i really love this picture, the idea is reallly really awesome tho i have one thing i feel like i have to point out .. u got one thing wrong .. eren's body does not transform.. he just creates the titans body from the air and he controls it from the inside of the neck so actually he can't transform hes arm into a titans arm.. he just uses parts of his body to control the titan..
Jeah, i guess Eren can be accepted as different. And remember: The "normal" (real?) Titans STILL go after him, even if he is inside that Titan(body) - and still want to eat him and attack him, as soon as he resists to get eaten.
Why would they go after him, if he "is" a Titan? It was stated several Times or at least one, 'big' Time, that Titans NEVER attack their own Kind. Well okay, the 'abnormal Ones' may would do, but not Titans in General.
AAA~NNN'D: They want to "eat" him they don't just fight back as if they would be willing to brawl with him. They see him as "Prey", NOT as a fellow Titan. But they don't see their usual fellow Titans as Prey. So that should make Things more clear.
i agree totally with you and in my opinion other titans considering Eren a pray is a good thing ( for viewers at least xD .) Because it would be seriously boring if they wouldn't attack eren. When eren starts doing hand to hand combat with other titans (i love these parts) .. just that makes this anime like 100x better.
