Plate · 001TIT·001TitansFeaturedWho are the Nine Titans in Attack on Titan?The Nine Titans are nine distinct powers, each with its own form, size and ability. Unlike pure titans, whoever inherits one keeps their human mind and chooses when to transform: they are weapon, symbol and sentence all at once.11 minRead entry →TIT · 2 entries
Titans
The power split into nine, and the bloodline that inherits it.
- TIT·002Titans
Plate · 002Who are the Subjects of Ymir, the Eldians of Attack on TitanThe Subjects of Ymir are Ymir Fritz's descendants and the only people who can be transformed into titans. Beyond Paradis, different states identify them as Eldians; Marley confines them in internment zones and uses the possibility of transformation to justify segregation, military recruitment and propaganda.14 min - TIT·003Titans
Plate · 003What is the Ackerman clan in Attack on Titan?Two of the show's best soldiers share a surname and are not close relatives. That coincidence, which reads as chance for dozens of episodes, turns out to be the tip of an entire bloodline: people with titan strength who never become titans, and whom the power that governs everyone else cannot touch.11 min

The world
The walls, the land, and the machines humanity survives it with.
- MUN·001The world
Plate · 001What are the walls in Attack on Titan and why do they exist?On a first reading, the walls are the colossal defence that lets humanity survive the titans: three concentric rings roughly fifty metres tall, sheltering the last known civilisation. That is the apparent truth Attack on Titan opens with, and it carries the emotional weight of the show's first half.11 min - MUN·002The world
Plate · 002What is the omni-directional mobility gear in Attack on Titan?Omni-directional mobility gear is the technology that lets Attack on Titan's soldiers fight in the air. It fires two anchors, reels in their cables and releases pressurised gas, turning buildings, walls and trees into pivot points.13 min - MUN·003The world · spoiler-free
Plate · 003What is the right Attack on Titan watch order?Attack on Titan is watched in the order it aired, and that is the short answer: four seasons, eighty-nine episodes, nothing reshuffled. The real question is not where to start but what to do with everything around the main run — the OVAs, the compilation films and the "chronological order" lists that circulate online.9 min

Institutions
The corps, creeds and powers that rule behind the walls.

Plot & ending
Why the story ends the way it does: choices, plans and consequences.
- TRA·001Plot & ending
Plate · 001What is the 50-year plan in Attack on Titan?The 50-year plan is the long-term deterrence and modernisation proposal presented to Paradis. It combines a limited demonstration of the Rumbling with Hizuru-backed industrial development, but depends on a royal-blood succession that places the cost on Historia and her descendants. That bargain drives much of the conflict in the fourth season.15 min - TRA·002Plot & ending
Plate · 002What is Zeke's euthanasia plan?The euthanasia plan is the most uncomfortable answer the story gives to the question of how the titans end: not by killing anyone, but by making sure nobody else is born. It is Zeke Yeager's real objective, the one hiding behind the deal Paradis believed it had signed, and the secret engine of almost everything that happens in the fourth season.12 min - TRA·003Plot & ending
Plate · 003Why does Eren start the Rumbling?It is one of the central questions raised by the ending, and a one-line answer hides the disagreement built into it. The Rumbling culminates four years in which Eren encounters diplomacy, deterrence and Zeke's euthanasia plan, rejects each option on different grounds, and moves towards destroying the world beyond Paradis. This article separates what he tells other people, what he admits to Armin and the part played by his future memories.12 min - TRA·004Plot & ending
Plate · 004How was Ymir freed? Who freed Ymir?The ending does not reduce Ymir's release to a broken lock or a single rescuer. Eren and Mikasa affect her at different moments, and the series leaves viewers to connect Ymir's choice in the Paths with the disappearance of titan power.11 min
