Card Trivia:Ally of Justice Catastor
- This card appears in the artworks of "Descending Lost Star", "Mental Corruption" and "Mist Valley Thunder Lord".
- This was the first "Ally of Justice" monster to be released in the TCG.
- "Catastor" has a prototype version called "Ally of Justice Core Destroyer".
- "Ally Mind" is embedded in the head. Ironically, it can't be used to Synchro Summon this card unless its Level is decreased, since both cards are Level 5.
- However, according to the Duel Terminal storyline, Ally of Justice Catastor was created way before Ally Mind.
- It is identical to the "Quickdraw Synchron" and "Junk Warrior" situation.
- This card, along with "Brionac, Dragon of the Ice Barrier" and "Mist Wurm" were all short printed in Hidden Arsenal, so you would only find a maximum of 1 to 2 of each per-36-packs booster box, making them exceedingly rare.
- Alternatively, "Catastor" could be a play on the word "catastrophe" considering its powerful destruction effect.
- In the artwork for "Mist Valley Thunder Lord", it is carrying the head of "Catastor", implying that it defeated "Catastor". In the context of the actual card game, this would be impossible as "Mist Valley Thunder Lord" cannot beat "Catastor" due to the effect of "Catastor" that automatically destroys any non-DARK monster.
- This card has a "lswarm" counterpart, "Evilswarm Golem".
