The Jewel Satellite (ジュエルサテライト Jueru Sateraito) is Jewel Man's Special Weapon from Mega Man 9. When activated, it summons four jewels that orbit Mega Man or Proto Man. When the shield is up, it can be launched as a projectile in the direction the user is facing.  As with most other shield weapons, the user can move while using the Jewel Satellite.  Despite only inflicting two points of damage, Jewel Satellite can destroy multiple weak enemies without being destroyed itself.  It also deflects/destroys most projectiles. Since the weapon's energy only depletes each time it is activated, it is possible to keep it up during a whole section of a level, and it will not disappear unless the player transitions to a new set of screens or touches a tough or invulnerable enemy.

Jewel Satellite is Plug Man's weakness; not only does it do heavy damage to him, but it destroys all his projectiles too.  It is also good against Fake Man, as it can block all of his attacks. It also does 2 damage to Jewel Man.

  • For Spike Pushers and Wily Machine 9's first phase, both bosses do not have data for them because they must be damaged with their own weapon or obstacle -- the Jewel Satellite cannot inflict damage to them directly.


Activating the Jewel Satellite costs four units of weapon energy. It can be used seven times with a full weapon energy gauge.

  • The Jewel Satellite is often considered to be the best shield weapon in the classic series, and possibly the franchise, due to its immense utility, the fact it addresses most flaws other shield weapons had in previous games, and its lack of any true drawback, except for its surprisingly low damage in relation to its high cost.
