The Journal of Dr. Cain (ケイン博士の日記) is a feature from the first Mega Man X game detailing what happened before the game from Dr. Cain's point of view. It is present in the English SNES manual, the Japanese Windows version manual, and the book Compendium of Rockman X.

|April 8th||"Still nothing. For the last month, I have been sifting through the dirt trying to find a fossil record which would verify my findings on Mesozoic plant life, but so far I have come up empty. Tomorrow I'll move my archaeological dig to a new site. Maybe I'll have better luck."|
|April 9th||"Set up camp at the new site and laid out a preliminary gridwork for the dig. I got some odd readings at location E-46. It looks like something metallic is buried several meters below the surface. I think I'll begin there tomorrow."|
|April 10th||"I can't believe what I found! Several meters below the surface was the remains of a lab. Although most of the lab was damaged, I did manage to find papers that indicate that it belonged to the famous robot designer, Dr. Thomas Light. I've begun to review what is left of Dr. Light's notes and it looks like he was onto a major breakthrough. The notes keep referring to "the capsule"..."|
|April 13th||"I found it. Standing 14 meters high and 8 meters wide, the capsule was hidden underneath a collapsed ceiling. Even underneath all the rubble, the capsule has remained intact and was still running some sort of diagnostic when I found it. There is a warning on the capsule, but all the indicators on the capsule show green. It should be safe to open it. I'll know tomorrow."|
|April 14th||"Today I met "X". Not simply a robot, X is something totally different. Light has give him the ability to think and make his own decisions. At times, X seems more like a man than like a machine."|
|April 15th||"Light was a genius! I've been going over his design notes and they are a quantum leap beyond anything the world has ever seen. Using them as a guide, I may be able to replicate his design and integrate them into a new generation of robots. I'll begin transporting X and the rest of Dr. Light's things back to my lab tomorrow."|
|November 22nd||"With X's help I have completed my first "Reploid." Although I don't completely understand how all of Dr. Light's systems works, I was able to make some minor modifications and the reploid seems to be functioning perfectly. His strength and intelligence seem limitless and he is fully able to make his own decisions. In fact, we got into our first argument. How intriguing!"|
|January 3rd||May 3rd||"The new reploids have been running off the assembly line for several weeks. It's amazing how easily they have been able to adapt to even the most difficult jobs. It still is a bit odd to see them working side by side with humans, but everyone seems to be happy to accept them."|
|February 16th||July 16th||"Three reploids went "maverick" today and injured two people before they were stopped. This is the third instance of this type of behavior and I still have no idea of what is causing it! There is some talk about stopping the assembly of any more reploids, but I don't think it will happen. Maybe we've become too dependent on them...."|
|November 20th||"The council has now decided to set up a group of "Hunters" to destroy any maverick before it can cause injury. The reploid named Sigma has assigned to lead the Hunters. Sigma is one of the most intelligent reploids I've created and contains my latest circuit designs. His systems should be immune to any problems."|
|May 16th||December 10th||"It's been two months since Sigma took control of the Maverick Hunters and he and his hunters have been able to prevent any further injury to the population. Everyone is starting to breathe a little bit easier....|
I am a little worried about X. He seems unsure of his place in life and what Dr. Light had planned for him. But given time, I'm sure he'll find his way...."
|June 4th||July 4th||"My worst nightmare has just come true. Sigma went Maverick today and took most of the other hunters with him. His motives are unclear, but it seems that he "decided" that humans are inferior and limiting the growth of the Reploids. For that reason, he decided that all humans should be eradicated.|
Most of the population is in hiding or trying to flee the city. I'm not sure how long we can hold out against Sigma's forces. I fear I've built the reploids too well."
"X is taking the news of the war very personally. He wants to join ZERO, the new leader of the Maverick Hunters, when he goes after Sigma. I'm doubtful of their chances, but I won't stop him. Something has to be done...."
Note: The dates from the Journal of Dr. Cain are given simply as month and day. The years in the game and manual are stated simply as "21XX." However, the timeline of events are believed to take place in the 2110s, as the copyright of Dr. Cain's computer in the opening scene of the first game shows three years when booting up: 2105, 2109 and 2114. (see game script.)
