!!''ComicBook/WhatIf'' the comic book
* CompleteMonster:
** ''What If? Age of Ultron'': As in [[ComicBook/AgeOfUltron canon]], ComicBook/{{Ultron}} is a [[AIIsACrapshoot genocidal]] and [[RoboticPsychopath psychopathic]] machine obsessed with nothing less than [[OmnicidalManiac the total annihilation of all organic life]]. Created by Hank Pym to be a protector of the Earth, Ultron quickly grew [[AGodAmI a god complex]] and proceeded to [[KillAllHumans slaughter every man, woman, and child]] on Earth within a month, after which he drew out any rebels' defeats, taking sick glee in watching their hope slowly die and seeing them turn on one another. After successfully killing every living thing on the planet, Ultron allows his "father" Hank Pym to live, solely so that for the decades to come, he can [[ColdBloodedTorture brutally torture]] him, wipe his memory of the torture, then start all over again to [[MindRape slowly break his human spirit]], all because he "can". Later learning of the multiverse, Ultron organizes full-scale wars on 4 alternate dimensions nearby , massacring everything in his path on 4 separate Earths. Ultron's final plan is to continue spreading his influence across every reality, hoping to eventually kill every living thing in the multiverse, uncaring that this plan could very well destroy reality itself. Continuing his streak of misanthropy and sadism displayed in many of his iterations, this Ultron sticks out as one of his most depraved variations yet.
** ''What If... Captain America Fought in the Civil War?'': Colonel Buck "Bucky" Barnes is the seemingly kind commander of the Union regiment known as the "Redlegs", however his seemingly noble appearance is quickly shown to nothing but a mask. In truth, Barnes is a cruel sociopath who uses his position to [[SociopathicSoldier organize the massacre of every man, woman, and child]] in defenseless towns in Confederacy territory, while claiming that said towns are Confederate hideouts, so as to loot all the money and treasure the townsfolk possess. When a lone soldier, Steve Rogers, refuses to kill three children on Barnes's orders, Barnes wastes no time in trying to kill the man, and, later learning that Rogers has taken up residence at a nearby Union base, Barnes orders everyone in the base slaughtered after his face is turned by magic into a white skull of death to represent his true personality. Even after his defeat, Barnes later escapes and reforms the UsefulNotes/KuKluxKlan into a [[PoliticallyIncorrectVillain white supremacist terrorist group]] that, even decades later, continues Barnes's mass murdering agenda, regularly targeting highly-populated public buildings and dueling with any heroes in their way. Barnes, later known as White Skull, was a twisted composition of the canon Marvel characters James ComicBook/BuckyBarnes and the ComicBook/RedSkull, and obviously took far more personality cues from the latter, as evidenced by his homicidal greed and sadism.
** ''What If...Daredevil Lived in Feudal Japan?'': The Giant Shogun, an adaptation of the canon character ComicBook/TheKingpin, is the [[FatBastard massive]], hedonistic boss of TheYakuza who simultaneously runs Japan through manipulating the Emperor. The Shogun regularly orders assassinations, forces innocents into slavery, and often blackmails warriors into doing his bidding, notably [[EyeScream blinding]] the [[WouldHurtAChild infant son]] of Old Devil to force him into servitude in exchange for the cure for the blindness. Forcing Old Devil to massacre an entire ship of Americans so as to allow one of his spies to steal weapons plans, the Shogun [[NeckSnap snaps his spy's neck]] when [[YouHaveFailedMe he fails]], has the man's wife murdered, then begins transforming their child daughter Elektra into his personal killing machine, tormenting and raping her along the way. Years after murdering Old Devil, taunting him about the fact that there was never a cure for his son, Masahiro's, blindness, the Shogun poisons his [[TheDragon Dragon]] Stick to prevent any power struggles, murders one of his own men to steal his horse when he comes under attack, and leaves the Emperor of Japan to die to cover his escape. When confronted by a now-grown Elektra and Masahiro, the Shogun orders them both be incapacitated by a marksman, wanting to draw their deaths out painfully in public later as a show of what happens to those who defy him. A sadistic, greedy scumbag who cares for no one but himself, the Giant Shogun was nowhere close to his counterpart the Kingpin in nobility, honor, or grace, substituting these for depravity and malice tenfold.
* HilariousInHindsight: Plenty of scenarios in the comic actually happened as time went on - Spider-Man joined the Fantastic Four in the Hickman run, Hulk became a barbarian in the ''PlanetHulk'' series, ComicBookTime means that Captain America was probably revived decades after both iterations of "What if Cap were revived today?", Elektra's survival has been retconned in...
** The joke scenario in #34, "What if Every Avenger Remained an Avenger", depicts the silliness of an Avengers team with dozens of members. Ever since ''ComicBook/CivilWar'', that lineup has looked downright sparse.
** HarsherInHindsight/ FunnyAneurysmMoment: "What if Spiderman Had Not Married Mary Jane" became more like a canon after the release of [[http://tvtropes.org/pmwiki/pmwiki.php/ComicBook/OneMoreDay?from=Main.OneMoreDay "One More Day"]] in 2007.
** What if General Ross had become The Hulk? [[ComicBook/RedHulk I wonder if indeed.]]
** What if Jane Foster Had Found the Hammer of Thor? [[ComicBook/{{Thor 2014}} That'll never catch on.]]
** In "What if J. Jonah Jameson adopted Spider-Man?" (v2 #82), Flash Thompson becomes the Scorpion. Years later in canon, he'd claim another power set that once belonged to Mac Gargan: Venom.
** #46 of the second series, "What If Cable Destroyed the X-Men?", leans toward HarsherInHindsight. The book opens with Cable killing Professor Xavier, Jean Grey, and Cyclops. This was released just a little less than a year before it was revealed that Cyclops was Cable's father.
