LarkMan.EXE

LarkMan.EXE, known as SwallowMan.EXE (スワローマン) in Japan, is a NetNavi that appears as an optional boss in MegaMan Battle Network 5 (in UnderNet 1). He is referenced on the SciLab BBS as a "cyber-lark" that someone saw flying into the UnderNet. The discussion then starts to be about the UnderNet rather than Larkman himself, though.
