bcoz eren encounters only memories of frieda if he had eaten his father why would he need to find that secret in the  cellar where he can access in his father's memorie's.

someone stole this power from somone since we dont know and hid it behind those gigantic wall

and titans are simply trying to cure themself by consuming human's who can transform into titan.

for that they need large number for beating superior titan shifters.it's like finding willy wonka's golden ticket in those chocolate bar wrapper's by eating or unwrapping lots of bars but in attack on titan unfortunately chocolate bars are  humans and titans are participants and golden tickets are shifters.

the titan which eats shifter titan who stole this power( royal family most probably ) will transform and offered the place in shifter titan brotherhood like they did to ymir and eren.

intention's of bertholdt and reiner were not deadly towards ymir and eren they were like old buddies just reunited after sometime and they were calm as water when they approached to eren saying "we're armored and colossal titan".

and something is very wrong with people behind walls....im gonna really pissed off if it turns out to be matrix.
