Senescencia

is a technique used by Baraggan Louisenbairn.

Description
As the Espada who represents "aging", Baraggan is able to dilate time around him, thereby reducing the speed of any target that comes near him, giving him sufficient time to counter incoming attacks. He used this aspect of the ability in his fight against Suì-Fēng and Ōmaeda so that they were incapable of landing a hit on him. The ability also allows him to accelerate the age of whatever he touches, causing the appropriate damage that comes with aging. This portion of his ability was used to age Suì-Fēng's left arm to the point that its bones became so brittle that they eventually broke. His proficiency in this ability is so great that he was able to get next to Suì-Fēng and lightly tap her on the shoulder, while the latter could only react with confusion at what just transpired.

Upon his Resurrección, Baraggan's Senescencia increases in strength, to the point that he can 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.
