- This monster appears in the artwork of "Barrage Blast" and "Upgrade".
- This monster is potentially based on the Schwerer Gustav, one of the biggest artillery pieces ever to have been fielded into battle.
- This monster could also be based on the Langer Gustav, an even bigger cannon that was never completed due to it being damaged from bombing raids mid-construction.
- This was the first Rank 10 monster to be released in OCG/TCG.
