Zero appears in Super Smash Flash as the only unlockable character of the Mega Man universe, and is unlocked by clearing Adventure mode with Mega Man X on normal or harder without continuing. His sprites were ripped from Mega Man X3. Zero is ranked 5th on the tier list. He has a solid projectile in his Z-Buster, excellent range, and good KO moves in Rei Shiki Kitazan, Rei Shiki Kabutowari, and Kuenzan. He's also fairly fast, which gives him a good approach. Like the other sword users, he can also cancel his aerial momentum with Rei Shiki Retsuzan to increase his survivability.
