Vile is a minor antagonist in the Mega Man Xseries. He used to be a member of the Maverick Hunters prior to the first Mega Man X game and was ranked S-A Class in Sigma's 17th Elite Unit prior to his commander's rebellion against humanity. He appeared in multiple games of the series as a boss character and was playable for the first time in Maverick Hunter X, a remake of the first game for the PlayStation Portable.

Chill Penguin, known in Japan as Icy Penguigo is one of the Mavericks from Mega Man X based on a penguin. He was a Maverick Hunter from the 13th Polar Region Unit. There was strong animosity between him and Flame Mammoth. Possibly as a result, his defeat freezes the lava in the latter's stage, allowing X to walk over it with impunity.

In the OVA, The Day of Σ, he moved to the 17th Elite Unit and was underSigma's command. During this time, he also led a company within the Elite Unit called "Chill Penguin Company," identified by light blue armor-clad humanoid Reploids. When the revolt started, it sounded fun to him, so he joined up to leave his boring post at the South Pole.

In Mega Man Maverick Hunter X, he is voiced by Dean Galloway, the same voice actor of Dr. Wily in Mega Man Powered Up. Also, in this game it is implied that Chill Penguin's involvement in the rebellion was also in part due to his jealousy of X.

In Rockman ×over, Chill Penguin is the boss of the tutorial and one of the four bosses from World 1.

Spark Mandrill, known in Japan as Spark Mandriller is a mandrill-type Maverick from Mega Man X. He was a Maverick Hunter that served in the 17th Elite, which was underSigma's command. When Sigma started his rebellion, he "logically" decided to follow along.

In Rockman ×over, Spark Mandrill is one of the four bosses from World 1.

Armored Armadillo, known in Japan as Armor Armarge is an armadillo-type Maverick in Mega Man X. He was aMaverick Hunter from the 8th Armored Division under Sigma and was a very loyal soldier. When his master rebelled against humankind, he followed suit only to be loyal.

Launch Octopus, known in Japan as Launcher Octopuld is an octopus-type Maverick in Mega Man X. He was a Maverick Hunter from the 6th Marine Unit under Sigma who followed his revolt. In Mega Man X5, he was revealed to be a friend and/or brother toSquid Adler, depending on the translation; his name was also mistranslated as "Octopardo". He appears in Mega Man Maverick Hunter X in the same role as before, with a slightly effeminate personality.

Boomer Kuwanger renamed Boomerang Kuwanger in Mega Man Maverick Hunter X, is a Maverick in Mega Man Xbased on the stag beetle ("kuwagata" in Japanese). He was a Maverick Hunter from the 17th Elite Unit under Sigma, the same unit as his brotherGravity Beetle and X. He has no sense of right and wrong, making decisions based only on logic. When Sigma rebelled, he used deductive reasoning and joined the rebellion. He took control of a tower that would be the symbol of a city, and used it as a fortress. When X reached the top of the tower, Kuwanger saw that X had great potential and thought that he would be fun in a fight.

Sting Chameleon, known in Japan as Sting Chameleao  is a Maverick in Mega Man X based on the chameleon. He was a Maverick Hunter in charge of the 9th Special Forces under Sigma. He's sly and respects only the strong, which may have been his motivation for joining Sigma. He can blend into his surroundings and uses strategy to defeat his enemies by any means necessary; sometimes called a coward for this. Also, when asked by X why Sting Chameleon fell for Sigma's Rebellion, he hints that he, and possibly some other Maverick-turned Maverick Hunters, may have been forced to join due to hostages being involved.

Storm Eagle, known in Japan as Storm Eagleed is a character from the Mega Man X series, a Reploid based on an eagle.

Flame Mammoth, known in Japan as Burnin' Noumander is a Maverick in Mega Man X based on thePalaeoloxodon naumanni. He was a Maverick Hunter from the 4th Overland Unit under Sigma. He had an arrogant and cocky attitude, and was extremely proud of his large size and strength. His tendency to look down on those smaller and weaker than him, put him on bad terms with his subordinates, as well as highlighting the potential cause for the tension withChill Penguin, one of the few higher-ranked members of the Maverick Hunters who refused to join units with him due to their tumultuous relationship.

In Rockman ×over, Flame Mammoth is one of the four bosses from World 1.

Bospider portmanteau of "boss" and "spider"), known as Bosspider in the remake Mega Man Maverick Hunter X, is the giant spider boss at the end of the first part of the final stages in Mega Man X andMega Man Xtreme. It was once used to crush scrap metal before being roped into guarding Sigma Palace.

It releases mini spider robots and creates random paths down its four rails to crush X, so the player must stay on the move. Its method of navigation is a parody of Japanese lot-drawing, or Amidakuji. It has strong defense, but a red core on its abdomen, its weak point, will be exposed when it hits the ground. In Mega Man X, its main weakness is Shotgun Ice (along with Magnet Mine in Mega Man Xtreme), but it is difficult to hit the boss with it (or the Hadouken) in time to hit the core when it appears, as it is only exposed for a short time. When it dies in the remake, Maverick Hunter X, it rolls over onto its back and tucks its legs to its body before exploding (a common misconception of how spiders die in real life. In fact, spiders never roll onto their backs, but stay upright while tucking their legs under their body).

Rangda Bangda is the boss of the secondSigma Palace stage of Mega Man X and its remake Maverick Hunter X. Its design was based on an ancient mural Sigma once saw in Southeast Asia while still working as a Maverick Hunter.[1]

It looks like a face in the background wall with moving eyes, a nose gun, and a mouth serving as a pit of spikes. It can also move its side walls inward to try and force X into the spiked pit. In Mega Man X and its remake, the best weapons to use against it are Chameleon Sting and Rolling Shield.

D-Rex is the boss of the third section of Sigma Palace in Mega Man X. It was supposed to be a large Mechaniloid based on the T-Rex (hence the name), but by the time the fortress was discovered by Zero, only the head was completed, forcing Sigma to convert it into a tank.

Its top can detach from the bottom, hovering in the air, and both try to crush and seriously damage X. When either section collides with a wall, it can daze X and knock him off. Both sections can also charge up massive electron spheres that inflict devastating damage. Its main weakness is theBoomerang Cutter.

Velguarder is Sigma's pet, a wolf-type Reploid[3] orMechaniloid[4] possessing a ferocious mind circuit, whom Sigma uses to hunt down and terminate those who betray him.[3] As Sigma oversaw his production, the two share several common traits.[3] Similar to Sigma, Velguarder is capable of launching a quick triangular attack, leaping back and forth between the wall, the ceiling and the ground. He is also able to fire powerful flames and ice attacks from his mouth.

In Mega Man X and its remake, Mega Man Maverick Hunter X, X must face Velguarder before confronting Sigma himself in Sigma's hideout. Velguarder's weakness in these encounters is Shotgun Ice.

In Mega Man Xtreme 2, Velguarder is the first boss of the final stages, and is weak to X's Ray Claw and Tornado Fang special weapons, and Zero's Risingand Drill Crush techniques.

Sigma formerly referred to as "Commander Sigma", is the main antagonist of the Mega Man X series. He serves as the final boss in all X series games except Mega Man X: Command Mission (where he makes no appearances) and Mega Man X8 (appearing as the final boss if the game is played on easy, and as the penultimate boss if the game is set to normal or hard difficulty, since Lumine is fought on normal or hard).

The first Reploid created by Dr. Cain,[1] Sigma was considered the finest of the Reploids and was the first leader of the Maverick Hunters; peace-keeping Reploids who defend humans against their renegade counterparts. Although he was once honorable, Sigma unexpectedly goes Maverick in the beginning of Mega Man X and rebels against humankind. He defects to the Mavericks and assumes the role of their leader. Under Sigma's command, the Mavericks grow into a legion dedicated to the extermination of the human race. Sigma instigates many of the destructive Maverick Wars, with the Maverick Hunters existing to crush Sigma and his minions.

Although he has been destroyed countless times, Sigma's programming always survives and builds himself a new form, ready to menace the world once again.[2] It is implied that he grows more insidious and vengeful with each transformation, with each successive plan becoming more and more desperate and aggressive. His primary enemies areX, Zero, and more recently, Axl.
