The battle is one-sided, with the Masked Man knocking all of the other party members unconscious before the battle even begins and continuing to knock them out with a sure-hit KO thunder attack if they're ever revived, while Lucas refuses to attack Claus, with the newfound knowledge that his brother is still alive. In the Final area, after Porky has been confronted and Flint tells the party the truth of the Masked Man's identity, he is fought as the game's final boss. His true identity is revealed at the end of Chapter 8 it is also revealed that the Pigmask army had found him since the end of Chapter 1 and turned him into a human Chimera after learning of his psychic abilities.

By the end of the chapter both have pulled an equal amount of needles, meaning the Dark Dragon will inheret the heart of whoever pulls the last needle, located underneath New Pork City. When encountered throughout the chapter, a strange tension fills the area whenever his eyes meet with Lucas', although both stay speechless. He is encountered several times during Chapter 7, wherein he pulls the Osohe Castle, Snowcap Mountain and Tanetane Island needles for the Pigmask Army, and is confronted as the chapter's end boss in front of Chupichupyoi Temple. Among his other abilities, he can fire powerful bolts of lightning that can cause instant knock-outs - provided that the target isn't wearing a Franklin Badge - and is equipped with a personal jet pack to easily navigate the Nowhere Islands with. He and Lucas race around the Nowhere Islands to pull the Needles, following Porky's plan to end the world out of boredom, using the Masked Man as a vessel to pull the needles. He has the ability to use PK Love, and because of this, he is the only person besides Lucas who can pull the Seven Needles. He is the commander of the Pigmask Army, and is mainly controlled by Porky. The Masked Man is first seen briefly at the end of Chapter 5, and is introduced in Chapter 7, although he is alluded to several times times beforehand, particularly when Lucas is confused for him for the majority of Chapter 5.
