The vortex of Xyz opened, and the power of Chaos burst forth from within. An obsidian body descended slowly upside down from the rift. Its entire form was covered in matte metal armor, while exposed gear assemblies at its joints continuously seeped dark-red oil. Blood-colored patterns winding across its right leg armor writhed like living things, and a single steel wing burst open behind it. The tip of its three-meter wing blade split into five claw-like structures.
CNO.40. Gear Gigant Puppet of Gi-Gantic Devil's String, appear!
[CNO.40 Gear Gigant Puppet of Gi-Gantic Devil's String, ATK 3300]
Puppet of Gi-Gantic Devil's String was the Chaos Form evolved from Heaven's String, and its power had been upgraded as well. By removing one Xyz Material, the Chaos-formed Puppet of Gi-Gantic Devil's String could destroy all monsters on the opponent's Field with String Counters, then inflict damage equal to the combined ATK of those destroyed monsters.
Thus, the standard combo was to first Xyz Summon Heaven's String, place String Counters on the opponent's monsters, then rank it up into Puppet of Gi-Gantic Devil's String, destroy every monster that had just received a counter, and inflict damage.
But clearly, this effect overlapped with the earlier "Geargia Puppet Serial Killer," and it was not as powerful as Serial Killer. Puppet of Gi-Gantic Devil's String could only destroy monsters with String Counters on the Field, whereas Geargia Puppet Serial Killer could wipe the entire Field clean by removing just one material.
That was probably why IV had chosen to summon Serial Killer first, only revealing this Gear Gigant Puppet of Gi-Gantic Devil's String after being defeated. This Chaos monster was practically an inferior replacement for the Serial Killer from before, with its higher ATK being its sole advantage.
