Nobody has a clue as to why it affects metas that haven't much in common, while not affecting in the least others like Supergirl (the Matrix/Linda Lee version). The Dark Knight notices that the one thing all the affected metas had in common was to belong to the same universe, meaning that the wave was tied specifically to this reality, and correctly deduces that Supergirl isn't from this universe (Matrix, in fact, came from a pocket universe's krypton created by the Time Trapper) and point this out as the reason why she is immune to what's happening (Genesis #1).

The Kingdom: Planet Krypton #1 & The Kingdom #2

Called by Booster Gold to investigate nocturnal ghost apparitions in his "Planet Krypton" super-hero themed restaurant, Batman finds out that they are sort of echoes of other similar but divergent realities, caused by a group of Titans from the future (whom Bats detect and spot) weakening the barriers between realities with their presence & activity. Later, Bats shows he also deduced that the unfamiliar artifacts he found in Planet Krypton were, in reality, an arsenal, to be used against the mad uberpowerful Gog

A magical shields appears out of nowhere and cuts even the most powerful heroes (save Wonder Woman who is teleported inside the shield likely by Athena) off Washington meanwhile leaving Batman and the attacking amazons in there. Despite having witnessed Circe being killed right in front of her (Wonder Woman), Bruce correctly deduces that the goddess wasn't really dead and the shield was her doing (Amazons Attack #5)

Batman deduces that the people not mentioned or shown in Destiny's book (and to whom Destiny of the Endless wants to give said book) are the Challengers Of The Unknown, and works with Adam Strange to bring them on Rann, thus being instrumental in saving the universe and the future from the Luck Lords (Brave and the Bold #6)

In what is probably his first meeting with the Legion Of Superheroes, Batman deduces where/when a time-travelling Lex Luthor clone from the future (who attacked the Legion and Superman earlier) would strike next outsmarting Brainaic 5 in the process despite his 12th level intellect (Superman Batman #75)


DC VS Masters Of The Universe

He-Man, Teela, Evelyn and Queen Marlena (He-Man's mother) are in the DC Universe to search for Skeletor and, helped by John Constantine, arrive to the Bat-Cave to enlist Batman, whom Marlena defines Earth's best detective.

Bats, who has just escaped from Skeletor's grasp (unlike his JLA team-mates), waste no time in proving the Queen right. In fact, when he and the Masters Of The Universe are attacked by the mind-controlled JLA and He-Man appears to be forced to kill Superman, he is the only one of the Leaguers (who seem to have been freed by the mind control but can't remember Skeletor) to keep a cool head, trying to reason with them and not following them in their hunt for H-Man & co (who have been teleported away by Evelyn).

Then, while most of the DC heroic community is busy hunting He-Man's Group and confronting another team of Masters of the Universe who are searching for He-Man and co, Batman figures out that Superman wasn't killed at all and understands that Skeletor used that tactic to keep all the heroes busy while he steals Earth's magic

His deductions are, of course, proven to be accurate, since Superman is imprisoned inside Orko, Skeletor's dark master

Knightquest: The Search

1 - Deduces Gipsy's presence in the hotel room despite she was concealed (he aknowledges that he was helped by the fact he expected her to be around, though)(JLA Task Force #5)

2 - Recognizes an enviromental activist as the english vigilante Hood he met earlier by the way he moves (Batman is disguised as Sir Hemingford Gray)(Shadow of the Bat #22)

Putting all the pieces together, he deduces that David Cain framed Bruce Wayne for the murder of Vesper Fairchild plus figured out the identity of the real mastermind behind it all (Batman #605)

JLA: Classified #16-17 - The Hypothetical Woman

1 - when General Tuzik, a dictator deposed by the JLA, unleashes a sort of plaugue in the city of Three Sisters (Oregon) that turn its population (mostly its young people)into zombie-like state in order to draw the JLA there, Flash is infected. GL John Stewart doesn't manage to find any sign of any known plague in the city. Batman deduces the real nature of the "plague" and why a middle aged man seemed to not be affected by it

2 - since Santa Prisca Prime Minister didn't seriously contribute to Tuzik's war against the JLA and didn't want to provide money to finance it, the general uses weapons provided by Quraq to attack Santa Prisca, causing its people and the animals mental seizures. When the League arrives on the scene, they are affected, as well. Batman quickly deduces that the weapons used to attack them and the city had something to do with the Key:

After J'onn, helped by GL, came in contact with the Starros through one of their victims in order to gather info on whom is behind the recent attacks on the JLA, Batman uses a clue provided by J'onn (it's the "General" who's controlling the Starros) to deduce that general Tuzik was the one responsible for what happened (JLA: Classified #19)

JLA 18-19

When the JLA are facing a probability havok across the world that was unleashed by Julian September's machine and, among other things, caused JLAers to disappear, the team look up to Batman to figure things out. Bats is proven wrong in his assumption that no more disapperances will happen by disappearing himself (and, later, by the disappearnce of J'onn) and, in the end, the day is saved mostly thanks to the Atom and J'onn. But the Dark Knight's other deductions are proven to be correct and, specifically the comments about seven being a message and the team rooster remaining to seven, are instrumental in the disappearing martian understanding that he would have been replaced by the Atom and telling the League to brief the size-reducing hero on the situation upon his arrival, thus greatly helping in setting things right.

Cosmic Odyssey

A group of heroes including Batman is summoned to New Genesis by Highfather and Darkseid, the latter revealing that 4 aspects of the Anti-life entity are loose on this universe and, if they manage to destroy 4 key solar systems of the Milky Way, the whole galaxy will collapse. This would cause the Anti life entity to enter wholly our universe, which would ultimately results in its and the universe's destruction. So, the heroes are enlisted to stop the aspects. Batman and the New god Forager are assigned to protect Earth and its solar system. The Dark Knight's deductive skills prove to be a valuable asset, since Bats first uncover what the aspect is going to use to do his deed

Then he finds out the aspect's whereabouts

Finally, he deduces just whom the aspect is possessing

Batman RIP & Final Crisis

Batman #681

It's revealed that the Dark Knight deduced a long time ago that Jezebel Jet (his most recent girlfriend) was a member of the Black Glove (a "club" that has been planning the Dark Knight's demise for years) and has been fooling her ever since

Final Crisis #2-3

Investigating the death of Orion of the New Gods, Batman figures out that he was shot by a time travelling bullet, as later confirmed by Jay Garrick and Wally West (the 2 Flash witnessing the event happening and Barry Allen Flash trying to prevent it)

Batman #682-683

Shortly after the events of "Batman: R.I.P.", following his kidnapping and imprisonement by a Granny Godness-possessed Alpha Lanterns & fellow evil gods of Apokolis (see Final Crisis #2), Batman is enveloped by the telephatic parasite called Lump. The parasite, who also hides in Batman's memories disguised as Alfred (the Dark Knight's "oldest ally") while physically taking genetic material from him, is triggering Bruce's recollections in order to ultimately duplicate them to form a mindless army (created from Batman's DNA) as driven and as good as Bats himself

During the trip down memory lane, it's revealed that Batman had studied Joker and deduced his pathology a long time ago, when Dick just got into the Nightwing costume (see Batman #663 to have confirmation of Bruce's theory)

Then, Bats guess that the Alfred he is talking to isn't really Alfred, thus nearly spotting the Lump and forcing Batman's keepers to stimulate the creation of memories of an alternate life where the Dark Knight never was, in order to distract Bruce and keep taking what they need

A stratagem that ultimately fails, since the Caped Crusader's memories shift as if he was aware of his jailers' presence and he tries to break free, an attempt that isn't successful only because the evil gods have the scenery interrupted and Bats to continue re-visiting his memories

Unfortunately for them, Batman has now understood that he is "like a book being read" and is dead sure the Alfred he is talking to isn't the real Alfred, thus prompting a confrontation between Bats and Lump

By the end of which, after Lump is shot (sort of) by his "employers", Bats figures out he is unconscious and restrained somewhere and enlists Lump's help to awake.
