Flight ability
Treble can fly to transport Bass like the Rush Jet. This function was only used in the opening animation of Mega Man 8. Appearances:
 * Mega Man 8

Super Adapter
The Super Adapter allows Treble to merge with Bass, acting like a armor that increases his strength and gives him the ability to fly. He can also use a flying fist attack and unlike Mega Man's Super Adapter, Bass has the ability to fire either a regular charged shot or a rocket punch, as opposed to just the rocket punch. It was created by Dr. Wily using the parts Bass had stolen in Dr. Light's lab in Mega Man 7, which where originally planned to enhance Rush's Super Adapter. Bass used this in the second battle against Mega Man in the Wily Castle.

Appearances:
 * Mega Man 7

Treble Boost
The Treble Boost, known as Gospel Boost (ゴスペルブースト) in Japan, is an improved version of the Super Adapter used by Bass in his fight against Mega Man in Mega Man 8. He can fly as long as he wants, as well as being able to fire powerful charge shots and laser beams. In the games Mega Man & Bass, Rockman and Forte: Mirai Kara no Chousensha and Mega Man 10, Bass can buy this ability in the item shop, which allows him to fly for a limited time and shot in three directions at the same time.

Treble Item
Treble Item is an item that Bass can buy for 20 Screws in Reggae's shop. When used, Treble appears and gives a random item to Bass, similar to Mega Man's Eddie Call.

Appearances:

Treble Rescue
Treble Rescue is an item that Bass can buy for 30 Screws in Mega Man 10. It acts similar to the Beat Call, saving Bass from bottomless pits using the Treble Boost for a few seconds.

Trivia

 * In Japan, Treble's name is Gospel, which was left untranslated in the MegaMan Battle Network series.
 * Treble is one of the many characters who have music-inspired names, Treble being a musical term and Gospel a type of music.
 * Despite the fact that Bass made a small cameo in Mega Man 9, Treble was nowhere to be found.
 * In MegaMan Battle Network 2, Gospel appeared as a Multibug Organism and the final boss in the game. In MegaMan Battle Network 6, the Cybeast Gregar appeared as part of the main plot and the final boss. Both of the these characters' designs are based on Treble.
 * When using the Treble Boost, Bass' Wings are smaller in Mega Man & Bass than in Mega Man 8.
