Background

Dr. Mikhail Sergeyevich Cossack is a character from the original Mega Man series. He made his debut in Mega Man 4, initially appearing as the main "antagonist." However, it was later revealed that he was being manipulated, and he ultimately became a trusted ally of Mega Man. Among his contributions, he created the robotic bird Beat as a gift to aid Mega Man in his battles against evil forces.

Dr. Cossack is a highly skilled Russian robotics engineer and inventor. He graduated from the esteemed Ural Technical University, where he honed his expertise in advanced robotics. Throughout his career, he earned widespread recognition for his groundbreaking work, receiving numerous prestigious honors such as the Brzezinski Science Award and the Scientific Achievement Award. These accolades highlight his brilliance and dedication to his craft, solidifying his place as one of the most accomplished minds in robotics.

Dr. Cossack resides in Russia with his daughter, Kalinka Cossack, whom he cares for deeply. His bond with Kalinka is a defining aspect of his character, and his love for her has driven many of his decisions, both good and bad. In his personal time, Dr. Cossack enjoys watching ballet, a hobby that showcases his appreciation for artistic expression and creativity.

Mega Man 4 Dr. Cossack makes his debut in the Mega Man series as the apparent new antagonist after Dr. Wily's repeated defeats. He sends a message to Dr. Light, declaring his intention to prove his genius to the world by creating eight powerful Robot Masters to take over the planet. These Robot Masters include Bright Man, Toad Man, Drill Man, Pharaoh Man, Ring Man, Dust Man, Dive Man, and Skull Man. Each of these robots showcases advanced designs and unique abilities, presenting a significant challenge to Mega Man. Mega Man sets out on his mission to stop Dr. Cossack’s supposed world domination plans, traversing various environments to confront and defeat the eight Robot Masters. After claiming victory over each, he makes his way to Dr. Cossack's Citadel, an imposing fortress filled with traps and powerful defenses. The final confrontation occurs in the Cossack Catcher, a powerful mechanical device piloted by Dr. Cossack. Just as Mega Man is about to deliver the final blow, Proto Man intervenes. He arrives with Kalinka, Dr. Cossack's young daughter, in tow and reveals the truth: Dr. Wily is the real mastermind behind the chaos. Dr. Wily had kidnapped Kalinka and used her as leverage to force Dr. Cossack into his schemes. Freed from Wily’s control, Dr. Cossack expresses remorse for his actions and becomes an ally of Mega Man and Dr. Light moving forward. Mega Man 5 Following the events of Mega Man 4, Dr. Cossack demonstrates his genius once more by designing a new ally for Mega Man, a robotic bird named Beat. Created to assist Mega Man in his efforts to protect the world, Beat becomes a valuable asset, capable of homing in on enemies and delivering precise attacks. While Dr. Cossack does not make a physical appearance in the game, his contributions are acknowledged in the game’s manual. In addition to providing Beat, Dr. Cossack informs Mega Man of Dr. Light's capture and enhances the functionality of the Mega Buster’s charge shot, improving its firepower for the battles ahead. Interestingly, in the Rockman Complete Works version of Mega Man 5, as well as its port in the Mega Man Anniversary Collection, Dr. Cossack plays a more active role. In Navi Mode, he serves as the main guide, offering tips and advice to Mega Man throughout his mission. Mega Man 11 Although Dr. Cossack does not appear directly in Mega Man 11, his influence is still felt. He is mentioned in the game’s lore as the manufacturer of Tundra Man, one of the eight Robot Masters Mega Man must face. Tundra Man’s design reflects Cossack’s trademark craftsmanship, showcasing advanced mobility and cold-based abilities that challenge even the most skilled players. Wily & Right's RockBoard: That's Paradise Dr. Cossack is one of the playable characters in the board game-style spinoff Wily & Right's RockBoard: That's Paradise. In this game, his objective is to build a new laboratory to further his experiments. Players controlling Dr. Cossack must strategically acquire resources and properties to achieve their goal, competing against other characters such as Dr. Wily and Dr. Light.

However, Via says The Player's story isn't over and RiCO repeats this and says that there will be future program errors in the Deep Log for them to correct and it would be insecure for her alone to manage it alone. Therefore to solve this problem that can happen in the future, RiCO will summon The Player in order to correct any irregular data in the Deep Log as she did in the start of the game).

Inside the Mother Computer, X defeats Vile's data form along with the data forms of a bunch of mavericks he has previously defeated. However, despite defeating their data form, their data is still are able to come back for the rematches at the end of the game along with Vile being back in the hard mode's post game story. Despite destroying Vile's data twice, he was still able to come back and better than ever in Mega Man X8. In Mega Man ZX, Omega's soul data along with flashes of the past battle in Zero 3 are trapped in area O and even after defeat, he can come back without limit even after obtaining Model OX which contains his soul data. With data further being explored through here), Resurrection (Repeated Resurrection, Resurrection of the Deceased; Robots that are fought and defeated are able to be brought back as long as they still have their data, with this also extending to reploids being able to come back for rematches. With data further being explored through here), Non-Standard Interaction (Conceptual Interaction & Abstract Interaction; Can directly interact with, harm, and destroy a robots data, which all robots "true existences" rely on their data, thus as long as their data is stored they can be remade or come back if their data is specifically "SAVED". All data resides in the deep log of each game's data and information of the Mega Man Franchise and many other Capcom franchises, with it being stated that data makes up the characters' personality, memories are data pieces that can be used to materialize hunter programs and also have the feelings of the characters, their data is even what determines their own canonicity in reality, with all characters being considered data alongside all universes being made of data. With data further being explored through here).

Resistance to Mind Manipulation and Soul Manipulation (As a Mechaniloid, has even less emotions and AI then a Robot Master where despite how active Robot Masters are they do not actually possess the feeling to think, feel, and make decisions of their own as this level of technology wasn't realized until the reploids of the X era. Along with Reploids having something closer to a human soul then any robot Robot Master has. Robot Masters have a "consciousness" though it is different from the standard humans consciousness as it's at the level of a "cognitive circuit" embedded inside each one of them), Light Manipulation & Paralysis Inducement (Has a complete immunity to flash stopper), Water Manipulation & Acid Manipulation (Has a complete immunity to rain flush), Forcefield Creation (Has a complete immunity to skull barrier)

Superhuman Physical Characteristics, Large Size (Supersized; Is this large compared to Mega Man), Energy Projection (Can shoot out energy projectiles).

• Tundra Man: Tundra Man is a Robot Master who appears in Mega Man 11. He was originally created by Dr. Cossack as a surveillance robot designed to monitor environment changes in some of Earth's coldest regions. He led a lonely life, though, and after watching an ice skating championship on TV, he was inspired to become a professional figure skater. While under maintenance in Dr. Light's laboratory, he was stolen and outfitted with a Speed Gear by Dr. Wily, along with some other modifications, so he could be better suited for combat, after which he took over a museum. His Special Weapon, Tundra Storm, allows Mega Man to generate a column of icy cold air that can destroy enemies directly above and below him.

• Beat: Beat is a bird-type combat support robot from the original Mega Man series built by Dr. Cossack for Mega Man to help him protect the world. He serves a support role by either attacking enemies or protecting Mega Man, depending on the game. Beat made his debut appearance in Mega Man 5, and every mainstream game since has featured him as well as some spinoff games.

Notable Techniques

• Flash Stopper: Flash Stopper is Bright Man's Special Weapon. This is not to be mistaken as Flash Man's power, Time Stopper. Unlike Time Stopper, the Flash Stopper emits an intense light that activates a safety device in the camera eyes of robots, blinding them for a short period, which makes them unable to move and open for attacks. However, when used in the games it appears to freeze time, being able to stop projectiles and enemies without eyes such as Super Ball Machine Jr. and Pakatto 24. Flash Stopper does no damage to enemies directly, but it has a bonus effect: it can allow one to attack shielded enemies, like Shield Attacker and Skeleton Joe, without them being able to block the shots.

• Dive Missile: Dive Missile is Dive Man's Special Weapon. It fires amphibious homing missiles that can lock onto nearby targets, chasing them down before striking. It was originally used to catch big fish before being remodeled for combat.

• Drill Bomb: Drill Bomb is Drill Man's special weapon. It can pierce barriers. Also, Drill Man can set the explosion off early when pressing the attack button after a drill is fired. Drill Bomb can also destroy Garyobies.

Dust Crusher: Dust Crusher, also known as Dust Crasher in Mega Man: The Power Battle, is Dust Man's Special Weapon. It takes the form of a bomb encased in a ball of scrap metal, that explodes and splits into four pieces of shrapnel (diagonally) when it hits something solid.

• Levitation: Either creates a green aura around him while levitating or creates a forcefield around him as he flies around freely.
• Summoning: Summons Astro Zombiegs that help him, they come from the sky in coffins.
• Pharaoh Shot: Pharaoh Shot is Pharaoh Man's Special Weapon from Mega Man 4. It shoots a small sphere of charged solar energy straightforward or diagonally. This is the only weapon besides the Mega Buster that can be charged in Mega Man 4 and Mega Man IV. It quickly charges solar energy in small amounts, eventually accumulating a large amount of energy that can be release as a destructive energy sphere.
• Pharaoh Wave: Pharaoh Wave replaces Pharaoh Shot as the weapon in Mega Man 2: The Power Fighters. When used by Pharaoh Man, it releases two waves, one forward and one backwards. Also, when Pharaoh Man's giant eye is hit, he counters by releasing one wave from the eye. Pharaoh Wave is Gemini Man's weakness, and can hit the two Gemini Men at the same time.

• Ring Boomerang: Ring Boomerang is Ring Man's Special Weapon. It has a somewhat limited range and, as its name implies, boomerangs back, but it can do multiple hits if aimed correctly. It's Dust Man's weakness, but Dust Man is immune to the Ring Boomerang when he has his vacuum on. It is also the weakness of Mothraya, Tako Trash, and the first form of Wily Machine 4. The Ring Boomerang can also pierce some shielded enemies, like Shield Attacker and Skull Man's Skull Barrier. In Mega Man IV, the Ring Boomerang can take items and pull them to Mega Man. Ring Boomerang can also destroy Garyobies.

Skull Barrier: Skull Barrier is Skull Man's Special Weapon. It creates a skull-shaped energy shield that rotates around the user, protecting him from attacks. In Mega Man 4, Skull Barrier automatically shuts off when it takes a hit, but it can stand against a maximum of three projectiles in Mega Man III, disappearing if it hits an enemy or the projectile is too strong to hold up against. In both games it is Dive Man's weakness.

• Rain Flush: Rain Flush is Toad Man's Special Weapon. It was originally created to cause rain for agricultural purposes, but the water was replaced with powerful chemicals to be used as a weapon against Mega Man in Mega Man 4. It fires a capsule into the sky, which then creates an acid rainstorm that covers a wide area and can't be avoided. The rain affects all things on the screen, including shielded enemies like Mets and Pakatto 24, and it can hit several times before disappearing. The weapon can hit Drill Man while he is underground and pierces Skull Man's Skull Barrier.

• Tundra Storm: Tundra Storm is Tundra Man's Special Weapon in Mega Man 11. With this weapon, Tundra Man is able to damage any enemies directly above and below him by shooting out a large column of snow and cold air. Larger enemies are frozen solid by this attack, and smaller ones are destroyed instantly.

Trivia

• At one point in development, Dr. Cossack was actually named Dr. Vice (Dr.ヴァイス).
