ProtoMan Muramasa Style

I just... follow Chaud's orders...
~ Proto Man regarding his orders to delete Mega Man


The NetNavi of Eugene Chaud, ProtoMan.EXE is is one of MegaMan.EXE's greatest rivals and Proto Man's Battle Network counterpart. Completely loyal to his NetOp, he follows every one of Chaud's orders to the letter and the pair have excellent synergy due to the extensive time they spend practicing every day. Although his ruthless tendencies initially rub Mega Man and Lan the wrong way, Proto Man eventually becomes one of Mega Man's closest associates and most trusted allies. Nevertheless, the crimson Navi tends to chastise his blue counterpart for being too naive and trusting at times, but they generally come to an agreement by argument's end.

Attack Potency: Multi-Universe level (Considered to be one of the few Navis who can challenge a serious MegaMan.EXE and is an Ultimate Program holder in the anime, putting him in the same league as Bass, though Bass is significantly stronger)

Speed: Massively FTL+ (At least 2.6 Billion C via scaling from MegaMan.EXE, who fought Geo Stelar and ran through the entire Cyber World in a short amount of time in the manga)

Lifting Strength: At least Class 50, likely much higher (Can easily wield weapons as large as himself with little effort)

Striking Strength: Multi-Universal (On par with MegaMan.EXE)

Durability: Multi-Universe level (Has tanked hits from MegaMan.EXE in a serious spar and survived his battle with Nebula Grey in canon)

Stamina: High, rarely shown tiring in the series and easily fights through entire gauntlets of viruses and HeelNavis every day with little rest in between. Fights continuously for ten hours every day alongside NetOfficial work and is only shown fatiguing in the face of powerful foes like Nebula Grey or when he's forced to take hits.

Range: Extended melee range with swords. Interplanetary with projectiles.

Standard Equipment: A WideSword (a blade designed to hit across a wide area, the Muramasa blade (a traditional Japanese blade that increases in power as its wielder takes damage), the Proto Shield (a shield attached to his right arm that can expand and block frontal attacks as well as redirect the force of the attack as a rapid kinetic blast at the opponent), A generic Buster (an arm cannon for ranged combat), Various Battle Chips

Intelligence: ProtoMan.EXE is extremely capable combatant who regularly fights entire gauntlets of Navis and viruses for ten hours a day to hone his skills. He is so experienced that he can work well even without his Operator, a trait only shared with MegaMan.EXE and SoloNavis like Bass.EXE. He is able to make cold and callous decisions if necessary and will follow every order to the letter unless he feels that said order will do more harm than good (which is rare). He is also a master swordsman and executes maneuvers speeds that few Navis can replicate, generally eliminating most foes with a single slash.

Weaknesses: Is sometimes a bit too obedient for his own good. His constant training has made him predictable at times due to having his combat patterns ingrained in him. The Proto Shield will only block frontal attacks and can be overwhelmed in certain situations. Heavy preference for melee combat has left him lacking in ranged combat against foes like MegaMan.EXE and often forgoes the use of Battle Chips unless it is deemed necessary.
