|Artwork of Treble from Mega Man 7|
When used, Treble is summoned to the area in front of the player. While he's present, basic buster shots can be fired. When Treble is touched, he and Bass fuse together to enter Treble Boost form. While in this form, he can fly in any direction using the movement keys, and his shot changes to a three-way spread shot. He is also immune to knockback while it's active, and energy is drained at a rate of two units per second. Each shot deal damage separately, so landing all three shots will deal triple damage. If Treble is left idle for five seconds, or if the player tries to summon him within two tiles of a wall, he will teleport away automatically.
Treble boost is unique to other animal helper utilities as it can be used mid-air by jumping into Treble's spawn animation.
- If the player is caught by a Bunby Catcher while in Treble Boost form, they will be carried along at a lower speed while still being able to move up and down.
- If Bass touches a ceiling and flies off an edge then he will no longer wobble while flying.
