This card has the same ATK, DEF and Level as "Steelswarm Hercules".
You have to pay Life Points to activate both monsters' effects.
According to the Overlay Guide 2, "Zielgigas" was brought back from the dead by the power of the "Gishki", who were controlled by the "lswarm", and gave the "lswarm" a fighting chance, but they were pushed back by "Gem-Knight Master Diamond", the ultimate "Gem-Knight" fusion.
This card's appearance also appears to be quite similar to Bhagwan Shiva; the Hindu deity representing destruction as it bears two sets of arms and Indian-esque armor.
This monster and "Gishki Psychelone" are, so far, the only "Gishki" Ritual Monsters that do not have the prefix "Evi-" in the name.
However, this is due to a misprinting, as both monsters have "Evi-" ("イビ-") in their Japanese names.
This card has the highest ATK and Level of all Aqua-Type monsters.
