To put Napalm Man into perspective; when napalm ignites, it can reach temperatures of 2,760 degrees Celsius (5,000 degrees Fahrenheit), according to “science.howstuffworks.com”! Napalm can stick to targets easily too, due to it its gel-like consistency, and is usually used in warfare. What all of this means is that Napalm alone can melt steel when set on fire, but a mobile weapon like Napalm Man can do far worse. Napalm Man doesn't really have any friends, even among the baddies he's allied with; they don't want to get near this guy and with good reason!

Created by Wily, Napalm Man is programmed to be a weapons enthusiast, which means he has a pretty good idea what he's up against! He shoots all kinds of missiles, grenades, napalm, and is a danger to everyone around him, including himself. He's popular among Mega Man fans and has been in Mega Man 4, Mega Man (game gear), Mega Man: The Power Battle, Mega Man 2: The Power Fighters, and Mega Man: Battle & Chase. In “Mega Man: Battle & Chase”, if the player wins the game using Napalm Man, he builds a weapons museum, gets angry at someone for not liking it, and blows up his own museum. On a side note, Napalm Man's weakness is Pharaoh Man's “Pharaoh Shot” in Mega Man 4, and the “Crystal Eye” in Mega Man 5.

Created by Dr. Cossack; “Pharaoh Man” was made to resemble the pharaohs of ancient Egypt. Originally, “Pharaoh Man” was designed to help in archaeology, uncovering treasures from pyramids; which didn't last long after Wily figured out what Cossack could make. Forcing Cossack to do his dirty work, Wily ordered him to modify his bot to destroy Mega Man. Pharaoh Man was modified with solar-powered weapons, a shield, the ability to levitate (see “The Power Fighters”), and can summon the robot version of the “Walking Dead” (see “The Power Fighters”).

Considering one of the easiest ways to defeat Pharaoh Man is to freeze him in place, says a lot about how tough this guy is; he bounces around like a coffee addict with a Pogo Stick! Jumping aside, he can use the power of the sun itself as a weapon, which is pretty overpowered all by itself! He also has command of a robot army known as the “Mummira”; who like to toss heads at Mega Man. Many years have passed since Mega Man 4, but this memorable character was featured in several Mega Man games like: “Mega Man: Soccer”, “Rockman Strategy”, and “Mega Man 2: The Power Fighters”.

Who can forget that iconic Proto Man whistle, which foreshadows the arrival of Proto Man? No one, that's who! Proto Man was designed by Dr. Light. He was to be the first robot capable of thought, and a prototype/template for all other robots. One day, it was discovered he had robot cancer in his energy core or something; unwilling to lose his current personality, Proto Man refused repairs from Dr. Light and ran away. Dr. Wily found Proto Man and gave him a new energy core, which made Proto Man indebted to the evil Dr. Wily. When Dr. Light created Mega Man, Wily sent his brother (Proto Man) to destroy him. Eventually, Proto Man saves Mega Man instead, proving that Proto Man really is good at heart.

Proto Man wields an indestructible shield that can be used to deflect almost any attack. Like Mega Man, he uses an arm cannon. However, he can fire at a faster rate than Mega Man, and can use short-ranged attacks. One of Proto Man's lesser known abilities is “Variable Weapon System”, allowing him to copy weapons from other robots like Mega Man. Proto Man also uses “Big Bang Strike”, which is an energy blast of massive power; used to destroy near to indestructible objects (like King's shield). Being Mega Man's brother also means that Proto Man doesn't wish to kill Mega Man, and disobeys Dr. Wily quite a bit. He has been featured in Mega Man 3 – 10, Mega Man & Bass, Mega Man's Soccer, and Mega Man: Battle & Chase.

Destroying an asteroid takes an astronomical amount of force (pun intended), and Slash Man's claws are said to be capable of such a feat; though Wily never said how long it would take Slash Man to destroy said asteroid. Slash Man's claws can rip just about anything to shreds, and he can be a very annoying boss to fight in Mega Man 7! One of the best strategies to beat him include freezing him in place, much like Pharaoh Man! He also likes to climb things and pounce on you from the ceiling trying to slash you, like a robot version of Wolverine. Slash Man can also drop egg-like bombs from the ceiling, which can disable all of Mega Man's abilities temporarily.

“Slash Man” was originally said to be a logging robot for construction purposes, but was later modified by Wily to slash many other things. He was given control of a robot army in the form of robot dinosaurs; some of the deadliest robots ever conceived! Luckily for Mega Man, the robots in his stage really aren't too bright, and are easily defeated. Good old Slash Man doesn't like it when he's too hot, or too cold, and has 2 weaknesses you can exploit as a result.

“Yellow Devil” is another one of Dr. Wily's creations, and a recurring character in the Mega Man universe. He is usually depicted as a hulking, yellow blob-like beast with one eye, and is indestructible when his eye isn't out in the open. The Yellow Devil has been known to break apart into deadly projectiles, and reform at the other side of an enemy; sort of like the T-1000 from Terminator 2. Yellow Devil's range for his reforming attack seems to be limited, however, so he fights best in enclosed areas.

While the Yellow Devil can cause mega-issues for Mega Man, he has an easily decoded pattern of repetition, allowing Mega Man to easily dodge most of his attacks (most of the time). The Yellow Devil is one of the most iconic bosses in Mega Man history, and is annoying as hell to fight! Mega Man beats him by dodging his reformation projectiles, and shooting him in the eye when it becomes vulnerable.

Tron is a genius level pirate, who can build mechs, and has a robot following (servbots); they look like Lego versions of Gru's minions from “Despicable Me”. She is adorable, and builds adorable robots of death! Despite being a pirate, she does seem to have a soft spot for Mega Man when he saves her in “Legends”, and develops an unhealthy obsession for him. Tron is weak physically, but put her in one of her mechs and she is a force to be reckoned with! Tron Bonne maintains all of the machines in the Bonne family, including their airship the “Gesellschaft”.

It's safe to say she is the world’s most powerful 14-year-old girl in the Mega Man universe! Her mechs are like an extension of her body. Tron Bonne has been in many games; including her own stand-alone game “The Misadventures of Tron Bonne”, and even the “Marvel vs Capcom” franchise. In Marvel vs Capcom 2 and 3, players who are good with her tend to win almost every damn time; she is an annoying character to fight! In “Legends” all you must do is shoot the weak spots on her super-sized mech, thankfully. Clearly, looks can certainly be deceiving, and so can age!

Bass was designed by Wily to surpass Mega Man's design after tireless research, and he even had his own robot dog Treble (Gospel in Japan); to counter Mega Man's Rush. Bass was first encountered in Mega Man 7, and made appearances in a bunch of other Mega Man games thereafter; most notably “Mega Man & Bass”! Being Wily's creation Bass is, of course, programmed to destroy Mega Man. Unfortunately, Dr. Wily sort of outdid himself, and Bass was a bit rebellious as a result. Wily ended up getting his ass kicked by Bass many times. Bass was especially angry after contracting the “roboenza” virus in Wily's castle in Mega Man 10.

Bass can merge with his robot dog, transforming into “Super Bass”; a powerful flying menace with an array of annoying attacks. Despite being the rival of Mega Man, Bass sometimes works with him to accomplish goals; like throwing “King” (a powerful evil robot) out of Wily's castle, and even take on Wily himself. Bass is always out to prove he's the best at what he does, and is always challenging Mega Man in many ways as a result!

A violent war breaks out between robots and humans thanks to Wily's “Maverick Virus” (and Sigma) making robots go “maverick”; the robot version of insane. After years of hibernation, thanks to Dr. Light, Mega Man X is awakened and later takes on the maverick robots; greatly surpassing the original Mega Man in every way. X lives to see the world plunged into chaos, and taught that he must help humans and reploids (the robots) from being overrun by maverick bots. Most people will remember the secret in Mega Man X; the ability to use the “Hadouken” from Street Fighter, which would instantly kill any boss in the game! Mega Man X is strong, and has “unlimited potential”, according to his colleagues.

All the modern day reploids were modeled after “X” thanks to Dr. Cain's genius; which makes “X” all of their daddies (with the exception of a few). Originally, the reploids were designed to co-exist and get along with humankind before the virus broke out; peace lasted for a long time! Luckily, the world has “X” around to eliminate the present maverick threat! Currently, “X” is about to take on his nemesis (Sigma) again in “Marvel vs Capcom: Infinite”.

Zero was the last-ditch effort made by Dr. Wily before his death; Wily wanted to leave his mark on the world, and Zero was put into hibernation much like X was by Dr. Light! Sigma finds Zero's capsule, wakes him up, witnesses Zero destroy everything in the room, and is severely damaged by Zero! After the short scuffle, Zero calms down, learns about the world in the same way X did, and joins the maverick hunters (take that Wily). Unfortunately for the entire population of reploids (and humans), Zero's capsule released the “Maverick Virus” upon his awakening, infecting Sigma.

Zero is one of X's best friends; uses a short-range saber; long range buster, and is generally a total bad-ass. Zero is often shown to be far stronger than X, and saves his life multiple times. Zero has been in many games, and will be in the latest “Marvel vs Capcom” game along with X and Sigma. Zero has destroyed countless baddies, and is capable of multiple abilities. Zero is seriously powerful, and Dr. Wily's greatest creation.

Sigma is the most powerful reploid made by Dr. Cain, and was made to serve as leader of the “Maverick Hunters”. He was designed to keep the peace between man and machine; but is infected with a virus that was in Zero's capsule. Slowly, Sigma becomes insane, goes maverick, and tries to kill everything in his way. Sigma wants to crush humanity, and all things flesh; he then launches a nuclear attack on the city he was supposed to protect. Sigma is also capable of infecting any machine with his virus and bend them to his will, creating many issues for the good guys.

Sigma can transfer to just about any machine, and is damn near indestructible as a result; he's more like software than hardware! Sigma is so powerful, he's even infected X and Zero at certain points in the Mega Man X games; he makes them both go maverick at certain points! Sigma is like a head that keeps growing back after you cut it off; he's been physically destroyed several times. Sigma merges with Ultron in “Marvel vs Capcom: Infinite”, and is one of the main antagonists in that game.
