List of Mega Man Star Force 3 Battle Cards

Overview
A list of the Battle Cards that appear in Mega Man Star Force 3.

Standard Class
There are 150 standard-class cards in the game's library, though there are also "illegal" versions of cards that may be obtained (see below).

Mega Cards
There are a total of 135 Mega Cards in the game, but only 45 of them (corresponding to the game's bosses) will be recorded in the Library. The remaining Mega Cards, including Cards corresponding to previous games' bosses, are obtained as Illegal Data.

Giga Cards
There are 33 total Giga Cards in MegaMan Star Force 3. Five giga cards exist in each version of the game as well as appearing in each version's library, while the other 11 must be obtained from Illegal Data (see below).

Illegal Cards
Some Battle Cards are only obtainable through Illegal Data. They do not appear in the Star Force 3 library, but their ID sorting is equal to the next tier of the series they come from (eg: Impact Cannon is placed directly after HevyCannon). Some bosses such as RogueZZ may yield Illegal Data containing Giga cards, on rare occasion.

Galaxy Advance
Star Force 3 also introduces the Galaxy Advance (abbreviated GA) system, which works similar to Program Advances from the Battle Network series. In addition to forming the Galaxy Advance by touching the appropriate cards in sequence, Galaxy Advance cards also appear as standalone Battle Cards as very rare Illegal Data, or within Meteor Server folders.

Galaxy Advance versions of certain bosses in the game can be powered up by quickly deleting their respective R versions of that boss. Their power maxes out when the deletion time is under 12 seconds.

Noise Force Big Bang Cards
Main Article: Noise Force Big Bang

Not technically Battle Cards, Noise Force Big Bang cards appear in the form of usable Battle Cards when MegaMan performs a counter in Vibrant Noise, Multi-Noise, or Finalized Noise Forms, or as selectable cards when accessing the Meteor Server. They are used like regular, screen-dimming Battle Cards, and occupy the same space as a standard card on the Custom Menu.

Event Cards
Special Battle Cards that are normally unobtainable, and were given out during special events in Japan and North America.
