Senescencia

is a technique used by Baraggan Louisenbairn.

Description
As the Espada who represents death by aging, Baraggan can dilate time around him, thereby reducing the speed of any target which comes near him, giving him sufficient time to counter incoming attacks. He used this aspect of the ability in his fight against 2nd Division Captain Suì-Fēng and her lieutenant, Marechiyo Ōmaeda, so they were incapable of landing a hit on him. Additionally, Baraggan can accelerate the age of whatever he touches, causing the appropriate damage which comes with aging. Baraggan aged Suì-Fēng's left arm to the point where its bones became brittle enough to eventually break. Baraggan was able to move behind Suì-Fēng and lightly tap her on the shoulder, with Suì-Fēng only being able to express confusion at what just transpired.

Upon the release of his Resurrección, Baraggan's Senescencia increases in strength, allowing him to age and deteriorate every object around him; even the very building he walks upon begins deteriorating from his mere presence. Because of this, he is protected from most close-range and melee attacks, for everything which comes within a specific range of him rapidly ages and disintegrates before actually making contact. Baraggan deteriorated numerous rocks thrown at him by Ōmaeda's Shikai as they made contact with his field. He used the ability on Suì-Fēng's Bankai to make it explode far away from him, allowing him to escape the blast relatively undamaged.
