"Alexis vs. David!!", known as "Asuka vs. Rabb!!" in the Japanese version, is the twenty-fourth chapter of the Yu-Gi-Oh! GX manga. It was first printed in Japanese in V Jump magazine and in English in Shonen Jump magazine. Both of which were printed in volume 3 of the Yu-Gi-Oh! GX graphic novels afterwards.
Jaden Yuki is relieved at Reggie MacKenzie's defeat, as he won't need to face her in a Shadow Game, but realizes that he still may end up dueling David Rabb. David is surprised that Reggie lost, and she responds that everyone has a bad day sometimes. She warns him to be careful during his duel with Alexis Rhodes, and to work hard to get his payback. He asks what she means, and she simply says he couldn't afford to lose to "his little sister" as well, implying the Atticus Rhodes had defeated David in the past.
David attacks with "Saturn" and Alexis activates her face-down "Blizzard Wall", switching "Cold Enchanter" to Defense Position. David activates the Quick-Play Spell Card "Aftershock", which will grant his Machine-Types the piercing ability for the remainder of the turn. Alexis takes 1600 damage and "Cold Enchanter" is destroyed. This lets her activate the other effect of "Blizzard Wall" - "Saturn" now gains an Ice Counter. Alexis wasn't expecting such a powerful monster so early on, but has "Absolute Zero Barrier" in her hand, so she's confident she can stall on her next few turns. Alexis' other Set card, "Doble Passe" appears to have activated on its own, and David explains that he played "Forced Activation", which activated her card via its effect. He activates "Ignition", which changes the effect of "Doble Passe" "destroy one monster on the field. "Saturn" is destroyed, and its effect activates, causing both players to take damage equal to its ATK Alexis takes 2800 damage, reducing her to zero Life Points, but David survives with 1200. Thus, David has performed a One Turn Kill. Alexis is shocked and falls to her knees, while David hopes that when he and Jaden Duel, he'll be able to take both "Winged Kuriboh" and "Elemental Hero Terra Firma" from him.
