War of Kings is a Marvel ComicsBat Family Crossover of the year 2009. It follows events of the Secret Invasion: Inhumans, X-Men: Rise And Fall of the Shi'Ar Empire and X-Men: Emperor Vulcan storylines, and plot elements in various other titles, like Nova, Guardians of the Galaxy or Annihilation: Conquest. Darkhawk gets involved as well.After their home on the Moon was attacked by Skrulls during the Secret Invasion event, The Inhumans chose to leave for space, where they not only had revenge on the green shapeshifters, but also attacked their own creators - the Kree Empire. With the Kree's defeat, the Kree leader, Ronan, gives up his position, announcing Black Bolt as the new king of the Empire. This doesn't escape the sight of another cosmic monarch - Vulcan, Emperor of the Shi'Ar - who quickly finds an excuse to start a war between the two space nations. So big a conflict cannot avoid involving third parties; the Guardians of the Galaxy, the Nova Corps and Blaastar's army from the Negative Zone are all brought into the conflict.Follwing this event, Marvel put out a series of comics under the title Realm of Kings, which served as a bridge to their next event, The Thanos Imperative.
War of Kings provides examples of:
Ancient Conspiracy: The Fraternity of Raptors. Black Bolt destroying the Skrull fleet reactivates them.
An Arm and a Leg: Gorgon loses a leg to the Shi'ar Imperial Guard, but it's quickly re-attached. Ch'od loses a hand to a Portal Cut, but gets a new one pretty quickly.
Anyone Can Die: Lilandra, Black Bolt, Vulcan, a whole Nova cohort and a good number of Guardians of the Galaxy regular. Black Bolt gets better, and the Guardians turn out okay in the end.
Bad Future: This event caused at least one. Adam Warlock's attempts to fix the Fault cause him to become the Magus, which starts overriding every other possible future as well.
Bittersweet Ending: Vulcan and Black Bolt battle with Black Bolt coming out victorious. Crystal disables the T-Bomb from its original intent and seems to convince Black Bolt the plan was flawed. But before she, Lockjaw and Black Bolt can escape Vulcan revives and Black Bolt is forced to stay to battle him. During the fight the bomb is set off by Black Bolt's voice, leaving both kings lost and a gaping hole in the fabric of the universe which is a tunnel to something... bad. Not to mention the Fraternity of Raptors still lurking in the shadows.
A subtle theme that Vulcan eventually makes explicit is that the war is making Black Blot much less of a Foil to Vulcan.
From a Single Cell: Vulcan is killed by a point-blank blast of Black Bolt's voice. A few pages later he gets up again.
From Bad to Worse: Things were already bad after the Annihilation War and the Phalanx Conquest. Then the Shi'ar and the Kree, the last two big empires left, go to war, endangering reality itself, which is on the brink of collapse. And then Lilandra is killed, throwing the Shi'ar empire into turmoil. And then, in the last issue, Black Bolt causes the T-bomb to go off, opening the fault and quickly causing the creation of the Magus, who is the herald for a far worse threat.
Heroic Sacrifice: The Skrull possessed by Talon killed himself in order to get rid of him. Sadly, it doesn't stop him from coming back.
Black Bolt's original intention for the T-bomb may be interpreted as one of these.
Human Aliens: Oh God, where to start. The Shi'Ar look like humans with weird hair; the Kree, and Strontians (Gladiator's species), look like humans but with different skin color. Phyla, Smasher, a few other members of the Imperial Guard and at least one Nova Corps member look like humans, or have very small differences.
Jerkass: Medusa spends most of her time being snide, sarcastic and demeaning towards everyone else. She also shows some signs of jealousy when Crystal is more liked by the common Kree.
Mêlée à Trois: Kree Empire vs Shiar Empire with the Nova Corps, Star Jammers and Guardians of the Galaxy caught in the middle trying to stop it but usually just getting into fights.
Mythology Gag: Blackbolt's plan to transform people into Inhumans is the same one he used on a smaller scale in Earth X and would later be used again in Comicbook/Infinity.
Negative Space Wedgie: Several of these already existed due to the events of Annihilation, and the war is making them worse. It's part of the reason the Guardians of the Galaxy get involved. The very end of the event causes a truly massive one, the Fault, which spreads over several light-years.
Nice Job Breaking It, Hero: The Inhuman attack on the Skrulls frees Talon from his interdimensional prison, which eventually causes the death of Lilandra.
Also, the detonation of the T-bomb breaks the universe, and is retroactively responsible for the return of the Magus.
