"I never cared about justice, and I don't recall ever calling myself a hero. I have always only fought for the people I believe in. I won't hesitate... if an enemy appears in front of me, I will destroy it!"
Zero is the main protagonist of the Mega Man Zero series. As a legendary freedom fighter in the Zero series, he's a die hard warrior who doesn't hesitate to take action. However, behind his cold and emotionless attitude lies a wounded soul.
Zero was created by Dr. Albert Wily during the early 21st century. Wily claimed that he was his "greatest masterpiece". Learning from his past mistakes, including the accidental creation of Bassnium, and his construction of Bass and King, Wily constructed a new robot, far more advanced than anything he had ever built before with a power level far superior than Bass or even Megaman. Wily took the time to complete Zero, originally planning to use him against both Megaman, and his insolent rebellious Bass. However, this never happened, and he was never utilized during the Wily Wars. Zero was routinely activated in a semi-conscious state during his construction, and Wily conversed with him, mirroring what Light himself did with X.
