|Mega Man using Hard Knuckle.|
Hard Knuckle (ハードナックル Hādo Nakkuru?) is Hard Man's Special Weapon. When utilized, there is a short delay before the knuckle starts moving forward. It is somewhat slow, but has great strength. Mega Man can slightly guide the knuckle up or down once it is moving. It does moderate damage to Spark Man and Shadow Man. Hard Knuckle can also be used to break through Destructible Blocks in Mega Man 3 and Mega Man: The Wily Wars.

Mega Man uses Hard Knuckle in episode 25 of the Mega Man animated series. After defeating Hard Man by blowing him up from the inside with a Mega Buster shot, Mega Man copies the Hard Knuckle from him, utilising it to knock Proto Man off a rock he was standing on to fire at the heroes.
It also appears in episode 32 of Captain N: The Game Master, where he uses the Hard Knuckle to defeat Top Man.
The Hard Knuckle is used by Mega Man in the upcoming fighting game, Super Smash Bros. for Nintendo 3DS / Wii U, as his Down Air attack. Here, it involves Mega Man firing the Hard Knuckle directly below him to function like a projectile Meteor Smash, knocking foes in midair straight down upon contact.
