Their history mostly forgotten and assumed to be the last of humanity, the Eldian people have barricaded themselves within a walled city to keep themselves safe from the humanoid giant man-eaters called Titans. A century passed and the false peace the people lived was shattered when two apparent Abnormal Titans smashed through the two outer walls, resulting in countless deaths. Among the survivors was a youth named Eren Jaeger who dreamed to one day join the Survey Corps to see the outside world, and was consumed by hatred and revenge after his mother was devoured before his eyes. Following a hazy final meeting with his father Grinsha, Eren joined the Survey Corps while learning he can transform into a Titan. Eren and his allies soon find opposition both inside and outside while eventually learning the true origins of the Titans, as well as the advanced Marleyan civilization whom the Titan Shifters serve.
Power of the Verse
The verse is relatively weak. The strongest humans are peak human level in terms of stats. Most Titans have no intelligence at all and many are simply mindless beasts. However, some Titans, mostly Titan Shifters, possess a vast level of intelligence comparable to or exceeding an experienced and cunning human. While the Female and Colossal Titans display intelligence, the Beast Titans was able to speak perfectly in his Titan form.
The most dangerous aspect of the Titans is their unpredictability. They do not follow a strict set of guidelines and have seemed to increase in abilities and attributes as the series goes on. Due to their size, Titans possess enough strength to collapse buildings and when combined with this lightness, they can put on amazing bursts of speed and agility. In addition to their size, speed, strength and large numbers, Titans also possess incredible regenerative abilities - the only sure way to kill them is by slicing out the nape of the back of the neck. They regenerate lost and damaged body parts within seconds to minutes, most of the time severed heads as well but it has been noted that there are rare times when the head will not regenerate.
