Global Alliance

Also called the Allied Nations, the coalition draws its strength from the Global Allied Fleet, an armada pooling the naval power of every participating country. Each warship carries the most advanced artillery in existence, weapons chosen specifically to meet the Wall Titans if the Rumbling ever began. The union's stated aims are stopping Eren Yeager, destroying the island's Eldians, and restoring the world as it was.

The coalition's seed is planted at a festival in Liberio, where Willy Tybur stages a theatrical retelling of Eldian history before an audience of ambassadors and dignitaries. He warns them that the Founding Titan no longer rests with the peace-minded royal line but with Eren Yeager, reviving the specter of a world-flattening Rumbling, and pleads for every nation to stand with Marley. Eren answers by transforming mid-speech, killing Tybur and many of the assembled diplomats. That massacre accomplishes what Tybur's words alone might not have: the world unites against Paradis.

In the raid's aftermath, General Theo Magath tells the surviving Warriors the allied assault will be ready within six months; Reiner Braun, unwilling to wait, pushes for an immediate surprise strike instead. Zeke Yeager, aware of what the coalition means for his own designs, escapes Levi Ackerman's watch to reach Eren. When the brothers link and the Wall Titans march, the Allied Fleet forms a blockade off the mainland's northeast coast. Its guns accomplish nothing; the Titans capsize and shatter the ships, then stride onto the continent. Yelena later admits she had pointed Eren toward Karifa, Marley's northern port, a year earlier as the likely mustering point for such a fleet and a fitting target for a partial Rumbling.

Three years after the Rumbling ended, the surviving nations chose their ambassadors to Paradis from the very people who killed Eren Yeager: the Warrior Unit veterans and Survey Corps turncoats Armin Arlert, Reiner Braun, Annie Leonhart, Pieck Finger, Jean Kirstein, and Connie Springer, tasked with opening peace negotiations with the island.
