J'onnverse Canon Notes 
Which canon?
If you only know the world of the Justice League and Batman through the cartoons of the last decade, you are in some ways lucky. Most of you, though, have at least had to puzzle through where the Batman movies don't quite jive with the animated series, and if you're a comic reader to boot, you *know* how complicated canon questions can get.
The first defining move is to say that the J'onnverse builds primarily, though not exclusively, from comics canon. Non-comics readers who want to get caught up in this canon should investigate the "must reads" listed elsewhere on this page or return to the entry page to follow the links for Martian Manhunter and Batman.
Comic aficionados will recognize that just claiming comics canon leaves lots of unanswered questions. Which retcons are followed in the J'onnverse? Which ones are ignored? There has been a certain amount of picking and choosing involved in the J'onnverse, and the most salient points are listed here:
Batman
Basically we go along with contemporary canon up to the initiation of the Bruce Wayne: Murderer/Fugitive arc. Thus major events like No Man's Land and the whole Bane episode are very much part of the J'onnverse continuity, but the whole frame up for murder is not.
Some auxiliary points regarding the Bat acolytes:
We are going with Dick Grayson becoming Bruce's ward around the age of 8 or 9, not 13 as recent retcons have claimed. Dick did go to Hudson University, but we split the difference between old canon and the retcon - he almost graduates. Dick's formal adoption in GK #17 is part of J'onnverse continuity. This and the character of Gannon Malloy are perhaps the last things we will accept from Devin Grayson's work with Nightwing. Our Nightwing is staying a cop in the 'Haven and his home and Haly's circus are all fine, and if push comes to shove, we'll "Dallas" the whole Grayson run.
Barbara Gordon is significantly older than Dick Grayson - old enough to have been his babysitter as per older canon. We are more likely to go back to Batman Family issues to get Barbara's past than to accept recent attempts to rewrite it like "Batgirl: Year One." For instance, she really was a Congresswoman once upon a time.
Our version of Cassandra Cain is adamantly the character created by Puckett and Scott in "Batgirl." The uniqueness of the character has been diluted by subsequent authors, although Horrocks has done some neat stuff. As far as we're concerned, the series might as well have ended at #37.
Robin and Spoiler and that complicated snarl are subject to very different developments in the JV than they have been in canon. The unmasking of Tim Drake in Robin #124 isn't happening. We are phasing Tim out of the suit through his own decision making (as per hints much earlier in canon that he did not want to be in the suit forever). Stephanie is not destined for the Robin suit, but we've shifted her over to the JSA.
We're still working on what we want to do with Huntress.
Azrael managed to get killed under our radar in canon because none of the JV writers was following his book. This is convenient for us. We won't argue the point.

Martian Manhunter
We are using the 1988 mini as a defining moment of J'onnverse continuity and almost everything in which J'onn appears post 1988 is probably incorporated into the J'onnverse somewhere. Where there are conflicts between the 1988 mini and the later ongoing Martian Manhunter series, we have tended to go along with the later series (so, for example, J'onn's vulnerability to fire is both psychological and physical, no matter what weird things started going on after "the Obsidian Age" in JLA).
JLA
Probably the messiest continuity we are working with. We are taking "JLA: Year One" as canon and are largely ignoring the first 200 or so issues of the first Justice League series. We pick up canon again toward the end of that series with the events that led to the formation of the Detroit team. We continue following that line of continuity into the Justice League International days (the BWAH HA HA era) and stick with that through the "Break Downs" arc. We are picking and choosing from the Justice League Task Force. "Midsummer's Nightmare," "Paradise Lost," "DC One Million" and "Foreign Bodies" are definitely in J'onnverse continuity. The current JLA monthly is included through issue #65. From that point on we might pick up parts of story lines, but obviously stories like "The Burning" do not fit into what we're doing.
Other DCU
The further the J'onnverse unfolds, the more of the larger DCU gets pulled into the story. Some canon stories, like the "Zoom" storyline and the aftermath running in "The Flash" from issues #196-206, hit after we had written beyond the events depicted there. We are gleefully incorporating JSA storylines with the same sort of tweaks we are putting in everywhere. "The Power Company" is sadly mourned, and we'll try to keep it alive here.
Among the big canon changes not happening in the JV - the whole "Graduation Day" mess with the Titans, YJ, and the Outsiders left us cold. Our Donna is still alive. We are trying to be a little more realistic about the "kid hero" situation than DC has been. We recognize an audience issue; of course teens and younger would read comics as fantasy, and wouldn't it be cool to not have to worry about parents and go have a headquarters in San Francisco, etc. We aren't writing for kids. If the Titans and YJ require adjustment to more fully address the needs of the heroes in both organizations, we won't just "reboot."

General note on canon:
Throughout the J'onnverse, the stories will have canon notes included, letting you know what particular issues are actually referenced in the stories. Any canon events happening after the year 2001 are subject to a certain amount of picking and choosing on our part. Some canon stories no longer make sense if J'onn and Bruce are together, others appeared after we had already dealt with the same material in the J'onnverse.

The Many Faces of J'onn:
Identities and Disguises
Martians have complete control over their physical structures, making it possible for them to shift shape into whatever form they desire. This ability apparently extends to reducing mass, since J'onn has successfully passed himself off as a cat that was picked up and handled as a cat.
The canonical explanation for J'onn's multiple identities is that he is intensely curious about humans and over 50 years on the planet has been trying to experience as many human things as possible. Recent canon has revealed that most of J'onn's identities were tributes of a sort, continuations of lives of people he had met who had died prematurely.
A few of J'onn's identities are pure invention on his part, e.g. the Bronze Wraith in DC canon and Alana Jones in JV continuity. These identities have constructed lives and histories and are almost characters in their own rights. J'onn also has a variety of disguises, forms he assumes for a particular occasion or event. He has on occasion impersonated members of the Justice League, at least once impersonated Director Bones of the DEO and has an infinite variety of made up forms that he can tailor to an occasion.
How can he keep all his forms straight?
The best answer to this came in an issue of Action Comics (#774) when writer Joe Kelly introduced the idea of the Mind Mansion. J'onn's mind is so highly organized that he can effectively keep separate "rooms" in his head which each contain all the information about a given identity, from shoe size to allergies to where that identity was last Tuesday.
Partial listing of J'onn's identities
DC canon
Martian Manhunter (listed as an identity because, well, it is. J'onn also has a trueform, but it's private)
John Jones, Denver PI and former police officer
Goldie Johnston, Chicago tabloid reporter for *The World Register* (MM #26)
Yuchiro Takata, Japanese businessman, owner of New Concept Industries (MM #2, #17 - this identity was one of the ones exposed by the DEO and supposedly abandoned by J'onn. We found it too useful, so we have parted with canon on this point - this identity remains intact in the J'onnverse)
Bio Armor Jade Warrior, Japanese superhero (MM #2, #17, exposed by the DEO)
Hino Rei, Tokyo financial reporter (JLA #27, an early example of J'onn and Bruce playing the identity game)
Tomasso, Venetian cat (MM #17, killed in MM #31)

Paolo, street kid in Rio de Janeiro (MM #17, exposed by the DEO, killed in MM #31)
The Big Doof (MM #3)
The Bronze Wraith, member of the Justice Experience, served with Cameron Chase's father, the Acrobat (MM #17 and elsewhere)
Marco Xavier, early "playboy" identity (House of Mystery #160) "While undertaking this little chore on behalf of the Feds, J'onn inadvertently causes the death (!!!) of one of Faceless' top lieutenants: one "Marco Xavier," by name. Operating, perhaps, under a sense of guilt-spurred obligation (as well as that galaxy-renowned "thriftiness" which characterizes the Martian peoples, as a whole), J'onn promptly utilized his shape-shifting abilities to assume the exact likeness of the deceased Xavier, and infiltrate V.U.L.T.U.R.E. from within -- becoming, in essence, an espionage "counter-spy." (information from "Slow J'onn J'onzz" site.
Isobel de la Rosa, novelist in Montevideo (MM #10, killed during DC One Million)
John Johnstone, farmhand hired by the Kents during Clark's youth (MM #20, Action Comics #774)
