Oh yes... replace that Titan with a giant badass robot, and you get yourself a Gundam series,
A young man with severe anger issues bears a grudge against a group known as the Titans that hatred is only intensified when said group ends up being responsible for his mothers death: Eren/Kamille
He joins the resistance group against them: Survey Corps/Federation
While there he is tutored by a war veteran who, though he doesn't look it, is far older than him: Levi/Char
Also there is his adopted-sister figure who at the same time is also a pseudo-love interest: Mikasa/Fa
MC father knows a lot of thing about the Titans/Gundam
Titan shifter/Gundam mech is a powerful weapon ridden by an elite few
One of the most powerful Gundam/meat mech is fallen into the hand of a young kid who's not been fully trained to use it
When you look behind the window dressing, Attack on Titan is really a giant mecha anime. A young boy discovers that he is the only one able to pilot a giant robot (read: “turn into a Titans(titan shifter)”). Moreover, his giant robot is also far more powerful than the other side’s standard giant robots (read: “normal Titans”), and he looks to be the key to turning the war in his allies’ favor. However, soon he runs into the enemy’s own special pilots—each who have his or her own super powerful mecha (read: “another titan shifter”)—that are intent on defeating/capturing him.
Yep. When it comes down to the general framework, Attack on Titan is basically Gundam.
