its 'brothers', forced Sersi to send them after the six other Gems. The Black Knight and Ultraforce failed to wrest the Gems from Loki's control. Sersi used her remaining free will to return them to their base. Now completely, under the Ego Gem's control, Sersi became aware of the Grandmaster's presence in the Ultraverse. This Elder of the Universe had journeyed to the Ultraverse in an attempt to obtain the Mind gem. Realizing the opportunity, the Ego Gem forced the Grandmaster to do its bidding as well. The Grandmaster approached Loki, and proposed a game. If he won, the Grandmaster would be given the Mind Gem. If Loki won, he would be told the location of the Ego Gem. The game was called Worlds and Warriors, a simplified version of an Earth card game. Instead of cards, however, actual heroes would be used. The Grandmaster had chosen the Avengers, while Loki had chosen Ultraforce. Members of each team were pitted against members of the other. The Avengers, for their part, were told it was to stop Loki, and to save the Black Knight, while the members of Ultraforce were told that the Avengers were part of an invading force. The various battles ended in stalemates, and Loki, used claimed victory. The Grandmaster (slave to the Ego Gem's will), revealed Sersi to Loki. She launched herself at him, and was able to separate him from the Gems before he could act. At this time, the Ego Gem released Sersi from its power. Reuniting with the six other Gems, they were rendered entirely sentient, anthropomorphizing into a cosmic being calling itself Nemesis. Nemesis wanted to create a new world, and (joining elements from both the Avengers and Ultraforce's worlds) created an amalgam universe. There were too many conflicting elements though, and when Topaz of the Ultraverse made physical contact with Loki, elements from two wildly different continua, the structure snapped. In her panic, Nemesis teleported to the Ultra's Earth, and intended to continue creating there, even if it meant the destruction of the world that was there already. The six other Gems were resisting her though, for the being called Nemesis lacked the controlling influence that was needed to unite them. The Avengers and Ultraforce joined forces to stop her. Creating a diversion, they attacked her together, allowing the Black Knight to get close enough to separate the Gems once more. In
