As the gang fights Alexander's servants, he watches from his giant stone monster, Reshef the Dark Being. As the rest of the gang defeat the servants' monsters, Alexander takes their power to summon Seven-Armed Fiend. Seven-Armed Fiend is then revealed to be the monster from Yugi's dreams.

- When Seven Armed Fiend is summoned, seven monsters were sacrificed to it. After it's destroyed later, only four monsters are returned; this suggests that is used the monsters' life energy for its powers.
