The Beyond Suit and Bruce's training is at least in part a tribute to Dick Grayson (as Nightwing).Don't know if this has been noticed, but check the design of the suit. Very similar to the Nightwing outfit. It's been shown that Bruce and Dick never reconciled, and its understandable if Bruce considers that a failure and is trying to make up for it by training Terry. Terry himself shares a lot with Dick (and other teen superheroes) with his attitude and sense of humor (we are shown that he's fundamentally different from Bruce in that he likes to talk )), except he's still fairly dark and serious (like Nightwing, compared to Robin). It can't be definitively known if Bruce's training would have had any effect on this, but its not too much of a stretch to think that Bruce acknowledge's some of Dicks better points (he is kind of a young Ace in the DCU) and try to instill those into Terry.
Nightwing was horribly injured.That's why he quit.
Nightwing is still operating.Why would Barbara tell Terry to go looking for someone who doesn't exist anymore? Dick simply changed his costume to keep up with the times, and Bruce just put the old one on display because he likes to keep things. It's not like Nightwing was identified solely with Batman; he's a fairly well known and respected superhero in his own right, and in the mainstream comics he's pretty much considered the linchpin that holds the whole damn mess together. There isn't a single superhero that wouldn't answer his call or bow to his experience, and yes, that includes Superman and Batman.
The chair was evilIt's obvious.
Aquagirl is Arthur Jr.'s daughterThe Aquaman seen in the picture in "The Call" has his old look, rather than the new one he got fortysomething years earlier. Also, he had a son back then. Do you really think he would have two kids with an age difference of a few decades? Obviously, the Aquaman seen in "The Call" was the new Aquaman, aka the old one's son, Arthur Jr, aka the guy whose dad cut his own hand off when the evil uncle nearly had him killed. Retcons apply to animated adaptations of comic books, too.
Bruce has a liver diseaseHis eyes look jaundiced. That generally means liver disease (such as Hepatitis, liver failure, etc.).
Mad Stan was originally part of The System.More specifically, he was the Chief of the Army. After being fired by the Vice President for nearly starting a war with Mars, he became disillusioned with the establishment and its incompetent leaders and made them his new enemy. This is the only thing that changed about him.
Terry's younger brother will be RobinIt's bound to happen sooner or later. He will be inspired by his older brother, Terry, to the point that he might end up wanting to be a superhero himself and assist him.
Max will be either Robin or OracleShe already helps out sometimes with the research part, which makes her fit the Oracle role. On the other hand, if she ever gets a strength-enhancing suit like Terry she could conceivably become Robin.
Superman knows the truth about Terry being Bruce's biological son
Ivy is the father of Harley's children.Look at the technology in the DCAU.
The Creeper is the father of Harley's children.Inspired by the above WMG and a never-written fanfic by this troper, look at the facts. The only two people in the DCAU that Harley has sparks with are Pamela and Jack. After working as the Joker's henchgirl for so many years, it's obvious she wasn't going to be able to ever have a normal relationship. Perhaps she just so happened to run into Jack on a blind date or in his alternate persona, Creeper still recognized her scent. She decides that a guy whose similar enough to her last beau without all the abusive qualities is a pretty nice deal and they eventually get married. Thus, it also explains the Dee-Dees offbeat personalities, since some of those toxins and chemicals probably messed up the DNA down the line.
Tim Drake is the father of Harley's grandchildren.
Splicer TechnologyStarted off from the thing developed in On Leathery Wings that turned an unfortunate scientist into a bat like creature. It has been refined to work for any animal.
The new BatSuit was made for or by BatwomanAm I the only one who noticed that the bat symbol for Batwoman and Terry are the same? Both share a similar color theme, mostly black with a few splashes of red.
Who is Curare?Well, let's take a gander. Best assassin in the League of Assassins, female, never see her face - could she be an alternate universe Cassandra Cain?
Ghoul is, in some way, related to Jonathan Crane, the Scarecrow.Take a look at him. He's pretty lanky and he clearly modelled his costume after him.
Ghoul is Carter Wilson AKA Terminal from ''Hidden Agenda''
General Norman from "Heroes" is related to General Wade Eiling.They both hate super-powered humans and costumed vigilantes. Norman could be Eiling's (illegitimate) son. Or even his nephew who respects him and joins the army in his honor.
Bonk is Bane's grandson.This is just speculation but I'm just wondering how he was able to match the Batsuit's strength...personally I think it's because Bane was his grandfather.
Grandma Harley is not Harley Quinn.They just happen to have the same name.
Bruce (of the main timeline unabused by Chronos) did remember traveling into the future by the time Batman Beyond took place.And more importantly, he remembered meeting Terry McGinnis and learning he would take up his mantle as Batman. When the two finally met when they were chronologically supposed to, Bruce decided to wait and see how events unfolded. And then Terry stole his batsuit to go avenge his father. In all honestly, he really was going to let Terry get his way and take care of business in the end. He just wanted to make sure Terry learned his lesson about not running off with old Bruce's things behind his back.
The batarangs Terry uses were derived from Rocky Ballantine's programmable metal.The metal is stored in liquid form in the Batsuit until the wearer performs a specific hand motion, then the metal comes out of the wrist in a pre-programmed form. It can even change color to red and black.
Mad Stan is the son of Lock-Up.This page pointed this out!
Barbara Gordon becomes Oracle.After she retires from her job as police commissioner, she becomes Oracle.
Tamara is related to Ace(Ace the girl, not Bruce's dog.) They are visually similar. Both have black hair, spooky eyes, psychic powers of illusion, and are both pretty powerful. Ace is obviously more powerful, but she went through the Training from Hell with Cadmus, who experimented on her to enhance her power. Tamara couldn't be a direct descendant since Ace died young, but (depending on whether Ace's parents ever recovered from their catatonia and had more children) she could be a niece or a cousin.
The T's were originally founded by Mister TerrificTheir face... thingies look really similar to the T-Mask. My theory is that Mister Terrific, getting old, realised he couldn't carry on as a vigilante (just like Batman), but decided to recruit a bunch of people who could. This might have worked for a bit, but eventually, Mister Terrific died, and the gang went off the rails. This is the source of their rivalry with the Jokerz - it began as genuine crimefighting but degenerated into pettiness. This may also be part of the reason Bruce was so leery to let Terry on as Batman.
The villain of the Batman 75 shortIs Bat-mite. He's never been officially introduced into the DCAU, he's one of the only beings with enough inter-dimensional knowledge to accurately create alternate-reality versions of Batman, and as Batman's biggest fan, would probably love to see how this version stacks up against some of the others. Either him or his son, Bat-mite Beyond.
Bruce named Ace after AceThat is, he named the dog after the member of the Royal Flush Gang. Sitting with her as she died was a major moment in his life.
