Question: How didn't Syndrome already know that Bob or Mr. incredible married Elastigirl? There is a computer with all the information about superheroes, so he would surely know this. I know that her location was unknown, but they were married before supers were made illegal and Incrediboy (his alias 15 years prior) was his biggest fan.
Question: What work does Mr Incredible actually do for Mirage after he's fired from Insuricare? There's the montage of him working out and getting a new car, supposedly from earning cash working for Mirage. But what was he actually doing for her? We never see it. He didn't fight any Omnidroids.
Answer: My impression was that he wasn't working at all. He got a large payment from them for fighting the first omnidroid. After that he simply pretended to go to work, when in fact he was spending his time getting in shape (and buying things).
Question: How did Syndrome's plan to kill the Supers work practically? He sent them to the island to fight the Omnidroids, and they were either killed or defeated the robot. If they defeated the robot, he used that to improve his next model. But how did he get the Supers that defeated the Omnidroid to return to the island and fight another model? Can't use the same story again, that'd be suspicious.
Answer: Same way they got Mr. Incredible to come back, give them small missions to do (employ them basically) until the new droid is finished for testing and then lure them back for a supposed new mission and surprise them.
Question: A few questions about this movie. Firstly, Syndrome's ultimate plan was first testing his prototypes on other supers, using the next had the last been defeated, and all leading up to the final face off with Mr. Incredible. What would Syndrome had done had Mr. Incredible denied the opportunity from Mirage of coming to the island to do the hero work as devised and everything he planned had been spoiled? Secondly, when Mr. Incredible was captured and held hostage in the round electric type of cell, did Syndrome plan for him to just hang there until he died? Thirdly, what made Mirage suddenly have a change of heart after all the working she's done with Syndrome and killing off supers in the past?
Answer: Syndrome's plan worked because even though the superheroes were retired a lot of them missed the old days and wanted to do real superhero work. This opportunity lured a lot of them to the island, including Mr. Incredible. If he hadn't gone there Syndrome would have found others. He kept Mr. Incredible locked up there until his plans of sending the robot were executed. Afterwards he probably would have killed him, perhaps by turning the robot loose on him again but this time in public. Mirage got second doubts when she realised Syndrome didn't care about her or the lives of innocents, I'm guessing a lot of information was kept from her and she simply thought Syndrome was after power and not petty revenge on superheroes.
I'm a little confused about the second and third answers. We saw that Syndrome was trying to destroy the robot while mimicking it (really, using his remote) while he meanwhile had the Incredibles held hostage at his island. How would he have sent Mr. Incredible to the public to be killed by the robot if it were destroyed? Also, if Mirage thought the superhero revenge on Mr. Incredible was minor and the other supers he was killing were innocent, why did she decide to be his assistant and help him in the first place?
I'm sure his first encounter with the robot was just for show, letting the people think he beat it, without actually damaging it. The point was that the robot could not be defeated by any superhero and then everybody would flock to him and he could sell his inventions to make everybody "super" so superheroes will not be necessary anymore. It's somewhere along the lines of that anyway, I've never actually known what his actual plan was. The point was to make an unbeatable robot that only he could defeat by cheating, then sell his inventions to everybody. That I'm sure of. How he was going to take his revenge on supes to the next stage I don't know. Mirage wasn't innocent, she knew supes were being killed by the robot but she thought he did it for power. She also started to like Mr. Incredible I think. Once she realised he didn't care about her or literally anyone else she decided to betray him. Maybe she found out what real power is, and he didn't have it.
Question: What are the symbols behind Mr Incredible's head at Edna Mode's house? What do they mean?
Answer: If you mean the mural in the background as they enter the house, it's a depiction of Perseus fighting medusa. There are several ancient greek symbols visible also. Probably depicting names.
Answer: They got married as their secret identities, only their fellow superheroes knew it was Mr. Incredible and Elastigirl that got married, no fans. Syndrome also already wasn't a fan of him anymore and stopped following him.

What about the message that Mirage sent to Bob Parr? In it, she calls him Mr. Incredible and then says that his secret is safe. Since Mirage knows that Bob is Mr. Incredible and works for Syndrome, wouldn't that mean he knows Bob and Mr. Incredible are the same guy too?
Sure, Mirage personally recognized Mr. Incredible in the car with Frozone, who they were tracking. But they didn't make the connection yet that his wife is a super as well. In time they might have, but the focus was on Mr. Incredible right away, since that was Syndrome's number 1 super to find and test the robot on.
