Spear Cretin, known as Dark Familiar in the Japanese version, is a character version of the "Spear Cretin" card, who appears in the alternate dimension in Yu-Gi-Oh! GX.


Spear Cretin acts as a spy for Guardian Baou and was spying on Jaden Yuki and his remaining friends. It reports to Baou that Jaden is unwilling to use "Polymerization" in any Duels due to the dark memories of The Supreme King haunting him. Baou, happy with that news, decides it is time for him to beat Jaden and gain Jaden's original position as the Supreme King as well as become ruler of the current dimension.[1]
