Season 1

 * The nation of Orange Star in at war against the neighboring nation of Blue Moon, with Olaf as the Blue Moon Army commanding officer (CO). Olaf suddenly ordered an invasion of the Orange Star nation and is in battle with the Orange Star Army.
 * Nell, the de facto leader of the Orange Star COs, gives Andy the duty of a tactical advisor for the Orange Star Army.
 * After winning a battle against Green Earth, Andy gets mysteriously accused by Green Earth's CO, Eagle, of committing a treacherous act of aggression against Green Earth.
 * After defeating the Blue Moon troops that invaded the Orange Star country, the Orange Star Army then invade the Blue Moon country, defeating their troops. The Blue Moon COs, Olaf and Grit, are revealed to be COs who both used to work for the Orange Star Army, but switched to Blue Moon.
 * When the Orange Star Army's intention was to just pass through the other two countries, Green Earth and Yellow Comet, the countries' COs like Kanbei of Yellow Comet assume a threat of an invasion and declare battles against the Orange Star Army in their land.
 * Later on, Green Earth CO Drake tells Eagle that the Orange Star Army didn't attack Green Earth, saying that "This entire conflict has been orchestrated from the beginning."
 * Meanwhile, Yellow Comet CO Sonja and Grit try to discover the person who is really behind the attacks.
 * When Eagle meets Andy again, Eagle again accuses Andy of attacking Green Earth, to which the Orange Star COs eventually convince Eagle that it wasn't Andy who attacked Green Earth. This explains why the three nations have been declaring battles against Orange Star, as they thought Andy attacked them first.
 * When Eagle meets Sonja, Sonja also tells Eagle that Andy wasn't behind the attacks, saying it was someone else, and goes with her to see what she discovered. It is revealed that the enigmatic Black Hole Army, under the command of Sturm, is the true enemy. Using a CO doppelganger clone of Andy, Sturm stirred up war among the four countries in order to confuse, weaken, and eventually conquer them.
 * Once this is revealed, the four countries unite to drive Black Hole out of their land, the Cosmo Land, with COs automatically chosen depending on the paths the player took during the game.

Black Hole Rising

 * While the Allied Nations were still recovering from the war in Cosmo Land, the Black Hole Army had already recovered and has decided to launch a large-scale invasion on Macro Land. Along with the original Black Hole army's commanding officers (COs), four new COs were recruited, under the command of Sturm:
 * Flak: Black Hole's strongman in charge of invading Orange Star.
 * Lash: A girl genius having invented most of Black Hole's technologies, invading Blue Moon.
 * Adder: A narcissic commander in charge of invading Yellow Comet.
 * Hawke: Black Hole's second-in-command and Sturm's most trusted ally.
 * Sturm orders each Black Hole CO to invade and capture each of the four continents controlled by the four other armies from the original game:
 * Orange Star by Flak.
 * Blue Moon by Lash.
 * Yellow Comet by Adder
 * Green Earth by Hawke.
 * Lash also invented several new war weapons like the Black Cannon and the Mini Cannons that were to be put to use in this invasion. The four allied armies must now work together to drive Black Hole out of their world once and for all.
 * Once the Black Hole troops are driven from the Allied Nations' continents, their COs convene in Black Hole territory, near Black Hole's base of operations. Here they fight Sturm, the mastermind behind the invasion.
 * The final battle takes place in front of the Death Ray, a powerful new weapon guarding the entrance to a missile, which, if not subdued in time, would destroy half of Wars World.
 * The Death Ray is eventually destroyed by the COs of the Allied Nations, who manage to disarm the missile and corner Sturm.
 * In an act of desperation, Sturm attempts to blow up the base and inflict damage on Wars World by self-destructing the missile. Andy attempts to stop Sturm to no avail. However, in a surprising turn of events, Hawke, second in command to Sturm, betrays his leader by killing him with Black Storm before the self-destruct is triggered.
 * Hawke takes over as leader of Black Hole, and along with Flak, Lash, and Adder, leaves Macro Land with the few troops he has left.

Dual Strike

 * The Black Hole Army has returned under a new commander, Von Bolt. He is accompanied by his Bolt Guard: Jugger, Koal, and Kindle, along with Hawke and Lash from the original Black Hole Army.
 * Using Lash's new Black Obelisks, Von Bolt is draining Omega Land of its energy to give him eternal life, and is also starting to use this power to produce a bio-weapon named Oozium 238, a strange slime-based monster that devours anything in its path. However, Hawke notices the energy draining (which also is turning Omega Land into a desert) and questions its use.
 * After uncovering Von Bolt's plot, Hawke is betrayed and Von Bolt attempts to swarm Hawke and Lash with Oozium 238.
 * After the Allied Nations’ COs save Hawke and Lash, the COs, along with Hawke and Lash, begin to turn the tide against the Black Hole Army.
 * Both Hawke and Lash provide valuable intelligence of the Black Hole weaponry and its plans for Omega Land.
 * With this information, the Allied Nations slowly corner the Black Hole Army, leading to a battle in the middle of the Crimson Sea.
 * After destroying the last Black Obelisk, the Allied Nations proceed to the final battle where they fight Von Bolt and a giant oozium known as the Grand Bolt.
 * After destroying the Grand Bolt, Hawke destroys Von Bolt's life support chair, supposedly causing Von Bolt (and presumably Hawke) to die in the aftermath.
 * With the Black Obelisks gone, Omega Land begins returning to normal. Hawke is revealed to have stolen Von Bolt's chair and escaped, leaving Von Bolt either dead or barely alive. With the power in Von Bolt's chair Hawke revives all the land.
