Sigma/Maverick Hunter X

"Listen well, X. There are times when we Maverick Hunters cannot afford to hesitate in pulling the trigger. We must become both sword and shield to those who cannot protect themselves - that is our sworn duty. Never forget that!"

- Commander Sigma before his rebellion

"It's not over yet, X! The battle! The angst! The destruction! I will make you understand the true potential of Reploids!"

- Sigma as a Maverick

Sigma is a character from Mega Man Maverick Hunter X, a Reploid that was originally the leader of the Maverick Hunters, but betrayed them and Humaninty, becoming the leader of a Maverick army.

The Day of Σ
Sigma appears in a short unlockable OVA in the game Mega Man Maverick Hunter X for the PSP entitled "The Day of Σ". It shows the Maverick Hunters prior to the events of the game under Sigma's command, before he ultimately revolts, declaring total war on humanity. It should be noted that the events in this OVA coincide more with the canon of Mega Man Maverick Hunter X than with that of the original game.

Trivia

 * There was a slight change in music prior to confronting Sigma upon defeating Velguarder. In the original game, Sigma, when appearing to confront X personally, had the pre-Fortress battle music playing. In the remake, an entirely new tune was used for his interactions with X during this time.
 * On a similar note, in the original game, he warped out just before the Velgaurder boss fight, and only returned after Velgaurder was destroyed. In the remake, he was present the entire time and saw the entire fight.
 * A similar change of music was also present in regards to the leadup to the Wolf Sigma boss fight, partly due to the inclusion of a voiced cutscene before the battle. Originally, the second phase theme started playing as Sigma's head merged with the mech. In the remake, it played after the boss health bar filled up, with a lower mix of the Day of Sigma theme playing during the cutscene leading up to the boss battle instead.
