Hero Theme

The "Hero Theme" is a song heard in the Mega Man Battle Network series. It is usually a more epic remix of the main theme heard on the Title Screen, and is usually played when a character or characters comes to the timely aid of Lan Hikari and MegaMan.EXE, uplifting their spirits in dire times or saving them from an otherwise life threatening situation. In Mega Man Battle Network 2 and 3, it is called “Proof of Courage” (勇気の証), in 4 it is called “Under Justice” (正義のもとに), in 5 it is called “You’re Not Alone!” (一人じゃないんだ!), and in 6 it is called “Hero!” (ヒーロー!). In Mega Man Network Transmission, the song is simply called “Title” (タイトル) and is a non-vocal remix of “Kaze wo Tsukinukete” that is also used in the Title Screen. This marks the only time the song is heard outside of Japan.

The original game lacks a dedicated hero theme, and instead uses the song “Running Through the Cyberworld”, the theme of NumberMan.EXE’s level earlier in the game.

Mega Man Battle Network
“Running Through the Cyberworld” plays when Lan saves MegaMan by installing the Hub.BAT, revealing that MegaMan is Lan’s twin brother Hub given new life.

Mega Man Battle Network 2
“Proof of Courage” first plays when ProtoMan.EXE holds ShadowMan.EXE in place for MegaMan to fire the “anti-ShadowMan” battlechip Ultimate Blaster when ShadowMan invades the Mother Computer for Gospel. This plan fails however, as ShadowMan uses his minions to take the hit for him.

It later plays when Mayl Sakurai, Dex Oyama, and Yai Ayanokoji confront Lan about taking on Gospel’s headquarters on his own, and then slightly later when Roll.EXE, GutsMan.EXE, Glide.EXE, and ProtoMan.EXE save MegaMan from copies of themselves.

Mega Man Battle Network 3
“Prof of Courage” plays at the end of the game, when MegaMan sacrifices himself to save Lan from the bowels of Alpha. Lan pleads MegaMan, his brother, to not leave him but MegaMan tells Lan how much he enjoyed his life with him and that he will always be with him, before overloading his remaining power, opening a hole in Alpha just long enough for Lan to escape.

Later, when Lan is talking to MegaMan in spirit, promising to do things MegaMan would always nag him about such as homework and waking up on time,
