If you know anything about Mega Man, then you probably already know that much of this stuff is taken from the Mega Man X timeline.  So, here's Z-R0E's original FAQ that should explain everything.  
 Since I'm completely SICK of describing how my armor works, and my relations 
  to the real MMX storyline, heres a few responces to the damn FAQ's I here. Q: Hey Zero, weren't you sad when Iris died? Q: I thought Iris died in MMX4, so how is she your mom? Q: Why do you look so much like Zero then if your not him? Q: How can you be his son if Zero is a robot? Q: Huh? How? Q: If your armor connected to you mentally, how can you be always changing 
  the connections and adding stuff to it? Q: Using your locker description, then couldn't some one else go into the locker 
  and take it? Q: What happened to all the other MM/MMX charecters?  Q: Well, long answer, but who's X-Idus and where's Aurora? Q: Whats an official charecter, and are there anyothers? Q: What the hell was that 2nd form stuff during the Rebirth fight(took 
  place in AE
  
  )? Q: In your universe, what's a Maverick? Q: What's your exact definition of a Make-Shift? A few quick things about Z-R0E 
 
  A: Fuck you and die. I'm not Zero, I'm his son. Iris was my mom. My dad was 
  my idol, but I never really knew Iris.
  A: Sigma has come back 3 times, Wily countless, Zero 2-3 times(depends what 
  you do in X3), timesand Protoman a few times. So, why can't Iris?
  A: Like I said, I'm his son, I inherited his armor.
  Ok, now this is where shit gets deep. This is my MMX Universe. Everything has 
  happened that happened in the real MMX Universe, and more. The first, and main, 
  difference is that Reploids are not robots. Here, Reploids were origianally 
  made by man, but with the ability to reproduce. Their armor is also not connected 
  to them.
  A: Reploids have a mental bond with what is believed to be a subspace pocket. 
  They can use this bound to call on armor from sthe pocket, or where ever it 
  is, much like Sho can in the anime series Guyver. Since the armors making a 
  dimensional jump, it creates a small explosion around the caller. Having their 
  armor doesn't drain or tire a Reploid anymore than a human's heart beating does.
  The armor is living metal. No, like like the T-1000 from Terminator. When I 
  say alive, I don't mean it can move and such, it grows. It has a seperate set 
  of genes. A child's armor is the combonation of his parents armor's genes.
  A: In my Universe, Reploids learned how that if they changed there armor around, 
  then put it back into subspace, it won't change. It makes since. Think of it 
  like this, if you take a gun from a locker and add a silencer, put it back in 
  the locker, come back a few hours, it'll still be on, right? Same type of thing.
  A: Each persons genetic makeup is different, and so is every Reploids. The "subspace 
  pockets" are each attuned to that particular Reploids genes. So, using 
  the locker comparrison again, consider it a padlock.
  A: Well, after MMX4, Zero reveals to X that he is the leader, and always has 
  been, of the Maverick(special note: Since in my universe Reploids aren't robots, 
  they can't malfuncion. So, here a Maverick is some one who fights for Reploid 
  dominance becuase they belive that Reploids are the superior race). Zero explains 
  to X that all along Sigma has been nothing more than a lackey of Zero, and that 
  X fell for it. X of course gets mad. A war breaks out between the Repliforce 
  and the Mavericks. While Z-R0E is off on a moon of Aurora, training with Vile, 
  Zero's stronghold is attacked by a full scale invasion. Zero goes out to take 
  X on 1vs1 in the middle of the battlefield. The fight between them lasted for 
  hours, and by now over 1/2 the soldiers from both armies were dead. Zero was 
  wining, but then Z-R0E walked onto the scene, having justed landed back home. 
  Some Repliforce went to attack him, but Zero killed them before they reached 
  Z-R0E. As Zero fought to save his son, X blasted and killed Zero. X then ordered 
  a retreat, thinking the war was won.
  X was wrong though. Z-R0E now assumed role as leader of the Mavericks. Though 
  he was only 17 at the time, all Mavericks would agree that he was as good, if 
  not a better leader than his father. Z-R0E knew his father died saving him, 
  and his mother had died saving Zero. Z-R0E then decided that emotions were pointless 
  and caused nothing but death, either mentally or physically. From that day on, 
  Z-R0E never cared about anyone.
  Z-R0E later attacked X's fort by himself, killing 80+ guards. When he saw X, 
  he had a flashback of X killing his father. Wehn Z-R0E came to his hands were 
  dripping blood, X's body was 3 feet away from him, and X's head was detached 
  and under Z-R0E's foot, smashed. That night haunts Z-R0E to this day because 
  he is not sure exactly what he did to X.
  The Mavericks pushed on harder to overthrow the Repliforce, since they were 
  the Mavericks first roadblock in their plan for inter-galaxy domination. Repliforce 
  knew their end was sealed and decided to blow the planet up, thinking it was 
  the only way to stop the Mavericks from their plan. Their plan was to be executed 
  on October 10, but before they could do it, on September 30, the planet exploded. 
  Z-R0E and X-Idus were the only two to survive.
  A: After Reploids started breeding, and the Mavericks startd coming about, humans 
  feared for their excistance. They thought that all Reploids thought as Mavericks 
  did. So, through a bloody war, the humans exiled the Reploids to a barren planet 
  called Aurora. It took some years, but the Reploids eventually set up colonies 
  and began to live there. The Mavericks wanted to go back to Earth and gain revenge 
  and conquer to humans. The other Reploids, the Repliforce, spent all their time 
  trying to save the humans by stopping the Mavericks from leaving Aurora. So, 
  no Reploid has ever made it off Aurora, until it blew up, then only Z-R0E and 
  X-Idus escaped.
  X-Idus is a charecter in my story I made awhile ago. In AE he's played by my 
  friend who's grounded from his comp all summer. X-Idus and Z-R0E grew up together, 
  and now X-Idus is's Z's left hand man. Vile was basically Z's right hand man 
  and the three of them became best friends, but someone had to stay behind to 
  launch the ships off, so Vile told them to go.
  A: An official charecter are people that are either in my story, or I have seen 
  that follow the guidelines(like X is dead, Reploids aren't robots, etc). If 
  they aren't already in my story, I plan to add them later. You must have an 
  original spirte of your charecter(not just a repaint either). You must have 
  some background for your charecter also. Also, if you want your charecter in 
  my world, you gotta be open to change. Once they enter here, they are mine to 
  play with. You have say of what goes with your charecter, buit ultimately, I 
  decide what happens. A list of all official charecters is on the Character page.
  A: During the original fight with X, Z-R0E rembered getting extremely angered 
  at the memory of X killing Zero. The next thing Z-R0E rembered is that his hand 
  were dripping blood, and X's head was under his foot. Time passed, Rebirth came. 
  Rebirth kept saying show me him, wanting revenge on the form of Z-R0E that had 
  almost killed him. Then, when Z-R0E found out Rebirth was X, Z-R0E basically 
  flipped out, and went to his 2nd form. He easily crushed Rebirth in this form, 
  but it also left Z-R0E really messed up. Instead of his 2nd form coming from 
  a sub-space pocket like his normal armor does, it is his normal armor moving 
  and growing. And since his armor is attached to him, it hurts Z-R0E like crazy(imagine 
  if you just grew an extra 10 or so feet in about 1 minute, you'd hurt like crazy)
  A: I ALREADY ANSWERED THIS! *sigh* A Maverick is a Reploid who believes that 
  Reploids are the better species, and that humans and all other lower lifeforms 
  should be their slaves.
  A: After all the original Reploid-Making factories were closed, Zero made sure 
  to destroy them on his path of domination. The humans needed something to battle 
  against the Mavericks, so they tried to recreate them like they were originaly. 
  But, with Dr. Cain now being long dead, no one knew how. So, humans took other 
  humans and gave them all the armor and wepaons and other tpye things the Reploids 
  could do. The only differences were that Make-Shifts armor couldn't come off, 
  they couldn't reproduce, and they were made from other humans.To put it more 
  bluntly, Make-Shifts are humans with cybernetic parts.
  Z-R0E eyes are normally a birght, almost glowing shade of red. The madder he 
  get, the darker red his eyes get, as does his crystal. He hates cute things, 
  being mistaken for Zero, and his name being spelt with a o instead of a 0.
