Lan Hikari
Lan Hikari is the fifth-grade son of the famous scientist Dr. Yuichiro Hikari and the grandson of Dr. Tadashi Hikari, the inventor of the PET. Given his family roots, it was only natural for Lan to strive to be the greatest NetBattler the world had ever seen. And he’s on his way, provided he can overcome his nemesis, Chaud Blaze and ProtoMan.EXE. Lan forms quite the bond with his NetNavi, MegaMan.EXE, and in doing so takes on a variety of crime organizations.
Lan is a rambunctious boy, daring, and well liked among his friends. When not participating in NetBattles, Lan can be found playing soccer, skating, or fending off the flirtatious advances of his close friend and neighbor, Mayl.
Mayl Sakurai
Mayl (Maylu in the anime) is Lan’s neighbor and classmate at the school in ACDC town. An intelligent character determined to keep Lan out of trouble, Mayl would certainly like her relationship with Lan to move beyond friendship and gets jealous when other girls steal his attention from her.
Mayl’s NetNavi, Roll.EXE, is based on Roll from the other games and is primarily a support NetNavi. Roll can heal other NetNavi and even be used as a Battle Chip that deals a powerful attack that not only damages enemies but also heals MegaMan.EXE.
Dex Ogreon
Dex is both friend and rival to Lan at school and within the Net, often battling his NetNavi GutsMan.EXE against MegaMan.EXE. Despite his size and abrasive attitude, Dex is a big softy, always willing to do what he can to help Lan and his friends, especially if that someone is Mayl.
Dex’s NetNavi, GutsMan.EXE, mimics the size and power of Dex and is predominantly a melee fighter, reliant on his giant fists and powerful hammer to overcome his sluggish movement speed. Lan and MegaMan.EXE can battle against GutsMan.EXE in each of the first four games in the series.
Mr. Match
Mr. Match is an early member of the WWW and uses his NetNavi FireMan.EXE to support Dr. Wily’s search for the LifeVirus components in the first game. Apparently left to smolder, Mr. Match returns in Mega Man Battle Network 2 with HeatMan.EXE, then again in the third game with FlameMan.EXE before finally being taken into custody. Nevertheless, Mr. Match also appears in Mega Man Battle Network 4 with FireMan.EXE.
FireMan.EXE has veritable flamethrowers for cannons and is capable of multiple close-range fire-based attacks. He is responsible for the outbreak of seemingly inexplicable oven fires during the early part of Mega Man Battle Network.
