Yu-Gi-Oh! GX episode 36: "Duel Distractions, Part 1"
|Video game debut|
After Tania defeats Bastion, Bass chases the others out of the coliseum so that she and Bastion can begin their "honeymoon".
Although Tania reappears while Jaden and his friends are searching for Jesse Anderson in an alternate dimension (where all Duel monsters are made living and real), Bass is not shown to be with her at the time. However, it is revealed in one of Tania's flashbacks that he, too, entered a different dimension along with Tania (thought not necessarily the same one).
