Background

Dr. Mikhail Sergeyevich Cossack is a character from the original Mega Man series. He first appeared as the central "antagonist" in Mega Man 4, but later became an ally of Mega Man, creating Beat as a gift to assist him.

Dr. Cossack is a Russian robotics engineer that graduated in the Ural Technical University. He won many awards during his career, including the Brzezinski Science Award and the Scientific Achievement Award. He lives with his daughter, Kalinka Cossack. His hobby is watching ballet.

This dropdown contains the synopsis of Dr. Cossack’s story. Read at your own risk as you may be spoiled otherwise!

Mega Man 4 In Dr. Cossack's debut, he sent a message to Dr. Light stating that he has created eight Robot Masters (consisting of Bright Man, Toad Man, Drill Man, Pharaoh Man, Ring Man, Dust Man, Dive Man, and Skull Man) and sent them to take over the world, in order to show the world his genius. Mega Man set out to defeat the eight new Robot Masters, and made his way to Dr. Cossack's Citadel. Just as he was about to defeat Dr. Cossack in the Cossack Catcher, Proto Man appeared with Kalinka and revealed the truth: Dr. Wily had kidnapped Kalinka and forced Dr. Cossack to work for him as ransom. Mega Man 5 After Dr. Wily's defeat in the previous game, Dr. Cossack built a robotic bird called Beat for Mega Man to assist him in protecting the world. Dr. Cossack does not appear in the game, only being mentioned in the manual as informing Mega Man of Light's capture, and increasing the firepower of his Mega Buster's charge shot. In the Rockman Complete Works version of Mega Man 5 and its port in Mega Man Anniversary Collection, Cossack serves as the main guide in Navi Mode. Mega Man 11 While not appearing in-game, Dr. Cossack is mentioned as the manufacturer of Tundra Man, one of the eight Robot Masters that can be fought. Wily & Right's RockBoard: That's Paradise Dr. Cossack is one of the playable characters. His objective is to build a new lab to continue his experiments.

With Mega Man needing to deal with the likes of Mothraya, Square Machine, and Cockroach Twin), Divine Protection (After defeating ViA■ and destroying the Robot Destroy Program within him, The Player was able to fully correct the Deep Log in its entirety. However, Via says The Player's story isnt 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).

Resistance to Information Manipulation & Conceptual Manipulation (Can take hits from characters that 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), Plot Manipulation (As data determines one's canonicity in reality and all universes are made of data, one would need to fully change one's data in order to change their narrative. With data further being explored through here)

• 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.
