Harden

Harden is an option in Completing the Mission during the "Free Man" pathway.

Henry can use this when fighting Right Hand Man Reborn in the cafeteria of the Toppat Orbital Station. When chosen, Henry turns his entire body to stone or rock. However, the Right Hand Man is strong enough to still shatter his head with a single punch, killing Henry. This results in a fail.

Fail Message
It's not very effective...

Trivia

 * The option is based on the Harden move from Pokémon. This is further backed up by the fail screen stating "It's not very effective"; a message commonly displayed in the Pokémon games if a move has little to no effect. How the Right Hand Man Reborn can shatter Henry's head with his metal fist may also be a nod to how Steel-type moves are more effective on Rock-type Pokémon.
