Heritage for the Future ★ Proud Lineage Joseph
Joseph also has his Part 2 incarnation, named Proud Lineage Joseph (誇り高き血統ジョセフ) or simply "JoJo" in the English localization, as an unlockable secret character. In this form, Joseph's main attack is his Clacker Volleys, where he uses it as a pair of nunchucks and boomerangs. His first special move is similar to his Part 3 counterpart though instead of whispering Lisa Lisa's name he screams Caesar's.
His other special move uses the Red Stone of Aja; by charging it with his Ripple the stone shoots a powerful Ripple beam (similar to what Kars and Lisa Lisa did it during the events of Part 2) that will set opponents on fire. Some characters can duck under the beam, while characters like DIO and Joseph himself will still be hit while crouching.
"JoJo" can also use a crossbow to shoot an iron pellet across the screen to hit the enemy from the other side as well as a bottle cap from a coke bottle as a projectile, all of which are attacks that originated from the manga.
"JoJo" can also be 'activated' if Old Joseph is hit with Alessi's Stand, though temporarily, and missing a majority of his moveset other than kicks and punches. If "JoJo" is hit by Alessi, he will appear as his 13-year old self from the flashback with Speedwagon, and uses a weaker Ripple attack while flipping through a comic book.
His Story Mode in JoJo's Venture has him simply face off enemies until reaching Shadow Dio, with no storyline involved. In Heritage for the Future, it becomes a what-if sidestory if Joseph encounters Alessi, turning into his Battle Tendency incarnation, and fighting some allies in the process, before facing off Alessi himself and reverting to his normal form, albeit with a little regret of becoming old again.
Joseph turns into an even younger Joseph holding a Superman comic if hit again by Alessi.
