Sirius

Sirius is a character of the MegaMan Star Force series, and appears as the secret boss of Shooting Star Rockman 3. He is the controller of a black hole, and uses it to attack other planets and stars, sucking them up and adding them to his "collection". When he attacks the Planet AM and Planet FM, the Satellite Admins and Cepheus turn to MegaMan (Star Force series) for aid.

Sirius also happens to have rebuilt copies of the other EM Beings throughout the game, and the player must defeat these copies in order to fully progress through to the Black Hole Server. The rebuilt forms are labelled with "R" at the end of their names, save for Apollo Flame. After defeating these forms scattered throughout the EM World, the satellites that pinpointed their location now generate image data for the player to battle. When Sirius is finally defeated, he gives MegaMan the Mu Metal and transfers his powers to Meteor G out of spite, causing Crimson Dragon to eventually upgrade itself into Crimson Dragon SP.

Abilities

 * Super Armour&: Sirius cannot flinch.

 * Glass Barrier: The middle row of the battlefield is protected with regenerating, 1 HP glass barriers, which can be avoided through the use of two Area Eaters or one Double Eater.
 * Format Laser: Sirius fires a narrow yellow laser at the player from his wings, canceling any special panels, Barriers, and Auras that it comes into contact with.
 * Wing Assault: Sirius launches his wings, which then fly down different columns at random. They can be destroyed or dodged, but cannot be blocked.
 * Wing Formation: Sirius launches his wings, which then shuffle about the field, firing lasers in different formations, covering different portions of the player's row.
