- In episode 19, Para uses this card during his Tag Duel with Dox against Yami Yugi and Joey Wheeler. Para created this monster by using "Polymerization" to merge "Shadow Ghoul" with "Labyrinth Wall". This card then attacks and destroys Yugi's "Beaver Warrior" by moving through the walls of the maze and attacking where Yugi's monster was located. Later this card attacks Yugi's "Celtic Guardian", but Joey activates "Kunai with Chain" to increase "Axe Raider" and "Celtic Guardian's" ATK by 500. "Celtic Guardian" then destroys this card.
- Wall Shadow was a Fusion Monster created from "Shadow Ghoul" and "Labyrinth Wall" using "Polymerization". All of the above effects of Labyrinth Wall were still there, but it could also attack an opponents monster anywhere within the maze itself. If it was destroyed, Labyrinth Wall was Special Summoned back to the field.
