ProtoMan risking deletion just to save a little girl's Net Navi.
Raoul saving Laika from falling support beams.
Maylu and Roll trying to Cross Fuse just to help Lan and Mega relax from most of their time Net Saving.
Chaud and Dark ProtoMan's Battle in the Center of the Mind. All of it. Especially the final portion, when Chaud corners Dark ProtoMan on the roof of his old home. Chaud starts walking over, and Dark ProtoMan, by this point desperate to keep him away, fires a shot at him. Chaud just takes it, and, despite the pain, keeps walking. Dark ProtoMan starts panicing and fires blast after blast, to little or no effect. And when Chaud emerges from the smoke, he's transformed as if he'd successfully preformed Cross Fusion. Dark ProtoMan freaks out and stabs Chaud... which does little more than crack his visor. Chaud continues to approach, and Dark ProtoMan, now trapped, starts screaming, just as the sun peaks out over the hills. In the real world, we see Lan as MegaMan, who, in spite of being strangled, gets a hand on Dark ProtoMan and starts purifying his code. And then we see what Chaud did to Dark ProtoMan, he gave him a hug. thus turning Dark ProtoMan to dust and restoring ProtoMan's original program. Now that's friendship at it's finest!
