Treble is the faithful companion of Bass and a villain in Megaman video series. He serves as the complete opposite version of Megaman's Rush.
Treble seems to have roughly the same functions as Rush. Treble is shown that he can fly, shoot a powerful laser out of his mouth, and a few other abilities. But the most notable ability is that he can merge with Bass to form Super Bass. When the two merge, all of Bass' powers are increased to a great amount.
