MegaMan.EXE's speech right before his heroic sacrifice at the end of 3.
MegaMan.EXE: Lan, these are my final words as Hub Hikari. Lan, you have to go on living and have a future! I will always be with you. I already died once and came back as MegaMan.EXE. Meeting you, playing with you, fighting with you, everyday that I spent with you was a happy one and finally I have been able to meet you face-to-face. I've never been happier. Lan, you will be able to make so many more people happy! I'm so proud to have had a brother like you. And now I must speak as MegaMan. Just because I'm gone, don't you skip your homework, and learn how to wake up by yourself! Lan, nothing could replace the days I spent with you. Thank you. Good bye, Lan!
