Anyway, Sigma is a badass, he along with Ganon are the villains who just refuse to quit or die.
I didn't whine at you for making the Tifa respect thread.
Anyway, here is some more in-depth info on Sigma.
Pre Megaman X
As the former leader of the Maverick Hunters, Sigma was originally the most advanced Reploid of his time. Dr. Cain implanted the latest circuitry designs into Sigma, which were theoretically supposed to prevent him from going Maverick. He was placed in charge of the 17th Elite Unit of the Maverick Hunters, and led them to victory multiple times.
One day, the Maverick Hunters receives reports of an overwhelmingly powerful "Red Maverick" that has destroyed an entire squadron of Hunters (the Gamma unit). While investigating, Sigma, along with his unit, tracked it down to an abandoned laboratory. It is here that Sigma encountered Zero, the last product of Dr. Wily; Zero carried with him the malicious "Zero Virus" which powered up his abilities and turned him into a "blood-thirsty god of destruction." Sigma was beaten badly by the maddened Zero, but managed to smash the energy crystal in Zero's helmet, which transferred the Virus directly into Sigma. Zero lost consciousness, and Sigma limped away from the battle, ordering his men to take the body of Zero back for study.
Megaman X
Sigma's advanced circuitry seems to do its job, as he seemingly remains stable for months after the lab incident. He gradually succumbs to the virus inside of him and grows more volatile. Without warning, he leads a mass revolt among the Reploids, declaring total war on humans. Many Maverick Hunters follow Sigma out of loyalty, leaving Zero in charge of the organization. By this time, he has reformed and become a powerful Maverick Hunter. X, the last creation of Dr. Light and the base model for every Reploid, decides to join Zero as thanks for saving his life. X and Zero battle through the Maverick regime, and it is X who finally destroys Sigma. But though his physical body is scrapped, Sigma's "soul" (the Virus) survives. After the end credits roll, Sigma's face appears on a blue monitor and warns X that he will be back.
Megaman X2
Just as he said he would, Sigma returns and reassumes leadership of his Maverick forces. He gains a new robot body with the help of the X-Hunters, a trio of vengeful Mavericks who worship him, and becomes Neo Sigma. He also oversees the "Unification" plot, capturing and re-assembling of the remains of Zero, who he reprograms to kill X in the final battle of the game. Sigma attacks in a new form, armed with clawed hands, but X thwarts his plans and destroys him again. Zero is then restored to his rightful place in the Maverick Hunters, and given his own command as leader of Special 0 Unit.
Megaman X3
Sigma resumes his threat when he infects the Reploid scientist Dr. Doppler, who has developed a revolutionary new anti-virus to repel Sigma's influence. Sigma uses him to stage the revolts in Doppler Town, a utopian city established on the principles of peace. Once Doppler is unmasked as a pawn, Sigma emerges in a heavily-armored form ("Kaiser Sigma"
. After he is defeated for the third time, Sigma's "Soul" appears in the form of a wire-frame head and threatens to possess X's body to replace its own. After chasing X through the flaming wreckage of the base, Sigma finally corners him. If X fails to kill Vile and faces him again in Doppler's Base, Zero appears and utilizes the anti-Virus created by Doppler to erase Sigma for the time being. If X kills Vile and Zero gives X the Z-Saber, Doppler uses the anti-Virus and sacrifices himself to destroy Sigma's programming.
Megaman X4
Sigma was thought to be suppressed forever after Zero distributed the anti-virus created by Doppler, but he still manages to return. In the introduction of the game, Sigma acts as a double-agent between the Mavericks and Repliforce, a benevolent squadron of Reploids who assist the Maverick Hunters. Sigma's true motive is to conspire against Repliforce and turn it into a rogue enemy. He stages the bombing of the airborne metropolis Sky Lagoon, which plummets to the ground in the opening of the game. Sigma also hacks into the Maverick Hunters' Mother Computer and infects it with Maverick data, causing their bases to be targeted by Repliforce missiles.
With in-fighting between the Hunters and Repliforce threatening to destroy them both, Sigma increases his influence over the paranoid General of Repliforce. The General, an outspoken advocate of Reploid independence, loses all faith in peace and prepares a satellite laser attack on all humans; fortunately, X storms the space weapon and stops the General before he can turn its sights on Earth. In the end, Sigma is revealed as the true mastermind and battles X himself, armed with a new body and a scythe. Despite his defeat at X's hands, he succeeds in part by destroying Repliforce.
