It doesn't matter if it's "canon," it's that it's in the game. That's like saying an episode of Dragon Ball Z where Vegeta gets buttraped by Piccolo would be okay because it's just filler and not canon. Or to use a comic example, this is like when everyone was okay with Miles Morales at first, because it was only the Ultimate Universe, it wasn't really canon. Look where we are now. I suppose we shouldn't criticize garbage like I Am Not Starfire, because don't worry, it's not canon (for now).
I'm gonna be autistic and list things that originally weren't canon and became canon. Some are actually okay, some suck. I'll focus mostly on good ones because I just stopped reading once they became really bad.
>Jimmy Olsen
The closest thing Superman has to a sidekick was originally from the radio show. They try to now say that an unnamed kid who didn't really look much like him in an early issue was Jimmy, but that's bullshit. Anyway Jimmy Olsen went on to have his own comic series that had well over 100 issues, and was the original nemesis of Darkseid, the big bad of the whole DCU. Also after Superman actor George Reeves was killed, they tried to do a spinoff tv series about Jimmy Olsen, but it never got off the ground, if you'll pardon my pun.
>Kryptonite
This was only invented because the actor who played Superman on the radio show wanted to take a vacation, so they needed a storyline where Superman gets sick.
>Superman's Kryptonian name (and the names of his parents)
Kal-L, Jor-L, and Lara were all named in the Superman newspaper comic strip (separate continuity from the comic books) and a novel based on it (but which itself wouldn't have been canon to the comic strip, and definitely not the comic books).
>The Batcave
Originally from the early '40s film serial.
>Alfred coming back to life
In the '60s they killed off Alfred. But then they did the Batman TV show, and Alfred was a main character. So the comics said that actually Alfred wasn't killed when he got hit by that boulder, he just got his brain broken and he became a supervillain called The Outsider, who used his knowledge of Batman and Robin to be the most dangerous threat out there. Then Batman and Robin rescue him and fix his brain and vow never to speak of it again. Later, when Robin grows up to be Batman and a demon is pretending to be Bruce, Dick asks him to say something only the two of them would know. The demon mentions that Alfred was The Outsider. It is true, only Dick and Bruce would know that. But Dick knows that the thing he's talking to can't be Bruce, because they vowed never to speak of it again.
>Catwoman being black
Originally from the '60s tv series, where three different actresses played Catwoman and one of them was black and they just never acknowledged that she looked different each time. (Other characters like Riddler and Mr. Freeze also had different actors in different episodes, and they did play them pretty differently, but none were a whole different race.) By the '80s Catwoman was drawn as pretty ethnically ambiguous, though when push came to shove, was still white. But now she's black in the latest live action TV series and the latest live action movie. Mark my words, she's gonna be black in the comics any day now.
>the crystalline appearance of Krypton/The Fortress of Solitude.
Originally from the 1978 Superman movie. It was cool so it got put in the comics eventually.
>Superman's dad dying of a heart attack but his mom surviving into the present
Again from the 1978 movie. Canon at least for a few years in late 2000s comics. Also Superman's dad had a heart attack in the Death of Superman arc, and went to heaven, but they brought him back at the hospital or something. Clearly a reference to the movie.
>Batgirl getting crippled
The author insists he never intended her to be crippled and was told the story wouldn't even be canon. But it was very popular, so they acknowledged the shooting, said she was crippled now, and that stuck for almost 25 years. Then she was uncrippled for no reason, but the fact that she was crippled in the past is still canon.
>Robin II (Jason Todd) dying
This was established history in the alternate-future story The Dark Knight Returns. That story became perhaps the most popular Batman comic ever, so a few years later they did a story where Jason died in the present.
>Batman using a grappling hook
Originally from the 1989 movie. Hard to believe, but Batman never used a grappling hook before this.
>Damian Wayne
The originally non-canon book "Son of the Demon" involved Talia finally getting that Batman seed she wanted so badly. about 15 years later they decided it would be cool if actually this was canon, so they just said it was canon now, and now we have Damian.
>Harley Quinn
Originally from Batman: The Animated Series.
>Mr. Freeze's tragic backstory
Originally from Batman: The Animated Series.
>Dead Robin coming back to life and becoming an alter ego of The Joker (Red Hood)
People don't acknowledge this, but hear me out. DC Animated Universe Tim Drake is really Jason Todd in all but name. He's the second Robin and he's from the streets and has a temper. They just called him Tim because Tim was the current Robin in the comics at the time. In the direct to video movie, Batman Beyond: Return of the Joker, we find out that the reason Tim stopped being Robin was because he was kidnapped and tortured by Joker, in a bit that's clearly inspired by Death In The Family, where Jason died. Except here Robin lived, but retired, but way in the future it turns out he was brainwashed and genetically altered into becoming a clone of The Joker. A few years after this, DC did a story where the Robin who was tortured by The Joker (but died) came back to life and took on the identity of Red Hood, which is Joker's former identity before he became The Joker. This storyline was clearly inspired by Return of the Joker and nobody acknowledges it.
>Spider-Man's organic webbing
In the mid-2000s they tried to make the comics match with the movies. Spidey died but his corpse birthed a new body for him or something. It was all mystical and stuff. Anyway this body was the same as the old one except it had organic webbing. They got rid of it shortly after, around the time he sold his marriage to the devil. I'm not 100% sure, but I think the organic web shooters were erased here too, as if they were dependent on him being married. Note that other things that were somewhat related to his marriage, like his baby daughter, May, also got erased. May was kidnapped by the Green Goblin almost a decade earlier and Peter just kinda never got around to rescuing her, though in the future stories of the MC2 universe (meaning they weren't "canon" but could be), she was Spider-Girl. When Peter sold his marriage, she was specifically brought up, after years of being forgotten, just to say she was getting erased. But at least it got rid of the organic web shooters.
>Superman having a son in the mid-2000s
When Superman Returns came out they tried to tie into it by having Superman and Lois adopt a Kryptonian kid, so for kids picking up the comics, they'd see Superman has a kid with his powers now. But Superman Returns wasn't that popular so a while later they revealed the kid was actually General Zod's biological son, Lor-Zod, and he sacrificed himself to send Zod and his army of Kryptonians (most of whom were former good guys from the Bottled City of Kandor) to the Phantom Zone. Later, Flash changed history and now Lor-Zod loves his dad and is a villain. I guess maybe that didn't have to do with history changing, maybe he just got convinced.
>Samuel L. Jackson as Nick Fury
Originally in the Ultimate Comics, because writer Mark Millar likes making characters look like celebrities. And people liked it in that universe, and Jackson gave permission to use his likeness and wanted to play the character on screen, so he did. And people liked it because it was an alt universe anyway. Then Marvel used this as an excuse to get rid of the original Nick Fury from the main universe and replace him with his black son. So yes, we did lose the original Nick Fury.
