This story was first printed in Wonder Woman Giant #4 and #5, which were both published as part of a series sold exclusively at Walmart stores in the United States. The series formed part of a larger partnership with DC Comics which was launched in July 2018.
Synopsis - Part Nine
Wonder Woman, Sibella and Cheetah are captured and taken to a cell where they are told they must prepare to fight to the death in the arena to reduce their prison term. All three volunteer to be the first but Sibella is chosen. Meanwhile the others are also captured and taken to watch the death match.
Wonder Woman and Cheetah are chained and also forced to watch as Sibella is confronted by a brute of another prisoner to fight. But Sibella holds her own and manages to pin the fallen prisoner, preparing to kill him. But Wonder Woman manages to burst free from her chains and tells Sibella that killing is not the right path.
The aliens tell her that interference is against the rules and she must fight Sibella instead. She refuses but they reveal that they have Steve and Etta at gunpoint and so Diana has no choice but to take up arms and confront Sibella.
Synopsis - Part Ten
Sibella tells Diana that without her enhanced powers she is doomed but the Amazon Princess says she still has her skills. At first the fight seems evenly matched as each draw blood but eventually Wonder Woman’s prowess wins out and she slashes Sibella, forcing her to collapse to the ground as Diana stands over her.
The watching aliens decide enough is enough and remove the mind blocks that Sibella has had in place. She becomes a completely different person, unaware of who Diana is or what has happened and orders the Amazon and the others to be returned to the cells while she watches the video recordings of everything that has happened thus far to bring her up to speed on recent events.
Back in their cells, Wonder Woman deduces that it has been Sibella who has been playing this game all along, bringing them all together and forcing them through their various trials for sport. She decides to confront their tormentor and manages to break free. She tells the others to head for the ship while she races to the Princess’ chambers.
