How to Easily Beat Act 6 Grandmaster Final Boss

In the Story

Becoming the Grandmaster

Three billion years before the current iteration of the Contest, En Dwi Gast and his brother Taneleer Tivan discovered the Battlerealm, then known as the Nexus Realm. Years later, they explored the Nexus Realm along with Taneleer's daughter Carina. Carina ventured outside their spaceship as the trio were caught in an unexpected energy explosion, trapping En Dwi under a rock and shattering Carina into a billion fragments. Taneleer became obsessed with collecting Carina's fragments in the hope of resurrecting her, and left En Dwi behind.

After some time En Dwi broke free of the rock, and without a spaceship began a long journey to walk out of the Battlerealm. This proved a hard task as space-time was fragmented, and En Dwi would constantly be transported years back in time, or in the wrong direction for every few steps he took. He eventually solved the puzzle and returned from the Battlerealm, and gained his obsession with playing games, accompanied with a grudge against his brother for abandoning him.

Elder's War

The Grandmaster would only return many years later, after the Rebellion against Maestro and the Cosmic Civil War, surprising the Collector as he aligned with Loki and claimed the Battlerealm for himself, instigating the Elder's War. The Grandmaster would sway many Champions to his side with false promises of freedom, and as the Collector desperately allied himself with criminals and mind controlled anyone who defied him, the Summoner was prompted to defeat him in the Galactorum, ending the Collector's reign. The Grandmaster taunted him before encasing him in a crystal prison and assuming control of the Contest.

Soon, as Grandmaster's reign spread across the Battlerealm, Champions formed uneasy alliances and were tasked with reforming the Cornerstone. The Grandmaster attempted to stop an alliance of the Summoner, Doctor Strange, Doctor Voodoo, Black Panther and Kang, among others, from doing so, and pitted them against Ultron, but the Summoner was ultimately victorious and the Grandmaster relented. Doctor Strange then reassembled the Cornerstone, revealed to be Carina but still missing the heart.

After the Collector was freed and reclaimed Carina's heart from the Sentry, he was visited by Grandmaster, who presented him with the final piece of the Cornerstone, as a gift for his niece.

Infinity War and the Tournament

During the Infinity War, the Grandmaster's contest was forced to a halt by Thanos, who drained the power of the ISO-Sphere, and he would only regain control after Thanos' defeat at the hands of the Summoner and the Avengers. In an attempt to regain the power lost during the war, the Grandmaster allied himself with the Champion, a fellow Elder of the Universe, and defeated a multitude of Champions to absorb their ISO-8. This plan was foiled by the return of Ægon, the first Champion of the Contest, who defeated the Champion and restored Carina to life.

Great Revival

As the now-revived Carina began to explore the Battlerealm, the Grandmaster intervened, wanting to see the full potential of her powers. He pitted Carina and the Summoner against a Sentinel and a Power Stone-infused Champion to test their limits. Noticing the collapse of Mister Fantastic's anomaly, he made his way to the site and realized that he, along with Doctor Doom and Silver Surfer, had summoned Galactus to consume the Battlerealm. Furious, he detained Mister Fantastic and organised a trial to judge him of his crimes, until Richards was prompted by Carina to plead guilty, and was punished to find a way to stop Galactus and to incapacitate Silver Surfer for being a Herald of Galactus.

As Carina earned the trust of more and more Champions, including the Avengers, Grandmaster's position was threatened and he attempted to sway the Summoner to his side. However, the Summoner instead fought the Grandmaster with support from Carina, the Collector, Ægon and other champions, and En Dwi's reign over the Contest was finally brought to an end. He was then imprisoned by Carina alongside his brother, freeing the Battlerealm of their constant meddling.

The Union

Grandmaster eventually regained the trust of Carina, and was assigned to overseeing organized wars between Summoner alliances. He was then further assigned with Captain Britain and Nebula to host a tournament for leadership of the mutants, between the mutant leaders Magneto, Professor X and Apocalypse, as well as Omega Sentinel in secret. With all participants swiftly defeated the Summoner, Grandmaster successfully convinced the mutant leaders to work together against outside threats instead.
