ProtoMan.EXE

ProtoMan.EXE, known as Blues.EXE in Japan, is a NetNavi from the MegaMan Battle Network series operated by the ace NetBattler Eugene Chaud (Ijūin Enzan) and rival of MegaMan.EXE. ProtoMan specializes in swords and uses many sword-type BattleChips. ProtoMan appears in many stories of the Battle Network series, but the player can only play as him in MegaMan Battle Network 5 and MegaMan Battle Chip Challenge.

In Design, Protoman.EXE seems to be a combination of both the Classic Series' Protoman, and X Series Zero, Despite there being a Battle Network equivalent of Zero. Characteristics from Protoman include the Visor, Shield (only used in battles), Rival/Hidden helper to Megaman, cold, professional attitude towards others, and habit of showing up at the last minute. From Zero, he borrows the long ponytail (albeit gray), and affinity for blade weapons. The Red Colorscheme is taken from both characters.
