So basically, Attack on Titan aka. Shingeki no Kyojin is by far the most mind blowing series of events, characters and anything else you can imagine i've ever had the pleasure of watching/reading. I recently caught up with what's released by reading the manga and i'm at a loss for words just because it exceeds anything i could have ever imagined for a series.

SO! SPOILERS AWAIT IF YOU READ ON. You've been warned

So much discussion and guesses can be made from what we know/don't know right now, and i'd love to share/hear other peoples views! basically, any view at this point could be right, or could be wrong.. we just have ZERO idea. anything can happen.

I took the time of doing some character study and putting some things together in my mind, also putting forth a very ideas myself

Note: Again, SPOILER ALERT. If you're not caught up with the MANGA, you should turn away now.


EREN:

in the beginning there is a cut scene of survey corps taking down a titan and then it cuts to eren waking up from a long dream, crying. he doesn't
seem to know why?

It mentions in the manga Ymir was outside of the wall in titan form for 60 or 70 years.. and then all of a sudden she shifts to human and joins the trainees?

is Eren just like Ymir? a titan shifter that was outside of the wall for many years before finally shifting to human? Was his dream in the beginning of the
series where he woke up crying him recalling himself as a titan subconciously?

Just before Eren awakes it flashes a few gruesome images .. children's toys, a house with a windmill, his mother being picked up before being eaten, and the
titan that killed his mother. Note, all of these flashes of image occurring before the actual death of his mother.

YMIR:

There is more to Ymir's character than we think.

Ymir in Norse mythology "" Ymir birthed a male and female from the pits of his arms, and his legs together begat a six-headed being. The gods Odin, Vili, and Vé fashioned the Earth (elsewhere personified as a goddess; Jörð) from his flesh,
from his blood the ocean, from his bones the hills, from his hair the trees, from his brains the clouds, from his skull the heavens, and from his eyebrows the middle realm in which mankind lives"

In the manga in the old, abandoned castle she was able to read a mysteriously language on a can that not even Reiner (the armored titan) could.

Outside the walls for 60-70 years before slipping into the trainee corps when the wall was breached by the collosal titan.

Her Titan is more feral than the others.

Strong attraction to Christa (part of some honored family that knows the secret behind why their are titans inside the actual wall itself)

WHAT WE KNOW ABOUT THE HAIRY TITAN:

The monkey titan has the ability to change humans into titans.
Which is why there was no breach in the wall, which is why connie's village people were mysteriously missing.. but one titan resembled his mom

Monkey titan had no idea what the 3d gear was and seemed very interested in it

He seemed to be able to command the titan's. (being able to stop them from eating someone, for example)



EREN'S DAD:

Alive or dead? we don't know.

Who is he exactly?

There is something very fishy about the whereabouts and significance behind Eren's dad and what he actually did. Also i feel their is significance to the mention
of a previous epidemic in the city eren's dad was regarded as a "Hero" for "curing"

We know the mysterious, hairy titan can indeed change people into titans. Is their a dormant titan gene in every human? Does this tie in with Eren's dad?

What exactly is in the basement that is so crucial to mankind that he could have possessed ?


Basically, their are three types of titans.

Annie, Reiner and Bertholdt- Skinless, normal ear'd titans that seem to have some sort of mission against humankind.
Eren, Ymir- They have skin, also pointy ears, and seem to oppose the other titans and side with the humans.
Hairy Titan- Seems far more elder and significant than the other titans. We know he's been away for what must be years since he had zero idea what the 3d gear was.
We also know he has the ability to change human into titans. We don't know what his intent is or who's side he's on.

Their is a popular theory suggesting long ago in their human history there were two warring factions. One of them turned their population into titans to combat
the other side, forcing them behind walls. The hairy titan could be part of this faction with his ability to turn people into titans. My only question is
why are their now good titan shifters, and bad?

Their is definitetely something interesting with Eren and Ymir's titans vs Reiner and Burtholdt's in a sense that it's the popular belief Eren and Ymir are both
titan shifter's that been around for 60-70 years or more outside the wall, before coming inside (confirmed for ymir, not Eren) We know that Reiner and Bert had
zero idea of the existence of Eren's and Ymir's titan's until they revealed the abilities. So what sets Eren and Ymir apart?


There are SO many possibilities we can hypothesize in regards to which way the story is going to go, we simply don't have enough information yet so all we have is
questions.

Could it be that titans are human created? I mean, Eren's dad seemed to have unlocked a lot of knowledge behind the titans.. could that be because he was involved
with this society that created the titans? It's not too far fetched of an idea, governments are corrupt, governments hide things. We already know their is a
cover up scandal with the titans being found inside the actual walls already. Maybe it was a past attempt to weaponize people against their enemy gone horribly
wrong and it bred mindless, people eating freaks, forcing them behind walls? Perhaps Eren was one of the test subjects that the doctor (his "dad") felt pity on
and brought home/raised for himself?

I think this is a POSSIBLE theory because look at the hairy titan, aka. "Monkey" titan. He seems to be the most intelligent and primitive of all the titans and far
more advanced. Could he be the first? because we know, with any experiment in our real world we first experiment on animals (monkeys) before moving to human
trials.
