Magnet Man (Mega Man)

"I feel tense these days..."

- Magnet Man from the Mega Man & Bass CD data

Magnet Man ( or Magunettoman in Japan) is one of the 8 robot masters and main antagonists of the NES video game Mega Man 3 as well as one of the four additional bosses of the Gameboy video game ''Mega Man II. ''While once a humble android who was created to generate magnetism for Dr.Light, Magnet Man was kidnapped and reprogrammed to destroy Mega Man should he find him.

History
After his defeat by the hands of Mega Man in Mega Man 2, Dr.Wily kidnapped Magnet Man, along with 7 other robots, from his arch-nemesis Dr.Light in an attempt to defeat him. Dr.Wily reprogrammed Magnet Man and the others from simple utility androids, to violent robot masters.

Mega Man 3
Dr.Wily assigns Magnet Man to an old robot factory to command all of the basic enemies in the game. Mega Man infiltrates Magnet Man's base to defeat him and gain his powers. Once Mega Man enters Magnet Man's room, the latter ambushes the former as Magnet Man's reprogramming requires him to. In the game, Mega Man must use either use Spark Man or Shadow Man's (or Magnet Man's own depending on the circumstances) weapon to defeat Magnet Man. Once defeated, Mega Man obtains Magnet Man's ability to fire magnet missiles which give Mega Man an advantage against Hard Man, Doc Robot (in the form of Metal Man), Doc Robot (in the form of Air Man), and/or even Magnet Man himself depending on the circumstances.

Rematch
Once Mega Man reaches Dr.Wily's fortress, Magnet Man is revived to battle Mega Man once again. Mega Man can use Magnet Man's own weapon against him to gain the upper hand, presumably because the magnetic fields cancel each other out leaving Magnet Man vulnerable with his magnetic field disabled. After Magnet Man is defeated for the second time, he doesn't appear for the rest of the game

Mega Man II
After Mega Man reaches Dr.Wily's castle, Mega Man must battle Magnet Man along with 3 other robot masters from Mega Man 3. After Mega Man defeats Magnet Man using Needle Man's titular Needle Cannon, Magnet Man doesn't appear for the rest of the game, presumably being defeated for good.

Trivia

 * According to Magnet Man's info CD from Mega Man & Bass (or Rockman & Forte in Japan) Magnet Man dislikes floppy disks. This is because if a magnet is placed on top of a floppy disk, the magnetic radiation corrupts the data the disk contains.
 * Magnet Man is similar to Junk Man in the sense that they are both weak against electricity based attacks.
