Eren Jaeger's new powers were staring Attack on Titan fans in the face from the very beginning. In Hajime Isayama's Attack on Titan mythology, it's not difficult to figure out where the nine Titan-shifter names derive from. The Founding Titan started it all, the Colossal Titan is the biggest, the Armored Titan has a hard exterior shell, the Female Titan is the only warrior with an overtly feminine shape, the Cart Titan carries stuff, the Jaw Titan has a big mouth, the Beast Titan is hairy, and the War Hammer Titan paints tiny little figures. Eren Jaeger chiefly possesses the Attack Titan, which most would assume is named after its balanced fighting attributes - strength, speed, endurance, and hardening power.

Attack on Titan episode 79 tests the limits of how many canon-shaking revelations can be crammed into 25 minutes. Eren is taken on a tour of his father's memories by half-brother Zeke, and they learn details about Grisha that completely upend how we perceive events from past Attack on Titan seasons. Eren then pulls another surprise from his increasingly evil sleeve. Unbeknownst to even the Reiss family, the Attack Titan receives memory glimpses from future inheritors. That means Grisha knew what Eren would ultimately become as early as Attack on Titan season 1. Eren then exploited Grisha's Attack Titan future sight to manipulate his actions from the future.

The Attack Titan seeing events yet to pass has been hinted at previously - such as when Kruger (Grisha's immediate Titan predecessor) mentioned Mikasa and Armin years before they were born. Only in Attack on Titan episode 79, however, do viewers finally learn the full truth behind the Attack Titan's foresight power. Grisha's revelation may come as a shock to Frieda Reiss, Zeke Jaeger, and every fan who spent a year dodging manga spoilers, but clues have been pointing toward the Attack Titan's secret since Attack on Titan's very first episode.

Initially, the Attack Titan appeared to earn its title from those frightening combat abilities, but Kruger claimed otherwise in Attack on Titan season 3. According to him, "Attack" actually refers to how every single incarnation of this Titan pushes forward; fighting enemies, striving for a better tomorrow, making progress, etc. This interpretation felt more apt, since the Titan's original Japanese name ("Shingeki no Kyojin") translates closer to "Advancing" than "Attacking." Building on Kruger's words, Attack on Titan episode 79 provides the full picture behind the Attack Titan's name - the Advancing Titan sees events in advance. Ever since the "Attack Titan" name was first uttered, therefore, Attack on Titan has been foreshadowing this hidden future sight ability.

Although Kruger believed the Attack Titan's name came from its relentless march forward, Grisha realizes the future sight ability fuels that drive. Witnessing successors' memories and the horrors/victories yet to come forces the Attack Titan to act where others give up passively. In Eren's case, the mysterious future from Grisha's memories provides his reason to "advance." For Grisha, memories shown by Eren encourage his the Reiss family slaughter.

The true meaning of the "Attack Titan" name also adds a new layer of meaning behind the anime title itself. When Attack on Titan (or Shingeki no Kyojin in Japanese) begins, fans naturally assume the phrase is referencing humanity's war against the Titans advancing from beyond the walls. Given everything we learn in Attack on Titan episode 79, the anime's name can just as readily apply to Eren's Attack Titan, and how it can peer into the future.
