Mega Man V introduced us to the Stardroids a group of alien robot masters. In fact, there are 10 of them with 9 of them being named after planets in our solar system. Jupiter was one of the 9 named after planets, and he made his debut in Mega Man V for Game Boy.

Background- After the events of Mega Man IV for Game Boy Dr. Wily discovered or unearthed the alien robot Sun Star. Wily discovered that Sun star was made out of alien material and general weapons did not hurt him. Wily used Sun Star to create 9 new robot masters the stardroids.

Jupiter was created among the 9 using Sun Star as a template. Wily created Jupiter with the ability to fly using a high powered jet pack. Terra, the stardroid leader took 4 stardroids to attack the Earth in the first wave. Jupiter was not in the first wave.

Instead Jupiter took over an old alien fort on the planet Jupiter his namesake planet. His base has lightning and ice in it. He noticed that Terra defeated Mega Man. However, Jupiter found out that Mega Man's weapons had been changed to damage the stardroids. Even after Mega Man defeated the first wave he eagerly awaited his arrival thinking he could defeat Mega Man. Instead he was defeated. His CD data suggest he is still alive and still works for Wily in some way.

Appearance- Jupiter is a human/avian hybrid type robot master. He has yellow talons as feet. For his helmet it looks like he has a yellow beak that goes over his face. He has a slim human like face, and human like hands. He has cannon on each of his arms that he uses to create electricity. On his back he has high powered jets. His armor is mostly green, aqua, and yellow.

Personality- Despite having responsibilities he does not take like seriously which can get on Terra and Wily's nerves at times. He loves to do air tricks with his jet pack as he can go any speed he wants too. He also can be reckless as he looses valuable items at times. However, he is confident in his abilities and believed he could defeat Mega Man. He is also loyal to Terra and Wily. It is hinted that he does not like Gyro Man because he considers propellers to be ancient.

Attack- Jupiter has a simple attack pattern, but he can be tricky. He spends most of his time fighting in the air. It can be tricky to see were he will stop to fire his most dangerous attack. Jupiter's most dangerous attack is his electric shock weapon. Jupiter has two versions of this attack. One version is he will create a powerful lightning bolt and cause it to hit the ground. This attack causes lightning to spread and linger across the floor. The other version Jupiter tries to hoover over the player and strike them with lightning. He can also charge up his lightning attacks when he is charging he is immune to weapons.

Weakness- Jupiter is weak to the Bubble Bomb. The Bubble Bomb can reach upward and hit him when he is in the air. The Bubble Bomb messes with his gravity and jet systems. Also since it is water/soap based and he is electric it temporarily shorts him out. Thus, he is also weak to salt water since it is also water based it will also short him out.

If the player defeats Jupiter they will get the powerful electric shock weapon. The player can fire a lightning bolt and can even hold the lightning bolt to create an electric stream for a few seconds. This is a useful weapon against heavy armored enemies.

CD Data

He can fly very high and he can electrocute enemies with his electric shock.

Good Point- Speed

Bad Point- looses things important

Likes- acrobatics

Dislikes- turbulence

His dislike for turbulence is due to when he is flying high sometimes he hits turbulence which can make him sick until he gets out of it. It is hinted he does not get along with Gyro Man. As stated he considers Gyro Man's propeller to be ancient and Jupiter has an advanced Jet pack. It could also be that he knew that Gryo Man was originally built with a jet pack but due to cost Wily gave h im a propeller instead. Gryo Man used to be envy of jet packed colleagues but he is proud of his propeller.

Jupiter is named after the planet Jupiter. Jupiter being electric is likely a reference to how Jupiter is known for having electric storms that produce lighting on it. In fact, the planet Jupiter is known for its spots on it that are basically storms that produce a lot of lightning. His stage having Ice in it is also a reference to how Jupiter being the 5th planet from the sun is very cold, but not as cold as some of the other planets.

After the events of Mega Man V his CD data suggest he is still alive. It is likely that he still works for Wily in some way. However, what his job actually is has not been confirmed. He is loyal to Wily and to his superior Terra. This concludes the Jupiter Biography.
