El Martillo, translated as 'The Hammer' or 'Fey Hammer,' is a Hollow technique belonging to Ayon. The beast enlarges its right arm to more than double the usual thickness, adding enough mass to drive the limb's crushing, destructive power sharply upward.
Ayon's right arm balloons to well over twice its normal girth, a change plainly visible in the sheer bulk the limb suddenly gains.
The swelling multiplies the arm's mass, and with it the raw destructive force behind a blow, turning the limb into a battering weapon.

Five Bleach female characters, ranked and settled. Yoruichi sits at number five, the spot nobody expects, and our number one is an Arrancar with a soft heart....

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....
