User blog comment:Raul123alin/My theory about the origin of the titans/@comment-1784834-20141116075446

I say it was the Angels from Neon Genesis Evangelion. They appeared, NERV got its ass kicked, Shinji and Asuka escaped into subspace, and the rest is history. And the Evas? Shinji and Asuka deserted, leaving Rei as the only available pilot. She was defeated by the original Colossal Titan and eaten. And then her DNA was used to enhance the Titans. And the rest of NERV (Gendo, Misato, Ritsuko etc.), they were all made into Titans, though the females were quickly taken out during the 1st Survey Corp. Expedition.
