### Summary
The devastating war at Marineford lays bare the profound bond between brothers, revealing why the intelligent and composed Ace has always been so protective of his younger sibling. Beneath his usual simple-minded optimism, Luffy's raw emotional vulnerability—a "crybaby" nature forged in their shared childhood under their foster mother, Dadan—shines through in the face of losing his family. This deep-seated loyalty is the very heart of the conflict, a stark contrast to those who, like Doflamingo, would destroy family for power.
