Shadow Man (DWN-024) is a mysterious ninja-themed robot that appears as one of the eight Robot Masters in Mega Man 3. His origins are unknown, but he was discovered by Dr. Albert Wily inactive in a junk yard, and the doctor reactivated him, modified and reprogrammed him into a loyal warrior and spy. He possesses many ninja techniques and is a master of stealth.
- Martial Arts - Shadow Man is an expert at hand-to-hand combat. One of his favoured attacks is a slide attack to knock opponents off their feet.
- Swordplay - While not apparent in Mega Man 3, Shadow Man has wielded a katana in the Megaman Megamix manga series.
- Shadow Blade - A large throwing star. Its edges are coated in a lethal substance that can spread through and corrode robot systems like a poison. Mega Man can copy this ability.
- Stealth Techniques - True to his ninja design, Shadow Man can vanish in a puff of smoke and reappear from the darkness to strike at unwary foes. Another interesting ability he possesses is shadow-melding - he can literally use shadows to move around, diving into one shadow and reappearing from another several meters away. He has displayed this power in the Megamix manga.
Like most of the Robot Masters in Mega Man 3, Shadow Man is vulnerable to his own weapon. Other than the Shadow Blade, he cannot stand against Top Man's Top Spin attack, which lets the user move and strike so fast that Shadow Man cannot counter or block.
