Brother Band System (MMSF1)

The Brother Band System is the main Ability system for Mega Man Star Force.

Brother Band Stats

Each Brother has unique effects that can boost Mega Man.

In-Game Brothers

These are Brother Bands that can be encountered during the game's story. They'll gain levels as the player progress through the game, up to Level 60.

They cannot be cut until the story mode is completed. If they were to ever be cut afterwards, they can be re-Brothered by talking to that character.

Brother Band	Min. HP Boost	Max. HP Boost	Link Ability
Sonia Strumm	HP+0	HP+95	UnderShirt, if MegaMan's HP was to drop to 0, it goes to 1 instead.
Luna Platz	HP+0	HP+95	Float, MegaMan is unaffected by Poison, Gravity, and Guard Null panels. Also, MegaMan can’t be Gravitized.
Bud Bison	HP+0	HP+140	SuperArmor, MegaMan cannot flinch in battle.
Zack Temple	HP+0	HP+70	MegaClass+1, 1 more Mega Card is allowed in the Folders.

Brother Band with other Games

These are Brother Bands that can only be made with other game carts. For other version Brother Band, the Level is equal to that player's Level at the time of Brothering. For Lunar Knights, the level is dependent on that player's progress.

Brother Band	Min. HP Boost	Max. HP Boost	Link Ability
Pegasus	HP+20	HP+150	Gauge+1, Custom Gauge fills up faster
Leo	HP+20	HP+220	Attack+1, Buster's Attack stat increases by 1.
Dragon	HP+20	HP+110	MegaClass+1, 1 more Mega Card is allowed in the Folders.
(JP Only) Lunar Knights	HP+20	HP+220	Charge+1, Buster's Charge stat increases by 1.

Legendary Master Shin

Shin is a special Brother Band that could only be downloaded during events. Like in-game Brothers, he'll gain levels as the player progress through the game, up to Level 60. He can be re-Brothered at his location on AMAKEN's roof.

Brother Band	Min. HP Boost	Max. HP Boost	Link Ability
Shin LM	HP+45	HP+70	GigaClass+1, 1 more Giga Card is allowed in the Folders.

Brother Force

If a Brother card appears in the Custom Screen, it can be selected and a roulette will play. One of 6 Brother cards that Brother has will be randomly selected for the player's use.

However, if the player is On Air with their Brothers, that Brother's equipped Best Combo can be used instead.

These Cards can be turned off in the Folder.

Data Update

By going On Air with Brothers, further game data will be shared.

SP Card Records

The SP Card Records are shared between Brothers, each players' lowest recorded time will be visible. The one with the lowest records of all the players will be every Brother's maxed SP card damage.

This is the only way to receive boosted Records for the Admin SP cards of other versions, as there is no way to fight all three in one game.

Comparing Library

The Library data are shared between Brothers. All cards that haven't been registered will be filled with their name but without their image and info.
