The name of Zer0 may be a reference to the character in the Megaman X series called Zero. The coloration is very different but both are known for their swordsmanship and both have some kind of light activation on their head. Zer0's helmet projects the number 0 at certain points while Zero has a crystal on his head that lights up under certain circumstances. Both have a dark edge with Zer0 being a brutal assassin always up for a challenge and Zero being developed originally by the evil Dr. Wily. Zero has a determination to meet every challenge and is always concerned about going rogue and being evil.
