Bass GS

Bass GS, known as Forte GS (フォルテエグゼ) in Japan, is a boss in Mega Man Battle Network 3 and a playable Rank S Hunter Program in Rockman X DiVE. He is the form the NetNavi Bass.EXE takes after he has absorbed the Gospel Bug Beast.

Mega Man Battle Network 3
After Alpha's destruction, Bass was near death, but was found by a remnant of the Gospel Multibug Organism, who merged with Bass and saved his life, forming Bass GS. After Serenade's defeat, Serenade mentioned that he did fight against Bass in the past, only winning after a battle that lasted days. Bass GS then consumed at least 300 BugFrags, courtesy of MegaMan, and attacked MegaMan to test this new power. After a close battle, Bass lost, and it is revealed that he had lost most of his memory while fused with Gospel. He then vanishes from the Secret Area.
