The Protomen/Heartwarming

In General
"When I was younger, things were different And a man was allowed to be a man But I grew up too fast, like I was racing with the devil I've felt the blade so many times Emily girl, won't you take my hand and we'll ride Across the barren face of this desert road You set my wheels on fire I'll rev my engine till the sound is just deafening Emily, girl, I swear we'll make it out of this wasteland..."
 * Their fans' devotion.
 * The amount of attention their pages have gotten on this site.
 * At one show, Panther fell ill to biological weaponry and was unable to sing, and the Nightwalker stayed behind to tend to him. So KILROY recruited two audience members. One, codenamed the Ringer, played keyboard on the Stand. And the other, codenamed Steve, played Megaman in Vengeance. The next day, Panther personally thanked them, especially Steve...and called him back up for an encore.
 * Not to mention that they stayed an extra day and played an extra set after the whole festival was officially supposed to end.
 * In universe, Emily's devotion to Tom, and Light and Joe's passion for saving the City.
 * On March 4th, 2011, they started a pledge for $8,000 to help finance a documentary about the band and set it to run for 29 days. The goal was reached, and surpassed, within five hours. The final total was over $30,000.
 * Demon Barber comforting Commander after he lost his beard to the robots, in a Shout-Out to Top Gun.
 * Beard's Going Nowhere is mostly fun. Then you get to the parts involving Emily, and it becomes funny, sweet, and heartbreaking all at once.

"K.I.L.R.O.Y.:"
 * The band singing Happy Birthday to the Gambler.
 * At the Act I Vinyl Release Show (the first official release of Fade to Phil), after Due Vendetta, Panther announced "this is how the album really ends" and launched into a phenomenal cover of Against All Odds by Phil Collins. But what really pushes it into Heartwarming territory?

Act I
"Megaman: "Even here, it is not safe...Even this grave has been defaced. Someone has written here, on this stone...in some angry hand... Hope rides alone!" Light: "You have heard me tell this story many times before you sleep. No matter how dark this city gets...even now, there's hope for man...""
 * The Will of One:

"Protoman: "If these people tell this story to their children as they sleep, maybe someday they'll see a hero is just a man who knows he's free.""
 * Megaman's refusal to fight Protoman counts. They are brothers.
 * Proto's determination to help the City somehow even as he's dying.

Act II
"Light: The one I love, she works so hard...works her fingers til they bleed...Some of the pain that she endures would bring a strong man to his knees. And I only want to help..."
 * Dr. Light's motivations for building the robots--in memory of his father, who died in the mines, and to prevent his girlfriend Emily from suffering in the factory.

"So kiss me fast cause there's no time to lose/Leave the light on, I'll come back for you/When everything is said and done, I swear I'm gonna make it right..."
 * Emily's utter devotion to Light--she died for refusing to leave him.
 * Joe's speech to the girl in the bar.

"So kiss me fast cause there's no time to lose/I promise someday I'll come back for you/And if I die, don't blame yourself; we all do what we think is right..."
 * The prototype lyrics, too.

"Joe: "You and I...we'll bring back the light...""
 * The image of Light and Joe working together to attempt to save the City is very sweet. The singing helps, too; you can feel the bond of trust between them though they've only just met.
